How do I create a incrementing filename in Python?

Question

Try setting a count variable, and then incrementing that variable nested inside the same loop you write your file in. Include the count loop inside the name of the file with an escape character, so every loop ticks +1 and so does the number in the file.

Some code from a project I just finished:

numberLoops = #some limit determined by the user
currentLoop = 1
while currentLoop < numberLoops:
    currentLoop = currentLoop + 1

    fileName = ("log%d_%d.txt" % (currentLoop, str(now())))

For reference:

from time import mktime, gmtime

def now(): 
   return mktime(gmtime()) 

which is probably irrelevant in your case but i was running multiple instances of this program and making tons of files. Hope this helps!
