In Python, there is often more than one way to solve a problem, and some solutions can be more “clever” or concise than others.
One of the advantages of Python is its simplicity and expressiveness, which allows you to write code that is easy to read and understand. However, this can sometimes lead to the temptation to write code that is clever but hard to understand, especially for people who are not familiar with the language.
It is generally a good idea to strike a balance between being clever and being readable. While it can be satisfying to come up with a clever solution to a problem, it is important to consider the maintainability and readability of your code, especially if you are working on a team or if your code will be used by others.
In general, it is always a good idea to strive for simplicity and clarity in your code, rather than trying to be overly clever.

from datetime import timedelta c, s = input().split() c = c.split(':') s = s.split(':') tc = timedelta(hours = int(c[0]), minutes = int(c[1])) ts = timedelta(hours = int(s[0]), minutes = int(s[1])) td = ts - tc # To not keep the seconds, which do not interest us print(':'.join(str(td).split(':')[:2])) |
This code calculates the difference between two times, represented as time deltas, and formats the result as a string in the format “HH:MM”.
The input is expected to be two strings in the format “HH:MM” separated by a space. The strings are split into two lists (c and s) using the split method. Each list is then converted to a time delta using the timedelta function and the int function to convert the hour and minute values to integers.
The difference between the two time deltas is calculated by subtracting tc from ts. The result is then formatted as a string by splitting the time delta into a list of strings using the split method, taking the first two elements of the list (which correspond to the hours and minutes), and joining them using the join method.
Finally, the formatted string is printed to the console.
The second, and by the way the only one to have shared his code, wrote it in JavaScript. I will rest it below.

inputs = readline().split(' ') var C = inputs[0].split(':') var S = inputs[1].split(':') t1=parseInt(C[0])*60+parseInt(C[1]) t2=parseInt(S[0])*60+parseInt(S[1]) t3=Math.abs(t1-t2) h=Math.floor(t3/60) m=t3%60 if(m.toString().length==1)m='0'+m print(h+':'+m) |
This code calculates the difference between two times, represented as strings in the format “HH:MM”, and formats the result as a string in the format “HH:MM”.
The input is expected to be two strings in the format “HH:MM” separated by a space. The strings are split into two lists (C and S) using the split method.
The time values are then converted to minutes by multiplying the number of hours by 60 and adding the number of minutes. The difference between the two times is calculated by subtracting t1 (the time represented by C) from t2 (the time represented by S).
The result is formatted as a string by dividing the difference in minutes by 60 to get the number of hours and taking the remainder to get the number of minutes. The hours and minutes are then concatenated into a string with a colon separator. If the number of minutes is a single digit, a leading zero is added to the string.
Finally, the formatted string is printed to the console.
Nothing special, but there is no picture, the standard Python library is really dense and practical, while JavaScript is really lacking. I love Python
