列表不显示 - 仅显示空括号

Question

我试图创建识别任务。我有一个.txt文件，里面有600个单词。从这个列表中，我试图创建子列表（例如List1，List2。）由于某种原因，我无法从子列表中获取单词列表。它只返回[]。请帮忙！！

wordNum = 0

# Create list
wordList = []
with open('mfwords.txt','r') as f:

    for line in f:

        wordNum = wordNum+1

    for word in line.split():

        wordList.append(word)

 # Shuffle list
import random

random.shuffle(wordList)

# Number of words in list
listLen = 50

# List 1 is first 50 words of wordList
list1 = wordList[0:50]

# List 2 is first 100 words of wordList
list2 = wordList[0:100]

Answer 1

您的with open区块对我来说并不合适。第二个for需要在第一个{，1}内，否则它只会在line指向文件的最后一行时执行。尝试：

with open('mfwords.txt','r') as f:
    for line in f:
        for word in line.split():
            wordList.append(word)
