Question

I am stuck on making list using python.

I want to make m x n files such as file00.txt, file01.txt, …, and file99.txt, but when I tried to make it, it shows some errors. Please let me help out.

filename = []

for i in range(0, sm):
    filename.append('') 
    for j in range(0, sn):
        filename[i].append('')

Thanks.

You could try something like this:

filenames = []

for i in range(0, sm):
    row = [] 
    for j in range(0, sn):
        row.append('') # I assume you want to do something more here
    filenames.append(row)
