我如何隨機選擇從輸入（蟒蛇）一詞

Question

我希望用戶輸入一個句子，然後隨機選擇該句子中的詞彙並打印。我不知道該怎麼做，有什麼幫助？ 目前爲止，我只能從句子中選擇一個字母。

Answer 1

你基本上需要做的是： 提示輸入，分割成單個的詞語，然後選擇一個隨機單詞與random library的幫助：

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
