How to get last Friday?

Question

The code below should return last Friday, 16:00:00. But it returns Friday of previous week. How to fix that?

now = datetime.datetime.now()
test = (now - date         


        

Answer 1

Could be lame but to me simplest. Get the last day of the current month and start checking in a loop (which wouldn't cost anything since max loops before finding last friday is 7) for friday. if last day is not friday decrement and the check the day before.

import calendar
from datetime import datetime, date

def main():
    year = datetime.today().year    
    month = datetime.today().month  
    x = calendar.monthrange(year,month)
    lastday = x[1]
    while True:
        z = calendar.weekday(year, month, lastday)
        if z != 4:
            lastday -= 1
        else:
            print(date(year,month,lastday))
            break

if __name__ == "__main__":
    main()
