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.

Syntax

 
# 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 = datetime.now()
# Display date, time without Formatting
  print(dt)

Output:

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

Filter datetime output as per our requirement.

• Filter date

Syntax

 #  dt = datetime.now()
 #  show_date = dt.date()

 # print (show_date)
 

Output:

 
  datetime.date(2021, 6, 7)

Filter only Day

 #  dt = datetime.now()
 #  show_day = dt.day

 # print (show_day)
 

Output:

 
  7

• Filter Month

Syntax

 #  dt = datetime.now()
 #  show_month = dt.month

 # print (show_month)
 

Output:

 
  6

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

Syntax

 
 #  dt = datetime.now()
 #  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)
 

Output:

 
 060721
 06072021
 20210607
 Mon 06 21
 Monday-06-2021
 02 AM 32

 myprefix-060721-mysuffix
