Question

I’m trying to find how to create sequential directories with specific padding. For a given number it should create directories:

def createDirectories(number=10, name='seq'):
    for i in range(1, number+1):
        os.mkdir(name+i)

But it should produce directories in following naming convention

seq0010
seq0020
seq0030
...
seq0100

How to format numbers in that way?

Answer 1

You can use this expression to obtain the directory name seq0010 from the input 1:

dirName = 'seq%03d0' % 1

Replace 1 with i and you’re set.
