Question

我希望用户输入一个句子，然后在该句子中随机选择一个单词并打印出来。我不知道怎么做，有什么帮助吗？到目前为止，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，分成单个单词，然后在random library：

的帮助下选择一个随机单词

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

Answer 2

这可以满足您的要求，就像上面的答案一样，但是如果您愿意，可以使用此功能。

import random
sentence = input("Your sentence: ")
words = sentence.split()
words = random.shuffle(words)
yourword = words[0] # or, for more spoiled variation use: 
#yourword = words[random.randint(range(len(words)))]

Answer 3

#in this code we took the input as a list to make it easier taking each word of the sentence alone  
import sys , random 
sentence=sys.argv[1:]
r=random.choice(sentence)
print(r)
