Their thinking ：
1. Get the input string , use input（）

2. use if The function judges that the length of the string is less than and not empty
3. use strip(’ ') Remove the spaces that may be entered on the left and right sides

5. Get the length of the last element of the list , Starting from the first character, the subscript is 0, In turn , Start with the last character , Subscript to be -1, Decrease in turn ,-2,-3....

words = input()
if len(words) <= 5000 and words is not None:
    words = words.strip(' ')
    word_list = words.split(' ')
    print(len(word_list[-1]))
