Finding the index of a list in a loop

I have a simple question. If I have a for loop in python as follows:

for name in nameList:

How do I know what the index is for the element name? I know I can some something like:

i = 0
for name in nameList:
    i= i + 1
    if name == "something":
        nameList[i] = "something else"

I just feel there should be a more readable way of doing this...

Solution

  • Use the built in function enumerate.

    for index, name in enumerate(nameList):
    ...
