Python encoding/decoding of str, methods-CodePudding

Given a sentence string. Write the shortest word in a sentence. If there are several such words, then output the last one. A word is a set of characters that does not contain spaces, punctuation marks and is delimited by spaces, punctuation marks, or the beginning/end of a line.

Input: sentence = “I LOVE python version three and point 10”

Output: "I"

My attempt:

sentence = input("sentence: ")
words = sentence.split()
min_word = None
for word in words:
    if len(word) < len(words):
        min_word = word
print(min_word)

But output is : 10

Can you help me?

CodePudding user response：

this bug because of if len(word) < len(words):. It can be if len(word) < len(min_word): and to fix len(None) you can use this code:

sentence = input("sentence: ")
words = sentence.split()
min_word = words[0]
for word in words:
    if len(word) < len(min_word):
        min_word = word
print(min_word)
