How to auto-increment in python

I am new to python. I want to print all available functions in os module as:

1 functionName 2 functionName 3 functionName 

and so on.

Currently I am trying to get this kind of output with following code:

import os cur = dir(os) for i in cur: count = 1 count += 1 print(count,i) 

But it prints as below:

2 functionName 2 functionName 2 functionName 

till end.

Please help me generate auto increment list of numbers, Thanks.

Its because you've re-defined the count variable or reset it to 1 for each loop again. I'm not into python but your code doesn't make sense since everytime the count variable is first set to 1 and then incremented. I'd simply suggest the following.

import os cur = dir(os) count = 1 for i in cur: count += 1 print(count,i) 
0

The pythonic way to do this is enumerate. If we pass the keyword argument start=1, the count will begin at 1 instead of the default 0.

import os cur = dir(os) for i, f in enumerate(cur, start=1): print("%d: %s" % (i, f)) 
1
