Calculate percentage between startTime, currentTime and endTime

I want to make a progress bar. To achieve this first i need percentage.

For example i watch the movie. i know when movie starts (startTime) and when ends (endTime).

startTime = "09:40" currentTime = "11:52" endTime = "13:05"

So i need to calculate current percentage of playing.

Any help is appreciated, thanks!

from datetime import datetime

timefmt = "%H:%M"
startTime = datetime.strptime("09:40", timefmt)
currentTime = datetime.strptime("11:52", timefmt)
endTime = datetime.strptime("13:05", timefmt)

ratio = (currentTime - startTime) / (endTime - startTime)
print(f"{ratio:5.2%}")

you can parse your strings into a datetime object; those can be subtracted (which will return a timedelta object).

then just use sting formatting in order to print the ratio in percent.

It can be done using the datetime module as already mentioned in an answer, but this is a more brute-force or general approach and would work even if the time is in HH:MM:SS format

startTime = "09:40" 
currentTime = "11:52" 
endTime = "13:05"

def changeToMin(time):
    arr = list(map(int, time.split(':')))
    seconds = 0
    for n,i in enumerate(arr):
        seconds  = i*60**(len(arr)-n-1)
    return seconds
    
def precentage(start, end, current):
    return (current-start)*100/(end-start)
    
print(precentage(changeToMin(startTime), changeToMin(endTime), changeToMin(currentTime)))
