Question

I have a list of files in the same directory that are systematically named, eg. 'test01.ext','test02.ext','test03.ext'...'test99.ext'. I want to, in Python, pass a certain range of these files to a loop. However, I want to be able to determine which files I want to loop in a command line, eg. 'test45.ext' to 'test62.ext'. How would I do this?

Currently I’m using the following code:

for fname in sys.stdin :
   Some_loop(fname)

How would I choose (without manually entering all files from eg. 45 to 62) a range of files when prompted?
Thanks!

Answer 1

files = sys.stdin.splitlines()
for n in range(start,end):
  fname = 'test%02d.ext' % (n,)
  if fname in files:
    some_loop(fname)
