Finding index position in for loop

Question

Is it possible to find the index of a list in a for loop without using a generator?

for character in string:
    if character == "a":
        print(get_index_somehow)

I am aware that you could use a generator in a for loop and get the index that way

for i in range(len(string)):
    character = string[i]
        if character == "a":
            print(i)

Just curious if it's possible
