Create multiple directories

[Paul Lemelle]

I am somewhat new to Python and I am trying to create a program that
automatically creates directories from a range of numbers. I
researched the os.mkdir & os.makedirs methods, but they do not seem to
(I don't know) how to include an argumnet to step through my list.

I woudl like to do the follwoing:
1) Ask the user how many folders to create
2) take raw_input and then translate it into a while loop that steps
through the os.mkdir process.

Any would help would be appreicated.

Maybe something like this?

import os

def mkdirs(n):
for i in range(n):
os.mkdir("%d" % i)

if __name__ == '__main__':
mkdirs(int(raw_input("How many folders should I create? ")))

Maybe something like this?

import os

def mkdirs(n):
     for i in range(n):
         os.mkdir("%d" % i)

if __name__ == '__main__':
     mkdirs(int(raw_input("How many folders should I create? ")))

Maybe something like this:

import os

num_str = raw_input("Enter number of dirs to create: ")
num = int(num_str)

for i in range(num):
dir_name = "new_dir%s" % i #same result as "new_dir" + str(i)
os.mkdir(dir_name) #creates dirs in current directory

for i in range(num):
dir_name = "new_dir%s" % i #same result as "new_dir" + str(i)
os.mkdir(dir_name) #creates dirs in current directory

I find it's useful to keep all the filenames the same length and
put leading zeros in the directory numbers, so that sorting their
names lexicographically puts them in numerical order. Untested:

fmt = "new_dir%0%d" % len(str(num))
for i in xrange(num):
os.mkdir(fmt % i)

Or if num is unknown but you have some upper bound like 1000,
you could just use %05d or something like that.

 

[Paul Rubin]

fmt = "new_dir%0%d" % len(str(num))

Typo, that was supposed to say "new_dir%%0%d" ...

7stud & Jeff,

Thanks for yoru input - there's still a few things for me to learn.
