我不知道为什么会出现此错误或索引超出范围。我在 jupyter 笔记本中使用 Python 3.0

Question

import random
from IPython.display import clear_output

dictionary = open("words_50000.txt","r")
dict_5000 = dictionary.readlines()
guess = random.choice(dict_5000).lower().strip('\n')
no_of_letters = len(guess)
game_str = ['-']*no_of_letters
only_length=[]

def word_guesser():
    only_length_words()
    print(dict_5000)


def only_length_words():
    for i in range(len(dict_5000)):
        if len(dict_5000[i].strip('\n'))!=no_of_letters:
            dict_5000.pop(i)    

word_guesser()

IndexError: list index out of range

Answer 1

问题是您使用的是 pop()，它破坏了列表，但您也在遍历列表。因此，假设您弹出的列表中有一个元素。现在，残缺列表的长度比原始列表短，但 for 循环仍将尝试迭代直到列表的原始长度，这导致 IndexError.

I don't know why I'm getting this error or index out of range. I'm using Python 3.0 in jupyter notebook
