how do i make user only enter words in list code example

Example 1: get list as input

#to get integer list
integer_list = list(map(int, input().split()))
#to get char or str list, just replace int with str
str_list = list(map(str, input().split()))
#syntax of map(): map(dataType, iterable [, iterable2, iterable3,...iterableN])

    ele = [input(), int(input())]
