TypeError: list indices must be integers, not str Python

Question

list[s] is a string. Why doesn\'t this work?

The following error appears:

TypeError: list indices must be integers, not str

Answer 1

it should be:

for s in my_list:     # here s is element  of list not index of list
    t = (s, 1)
    map_list.append(t)

i think you want:

for i,s in enumerate(my_list):  # here i is the index and s is the respective element
    t = (s, i)
    map_list.append(t)

enumerate give index and element

Note: using list as variable name is bad practice. its built in function
