Question

I am working with files and after processing them, I need to save them with numerical names in an ascending order such as 1.txt, 2.txt and so on.
Manually I would do as below:

Variable_1 = "C:\\1.txt"
Variable_2 = "C:\\2.txt"

Answer 1

for i in range(10):
    filename = "C:\\%d.txt" % i
    with open(filename, 'a') as f:
        ....

it’s as simple as this, but you could also use generators to create filenames (it’s up to you)
