Python: Get the current date time information

Python Datetime: Exercise-40 with Solution

Write a Python program to get the current date time information.

Sample Solution:-

Python Code:

import time
import datetime

print()
print("Time in seconds since the epoch: %s" %time.time())
print("Current date and time: " , datetime.datetime.now())
print("Alternate date and time: " ,datetime.datetime.now().strftime("%y-%m-%d-%H-%M"))
print("Current year: ", datetime.date.today().strftime("%Y"))
print("Month of year: ", datetime.date.today().strftime("%B"))
print("Week number of the year: ", datetime.date.today().strftime("%W"))
print("Weekday of the week: ", datetime.date.today().strftime("%w"))
print("Day of year: ", datetime.date.today().strftime("%j"))
print("Day of the month : ", datetime.date.today().strftime("%d"))
print("Day of week: ", datetime.date.today().strftime("%A"))
print()

Sample Output:

Time in seconds since the epoch: 1494232844.031525                                                            
Current date and time:  2017-05-08 14:10:44.031541                                                            
Alternate date and time:  17-05-08-14-10                                                                      
Current year:  2017                                                                                           
Month of year:  May                                                                                           
Week number of the year:  19                                                                                  
Weekday of the week:  1                                                                                       
Day of year:  128                                                                                             
Day of the month :  08

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")
