Python Script to create new JIRA tickets using JIRA API


Python Script with below JIRA operations

  • Fetch JIRA ticket details using JIRA API.
  • Create JIRA ticket using JIRA API

Information to collect before using script.
  • Get your organization JIRA URL handy with you.
    • Can be retrieved from any JIRA ticket URL, respective URL has FQDN that's the JIRA URL dedicated for your organization.
  • Know your JIRA project/space name.
    • Login to any of your JIRA tickets.
    • From top navigation panel, select projects and check the name associated with the project, project name will be single word without any space.
  • Know JIRA field/mandatory fields within your ticket, before you create a ticket via API.
    • Will know how to fetch details about it from our python script, get_jita_details method can be used to get details for field

Script has one class and two methods, will know how and when to use one by one.
  • JiraHandler ( Class )
  • get_jira_details ( Method ) - Can be used to fetch JIRA ticket details.
  • create_jira_cr_ticket( Method ) - Can be used to create new JIRA ticket. 
Note : 
  • For simplicity, i have used basic authentication method to authenticate to JIRA servers, although for some sort of security instead of using plain text password, have encoded it using base64 authentication.
  • You need to ready with the Payload data json file, before you go ahead and create a new JIRA ticket, this file can be of any name but please content is in JSON format.


import requests
import json
import base64
from requests.auth import HTTPBasicAuth

# Inorder to encrypt/decrypt your credentials using base64 module as below.
# To encode --> base64.b64encode(bytes("random", "utf-8"))
# To decode --> base64.b64decode("cmFuZG9t").decode("utf-8")

class JiraHandler:
    def __init__(self, username):
        print('Loading Instnace variables...')
        self.username = username
        self.securestring = base64.b64decode("replaceItwithYourCredential").decode("utf-8")
        self.url = ""

    def get_jira_details(self,jira_ticket):

        try :
            auth = HTTPBasicAuth(self.username, self.securestring)
            get_details_url = self.url + jira_ticket

            headers = {
               "Accept": "application/json"
            print("retrieveing", jira_ticket, "details...")
            response = requests.request(
            print(json.dumps(json.loads(response.text), sort_keys=True, indent=4, separators=(",", ": ")))
        except Exception as e:
            return e

    def create_jira_cr_ticket(self, filename):
        get_details_url = self.url

        auth = HTTPBasicAuth(self.username, self.securestring)

        headers = {
           "Accept": "application/json",
           "Content-Type": "application/json"
            with open(filename, "r") as re_read_file:
                payload =
                print("Creating new JIRA...")
                response = requests.request(
                print(json.dumps(json.loads(response.text), sort_keys=True, indent=4, separators=(",", ": ")))
        except Exception as filenotfound:
            print("Can't load file..", filenotfound)


How to use it, 
  • Load Instance variable by calling class and provide your JIRA username as an input.
# Initiate Class and load instance variable.
d = JiraHandler("your_JIRA_Username")
  • Call method get_jira_details and add JIRA ticket as method input, for example if we want to get details about a specific JIRA ticket CKPROJ-6162, we must call the method as described below.
# Call below method to get JIRA ticket details.
  • Before calling method create_jira_cr_ticket, dump json content within a json file, for instance i have created a file named payload_data.json and it looks somehow like below.
    • Thinking how to find it, use method get_jira_details, it will give you an idea for the field used within your project's jira ticket.
        "fields": {
              "key": "CKPROJ"
           "summary": "My Dummy Ticket created by REST API",
           "description": "Dummy CR for REST API Test",
           "confluence": "Dummy Confluence Page Link",
           "verification_steps": "Verification Plan",
           "issuetype": {
              "name": "Change Request"
Once you are ready with the payload data, save it within a JSON file and call method providing payload_data.json file as an input to it, as an output script will return the JIRA ticket details.
# Call below method to create new JIRA ticket

Hope this script can have help in any sort, for any help comment please.

Python Encode and Decode string using BASE64 module


base64 is a python library that can be used to encrypt and decrypt strings and characters, that can have a multiple use case.

One common use case is instead of directly pasting a plain text credential parameters into a file or as a parameter and that can be later decrypted using the decode statements within the program.

Within this blog post, we will cover.
  • How can we encrypt strings using base64
  • How can be decrypt the above base64 encrypted string using bas64 decoder.

Please note the two important points before we use this module.

  • base64 encode and decode functions both require a bytes-like object. In order to get our string into bytes, we must encode it first using Python's built in encode function. Most commonly, the UTF-8 encoding is used.
  • Encryption of same string using Linux command line interface and python shell differs, please use the same environment for both the encryption and decryption.

