Python: ValueError: min() arg is an empty sequence -


i trying find added file of specific type (.csv) in folder. getting error.

here code:

import glob newest = min(glob.iglob('results/*.csv'), key=os.path.getctime)

here error getting:

valueerror: min() arg empty sequence

what causing valueerror , how resolve it?

thanks in advance

you don't have .csv files in target location. try following should return none in such case.

my_glob = glob.glob('results/*.csv') newest = min(my_glob, key=os.path.getctime) if my_glob else none
