我如何随机选择从输入（蟒蛇）一词

Question

我希望用户输入一个句子，然后随机选择该句子中的词汇并打印。我不知道该怎么做，有什么帮助？ 目前为止，我只能从句子中选择一个字母。

Answer 1

你基本上需要做的是： 提示输入，分割成单个的词语，然后选择一个随机单词与random library的帮助：

import random 

inp = input("Input: ") # prompt for input 
# With an example: 
# Input: This is a sentence 
# produces the string inp="This is a sentence" 
list_input = inp.split() # split up the sentence into a list of words 
# In our example: 
# list_input = ["This","is","a","sentence"] 

print(random.choice(list_input)) # choose a random item from the list of words 
# In our example the print statement would choose randomly one of the four words
