Time Delta

Problem link : https://www.hackerrank.com/challenges/python-time-delta/problem

Difficulty : Medium

Tip

• First of all, we should convert timestamp string to datetime
• We should write a format string, to describe the meaning of timestamp string 
• For example, 'Sun' means the Sunday, to convert 'Sun' to Sunday(as a part of datetime), format string should be '%a'
• datetime is good class to convert whole timestamp :)
• total_seconds() is one of method, to print datetime as seconds
• Don't forget that we should print absolute value, so there is no minus value

Solution

#!/bin/python3 import math import os import random import re import sys from datetime import datetime as dt # Complete the time_delta function below. def time_delta(t1, t2): fmt = '%a %d %b %Y %H:%M:%S %z' return (dt.strptime(t1, fmt) - dt.strptime(t2, fmt)).total_seconds() if __name__ == '__main__': fptr = open(os.environ['OUTPUT_PATH'], 'w') t = int(input()) for t_itr in range(t): t1 = input() t2 = input() delta = time_delta(t1, t2) fptr.write(str(abs(int(delta))) + '\n') fptr.close()
