Python: Get the dates 30 days before and after from the current date

Python Datetime: Exercise-28 with Solution

Write a Python program to get the dates 30 days before and after from the current date.

Sample Solution:-

Python Code:

from datetime import date, timedelta

current_date = date.today().isoformat()   
days_before = (date.today()-timedelta(days=30)).isoformat()
days_after = (date.today()+timedelta(days=30)).isoformat()  

print("\nCurrent Date: ",current_date)
print("30 days before current date: ",days_before)
print("30 days after current date : ",days_after)

Sample Output: 

Current Date:  2017-05-06                                                                                     
30 days before current date:  2017-04-06                                                                      
30 days after current date :  2017-06-05

Python: Tips of the Day

Find current directory and file's directory:

To get the full path to the directory a Python file is contained in, write this in that file:

import os 
dir_path = os.path.dirname(os.path.realpath(__file__))

(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)

To get the current working directory use

import os
cwd = os.getcwd()

Documentation references for the modules, constants and functions used above:

  • The os and os.path modules.
  • The __file__ constant
  • os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
  • os.path.dirname(path) (returns "the directory name of pathname path")
  • os.getcwd() (returns "a string representing the current working directory")
  • os.chdir(path) ("change the current working directory to path")
