python program to replace a character in string

so here is my relativly simple code:

def testaufruf(pfade):


   part = [i for i,x in enumerate(s) if x=="$"]




My problem is I want to pass something like[Test$path1]

now I take this Test$path1 make it an list and want to replace every $ with an \

These lines work:


part = [i for i,x in enumerate(s) if x=="$"]


They return me the place where the $ is located but the second part to replace the $ does not work. I did search a lot but couldnt find a solution to this problem.

Thanks for help in advance.

part = pfade.replace('$', '\\')

part = [i for i,x in enumerate(s) if x=="$"]

to solve this:

parts = [i for i,x in enumerate(s) if x=="$"]
for part in parts:
    s[part] = '\\'
