[英]why do i get the IndexError: list assignment index out of range
I am trying to get know the postion of a letter in a list and how many time it comes up.我想知道一封信在列表中的位置以及它出现了多少次。 when i get those positions i wanted to replace same postitions with in the list
right_user_input
.当我得到这些职位时,我想用列表
right_user_input
替换相同的职位。
but whenever i try to do that it returns this error IndexError: list assignment index out of range.
但是每当我尝试这样做时,它都会返回此错误
IndexError: list assignment index out of range.
can anyone tell why this is?谁能告诉这是为什么?
import random
import re
from words import words
# the word that the user needs to guess
the_guess_word = random.choice(words)
n = 0
# puts the random picked word in a list
l_guess = list(the_guess_word)
box = l_guess
# somethings are not yet finished
print("Welcome To The Guessing Game . \n You get 6 Guesses . The Words Are In Dutch But There Is 1 English Word . "
"\n If You Would Want To Try Again You Can Press (ctrl+Z)"
f"\n \n Your Word Has {len(the_guess_word)} letters ")
class hangman:
t = len(box)
right_user_input = []
# should create the amount of letters in the word
right_user_input.append(t * ".")
while True:
# the user guesses the letter
user_guess = input("guess the word : ")
# if user guesses it wrong 6 times he or she loses
if n >= 6 :
print("you lose!")
print(f'\n the word was {the_guess_word}')
break
# loops over until user gets it right or loses
if user_guess not in the_guess_word:
print("\n wrong guess try again ")
n += 1
# when user gets it right the list with the dots gets replaced by the guessed word of the user
if user_guess in the_guess_word :
print("you got it right")
# finds the position of the guessed word in the to be guessed the word
for m in re.finditer(user_guess, the_guess_word):
right_user_input[m.end()] = user_guess
print(right_user_input)
# this the error that i get
# i tried searching around but usually people have empty strings in my case that is not the issue .
# and the value in the right_user_input is len(the_guess_word) * "."

The problem is that you didn't setup right_user_input
correctly.问题是您没有正确设置
right_user_input
。 right_user_input.append(t * ".")
just makes the variable equal a single string of t dots ( ["....."]
) instead of t strings of 1 dot ( [".", ".", ".", ".", "."]
). right_user_input.append(t * ".")
只是使变量等于 t 个点的单个字符串 ( ["....."]
) 而不是 1 个点的 t 个字符串 ( [".", ".", ".", ".", "."]
)。
To fix this, declare the variable this way:要解决此问题,请以这种方式声明变量:
right_user_input = ["." for i in range(len(the_guess_word))]
right_user_input = ["." for i in range(len(the_guess_word))]
. right_user_input = ["." for i in range(len(the_guess_word))]
。
Also, replace right_user_input[m.end()] = user_guess
with此外,将
right_user_input[m.end()] = user_guess
为
right_user_input[m.end()-1] = user_guess
since arrays start at 0. right_user_input[m.end()-1] = user_guess
,因为 arrays 从 0 开始。
