Python 3.5 "for loop" "enumerate()" Select 列表中的单词

Question

嗨，我是新来的，我刚开始学习python

wordList中的单个单词将被称为“单词”作为变量。

顺便说一句，我会为 python 英语语法生成程序设置这个。

我还想尝试输入一个循环，为 wordList 中的每个单词重复一次。尝试使用带有“enumerate()”函数的 for 循环，但我总是卡住。任何帮助都会很棒。

# Import the random module to allow us to select the word list and questions at random.
import random
candidateWords = ['HELLO', 'GOODBYE', 'NAME', 'DAY', 'NIGHT', 'HOUR', 'POTATO', 'BIG', 'SMALL', 'GOOD', 'BAD', 'YES', 'NO', 'HOUSE', 'QUESTION', 'BALLOON', 'CAT', 'DUCK', 'PIGEON', 'POSTER', 'TELEVISION', 'SPY', 'RHYTHM', 'SUBSTANTIAL', 'SNOW', 'MAGNET', 'TOWEL', 'WALKING', 'SPEAKER', 'UNCHARACTERISTICALLY']
# places words down in a list
s = random.sample (candidateWords, 5)
for index,w in enumerate(s):
print(index,w)

Answer 1

如果您的问题是如何使用枚举，这里有一个适用于您的代码示例的应用程序：

import random
candidateWords = ['HELLO', 'GOODBYE', 'NAME', 'DAY', 'NIGHT', 'HOUR', 'POTATO', 'BIG', 'SMALL', 'GOOD', 'BAD', 'YES', 'NO', 'HOUSE', 'QUESTION', 'BALLOON', 'CAT', 'DUCK', 'PIGEON', 'POSTER', 'TELEVISION', 'SPY', 'RHYTHM', 'SUBSTANTIAL', 'SNOW', 'MAGNET', 'TOWEL', 'WALKING', 'SPEAKER', 'UNCHARACTERISTICALLY']

s = random.sample (candidateWords, 5)

# loop through the list using enumerate

for index,w in enumerate(s):
    print("word {} out of {} is {}, nb vowels is {}".format(index+1,len(s),w,countVowels(w)))

产出

word 1 out of 5 is NIGHT, nb vowels is 1
word 2 out of 5 is BALLOON, nb vowels is 3
word 3 out of 5 is SUBSTANTIAL, nb vowels is 4
word 4 out of 5 is BIG, nb vowels is 1
word 5 out of 5 is PIGEON, nb vowels is 3

请注意，如果不需要索引，则不必使用枚举：

for w in s:
    print(w,countVowels(w))

对于你的计数元音（因为每个人似乎都认为这是某个时候的问题），你可以这样做，Y 是否是元音取决于你，因为它不清楚（Oxford )

def countVowels(word):
    return sum(word.count(x) for x in "AEIOUY")

生成器 comp 将为单词中的每个元音应用计数字符，然后应用标准求和函数。