Here in this example, we will encrypt our string "cyberkeeda@123" and later we will decrypt it.


# Encryption Block 

import base64
base64.b64encode(bytes("cyberkeeda@123", "utf-8"))
Output for the above.


Below code can be use to decrypt the above, please use only the string content enclosed within string to decrypt, so for the above example output consider string leaving the b ( byte ) identifier.
# Decryption Block 

import base64

Output for the above.

Hope this small piece of snippet will help you in some context.

How to get yesterday's date using Python timedelta


How to use datetime module to get yesterday's date.

All of us use Python's date time library for multiple date/time task, there is an additional function named as timedelta that can be used to get previous date as per requested varaible.

Let's go through it :)

Script to extract yesterday date

# Python script to get yesterday date.
from datetime import date, timedelta # Block to get present day data today = print("Today's date : ", today.strftime('%Y-%m-%d')) # Block to get yesterday data yesterday = today - timedelta(days = 1) print("Yesterday's date : ", yesterday.strftime('%Y-%m-%d'))


Today's date : 2021-06-29
  Yesterday's date : 2021-06-28

Same way, we can change the timedelta to n number of day ( day = n )
Below, we will extract the 4 days old date

Script to extract yesterday date

# Python script to get yesterday date.
from datetime import date, timedelta # Block to get present day data today = print("Today's date : ", today.strftime('%Y-%m-%d')) # Block to get yesterday data yesterday = today - timedelta(days = 4) print("Yesterday's date : ", yesterday.strftime('%Y-%m-%d'))


Today's date : 2021-06-29
  Yesterday's date : 2021-06-25

How to use, Python's DateTime Module


Python's Date Time Module:
    Python's datetime module ships with default python package which you can't skip for sure sooner or later you will come to know about it.
This module will help you to verify multiple checks and algorithms based upon date time filter.

I will keep on updating the post as per my learnings and used in practical scenarios.
Let's go through it :)

Basic Usage of date time
  • Import module and display current date.

# Import datetime function from datetime library
from datetime import datetime
datetime.datetime(2021, 6, 7, 2, 43, 32, 276412)

# Create object and store value##
  dt =
# Display date, time without Formatting


datetime.datetime(2021, 6, 7, 2, 43, 32, 276412)

Filter datetime output as per our requirement.
  • Filter date

# dt =
# show_date =

# print (show_date)

Output:, 6, 7)

Filter only Day

# dt =
# show_day =

# print (show_day)



  • Filter Month

# dt =
# show_month = dt.month

# print (show_month)



Use datetime strftime to format date/time as per our need

    Below are some identifier to use while formatting.
    • %a  : Day of week (Short )
      • Mon, Tue, Wed, ... Sat, Sun
    • %A : Day of week (Full )
      • Monday, Tuesday, Wednesday .. Saturday, Sunday
    • %m : Month  ( Two digit number )
      • 01,02,03,04 .... 10,11,12
    • %y : Year ( Short, Two digit number )
      • 19,20,21
    • %Y : Year ( Full)
      • 2019,2020,2021
    • %d : Date ( Two digit number )
      • 01,02,03,04, 22,23,30,31

    Use Strftime as per our need.
    • With or Without Variables

    # dt =
    # show_val1 = dt.strftime('%m%d%y')
    # show_val2 = dt.strftime('%m%d%Y')
    # show_val3 = dt.strftime('%Y%m%d')
    # show_val4 = dt.strftime('%a %m %y')
    # show_val5 = dt.strftime('%A-%m-%Y')
    # show_val6 = dt.strftime('%I %p %S')
    # show_val7 = dt.strftime('%-j')
    # show_val8 = dt.strftime('myprefix-%m%d%y-mysuffix')

    # print (show_val1)
    # print (show_val2)
    # print (show_val3)
    # print (show_val4)
    # print (show_val5)
    # print (show_val6)
    # print (show_val7)

    Python - Send HTML Table as email body.


    A python base package to send emails.

    Within this post, we will cover.

    • How to use prettytable library to create tabular data in console.
    • How to convert prettytable tabular data output in HTML format
    • How we can send HTML email using Python.
    • How can we integrate mime with email.
    • Code snippet to send HTML email along with Texr
    • How to send email as MultiPart message content ( Text + HTML) 

    We will start with the use case:

    • I have a html table and and a Link that must be within the same email body and not as an attachment.
    • So for now, i am using PreetyTable to provide output of my table in HTML format.


