Python: Convert two date difference in days, hours, minutes, seconds
Python Datetime: Exercise-37 with Solution
Write a Python program to convert two date difference in days, hours, minutes, seconds.
Sample Solution:
Python Code:
from datetime import datetime, time
def date_diff_in_seconds(dt2, dt1):
timedelta = dt2 - dt1
return timedelta.days * 24 * 3600 + timedelta.seconds
def dhms_from_seconds(seconds):
minutes, seconds = divmod(seconds, 60)
hours, minutes = divmod(minutes, 60)
days, hours = divmod(hours, 24)
return (days, hours, minutes, seconds)
#Specified date
date1 = datetime.strptime('2015-01-01 01:00:00', '%Y-%m-%d %H:%M:%S')
#Current date
date2 = datetime.now()
print("\n%d days, %d hours, %d minutes, %d seconds" % dhms_from_seconds(date_diff_in_seconds(date2, date1)))
print()
Sample Output:
858 days, 12 hours, 34 minutes, 21 seconds

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")
