Days Between Dates[Pro]

Difficulty: Medium


Problem Statement:

You need to calculate exactly how many days have passed between the two dates.

Task: 

Calculate how many days have passed between two input dates, and output the result. 

Input Format: 

Two strings represent the dates, the first date should be the older date. 
Date format: Month DD, YYYY

Output Format: 

A number representing the number of days between the two dates.

Sample Input: 

August 15, 1979
June 15, 2018

Sample Output: 

14184

Explanation:

14184 days have passed between the two input days.

Solution:

from datetime import date
x=input().split(',')
y=input().split(',')
x1=x[0].split()
y1=y[0].split()
print(x1)
print(y1)
l=['January','February','March','April','May','June','July','August','September','October','November','December']
d1=date(int(x[1]),int(l.index(x1[0])),int(x1[1]))
d2=date(int(y[1]),int(l.index(y1[0])),int(y1[1]))
print((d2-d1).days)

Explanation:

The main objective of this problem is to find the no of days between the given dates. In python, we have date() method to pass date as an argument. By subtracting the present date with the previous date we will get the output in date format. So, to convert into days use .days. The syntax of date method is date(year, month, date).

2. Mostly you will understand the problem while reading input, output, and Output explanation.

3. Now, Divide your Logic into 3 steps:


    step1: Input & output
                
                check whether you have written the correct syntax for input. To check you have to print the input.


   step2: Build your own logic with proper indentation.


    step3: Print the expected output.

Thank you!
