Question

I want to write my output code in csv file in this way, first column in csv contain file name and second column contain the value of exetime (s2), how can do that?

 inputpath = 'C:/Users/mach/Desktop/hh/c*.csv'
    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)
