While loop with enumeration in Python [duplicate]

I sometimes have this:

i = 0
while condition:
    ...
    i += 1

Here is an example situation: Create file but if name exists add number.

I don't know any option to do another way (except those discussed in Using enumerate function in while loops), but usually Python always has some syntactic sugar to avoid the manual "i = 0, ..., i += 1 pattern".

Is there an alternative in newest versions of Python? Something like (pseudo-code):

for i in enumerate(while(condition)):
    ...
