Question

Here is what I am trying to achieve: I want to replace

void some_function(int,  int *, float);

with

void some_function(int a, int *b, float c);

So far, I have tried to replace “,” with chr(97+i) as I loop through the string.

text = len("void some_function(int,  int *, float);")
i = 0
for j in range(0, length)
    if text[j] == ",":
       rep = " " + chr(97+i) + " .,"
       text = text.replace("," rep)
       i = i + 1
       j = 0 # resetting the index, but this time I want to find the next occurrence of "," which I am not sure

But this is not doing the job. Please let me know if there is a better way of doing this.

Answer 1

import re

i = 96
def replace(matches):
    global i
    i += 1
    return " " + chr(i) + matches.group(0)

re.sub(',|\)', replace, "void some_function(int,  int *, float);")
