    for file in iglob(inputpath):
        s1 = time.time()
        size = function(file) 
        s2 = time.time() - s1 
        with open(r'C:/Users/mach/Desktop/exetime.csv','a') as f:
            writer = csv.writer(f)
            writer.writerow({file,s2})

Answer 1

you can do as below. refer here

with open(r'C:/Users/mach/Desktop/exetime.csv','a',newline='') as f:
            writer = csv.writer(f)
            writer.writerow([file,s2])

newline='' is to avoid writing a unwanted newline (line ending is \r\n on Windows)