    Intended Table.


    How to create Tabular data in CLI using prettytable.
    from prettytable import PrettyTable
    tabular_fields = ["Firstname", "Lastname", "Age"]
    tabular_table = PrettyTable()
    tabular_table.field_names = tabular_fields 
    tabular_table.add_row(["Jill","Smith", 50])
    tabular_table.add_row(["Eve","Jackson", 94])
    tabular_table.add_row(["John", "Doe", 80])
    >>> print(tabular_table)
    | Firstname | Lastname | Age |
    |    Jill   |  Smith   |  50 |
    |    Eve    | Jackson  |  94 |
    |    John   |   Doe    |  80 |

    To print the data as an HTML output use the below code snippet
    from prettytable import PrettyTable
    tabular_fields = ["Firstname", "Lastname", "Age"]
    tabular_table = PrettyTable()
    tabular_table.field_names = tabular_fields 
    tabular_table.add_row(["Jill","Smith", 50])
    tabular_table.add_row(["Eve","Jackson", 94])
    tabular_table.add_row(["John", "Doe", 80])
    >>> print(tabular_table.get_html_string())

    Now as we already know how to create html output for a specific table using prettytable, we will use the same html output within our email body.

    • Here is the code.

    import smtplib
    from email.mime.multipart import MIMEMultipart
    from email.mime.text import MIMEText
    def trigger_email():
        my_message = tabular_table.get_html_string()
        text = "Hi!\nHow are you?\nHere is the link you wanted:\n"
        html = """\
                table, th, td {
                    border: 1px solid black;
                    border-collapse: collapse;
                th, td {
                    padding: 5px;
                    text-align: left;    
        <p>Customer Inventory!<br>
           Here are the details?<br>
           Link to register. <a href="">link</a> you wanted.<br>
        """ % (my_message)
        part1 = MIMEText(text, 'plain')
        part2 = MIMEText(html, 'html')
        sendFrom = 'Purchase Update <>'
        sendTo = ''
        # Create the root message and fill in the from, to, and subject headers
        msg = MIMEMultipart('alternative')
        msg['Subject'] = 'Purchase details Status'
        msg['From'] = strFrom
        msg['To'] = strTo
        smtp = smtplib.SMTP('')
        smtp.sendmail(strFrom, strTo, msg.as_string())
    So modify the above with your requirement.

    Python : Selenium and Chromedriver to take webpage screenshot and send it via email.

    Browser Automation using Python

    Within this post, we will cover.

    • Use of selenium and chromedriver to take screenshot of most recent webpage status.
    • Will leverage the basic preinstalled libraries to send email.
    • Will know, how we can send an image as a part of email body not as an attachment.
    • Will use the headless mode option of chromdriver, that's is the entire operation will run in background no GUI chrome events will be observed.

    We will start with the use case:

    • if you have a requirement to check the current status of a webpage multiple times within a day/hour.
    • If you have multiple of webpages to look into periodically without opening any of it, check status of directly from your inbox only.
    We will use a python script here and perform the below operations sequentially.
    1. Take screenshot of webpage using Python selenium library and google chrome webdriver and save it in our folder by name screenshot.png
    2. Use Python base library email and use it's multipart function to draft image as an email body.
    3. Use Python base library to send email using SMTP server.
    • Download mandatory requirements.
      • Install selenium library from PIP
    C:\Users\cyberkeeda> pip install selenium
    First confirm which chrome browser you have on your system, for this open Chrome Browser --> Click on 3 dots at the top right corner of chrome --> Help
    --> About Chrome Chrome --> You will get google chrome version.
    • Create an new directory and place your above chrome webdriver into it.
    • Note your organizations SMTP server URL/IP.
    • Create a new Python file and paste the below script lines within it.
    • Paste and save your python script and replace the below lines with yours.
      • driverPath  : Replace it with the path you have kept your downloaded chromedriver 
      • chrome_options.add_argument('window-size=1920,1080')  : Replace it with resolution what you want for the screenshot.
        • 720p = 1280 x 720 - is usually known as HD or "HD Ready" resolution
        • 1080p = 1920 x 1080 - is usually known as FHD or "Full HD" resolution
        • 1440p = 2560 x 1440 - is commonly known as QHD or Quad HD resolution
      • driver.get(''): Replace it your URL.
      • sendFrom : Replace it your sender's email address.
      • sentTo: Replace it your recipient email address. ( You can use same email for sendFrom and sendTo)
      • smtp = smtplib.SMTP('') : Replace it your own smtp server or IP.
