import random
def ShowOne(words):
'''
words:参数是一个包含四个单词的列表
'''
i = random.randint(0,3)
print words[i]
# 防止一闪
raw_input()
# 假设从输入获取依次获取这4个单词
words = []
for i in range(0,4):
words.append(raw_input("Enter a word: "))
ShowOne(words)
直接用rand模块里的choice就行了
比如
from random import choice
lst = ['one', 'two', 'three', 'four']
choice(lst)
就行了
import random
words = ['one','two','three','four']
flag = random.randint(0,3)
print(words[flag])
