Python 为什么我会得到“一个”；列表索引超出范围“；错误？

这是我的节目：

   def FoundmovieNamesInQuery(userQueryPart,nameOfMovie):
        for userQueryPart in userQuery:
            for nameOfMovie in movieNames:
                if userQueryPart == nameOfMovie:
                    return True
        return False


    print("welcome")
    userQuery = input("use our quick search to find cinema times for films shwing today: ").lower().split()
    print(userQuery)

    with open("movies.txt")as file:
        lines = file.readline()
    slutionFound = False

    for line in lines:
        item = line.split(":")
        movieNames = item[0].split()
        movieTimes = item[1]
        if FoundmovieNamesInQuery():
            print(movieTimes)
            solutionFound = True
    if solutionFound == False:
        print("movie not found.\n please call us on 0800 020 030")

但当我运行它时，它会给出以下错误消息：

welcome
use our quick search to find cinema times for films shwing today: annabelle
['annabelle']
Traceback (most recent call last):
  File "C:\Users\FARUQE TALUKDAR\Downloads\online film.py", line 20, in <module>
    movieTimes = item[1]
IndexError: list index out of range

首先，您需要使用

readlines

而不是

readline

，它将读取整个txt

其次，需要将参数传递给函数

FoundmovieNamesInQuery（userQuery，movieNames）

---

是不是应该是lines=file.readlines（）？哇，这真的很管用。谢谢这样一个简单的错误让我第七天很头疼。一个初学者应该能够通过使用分治和

print（item）

调试来找出像这样的简单错误。下面是调试的基本指南。在这种情况下，我怀疑您有一行

不包含任何
：
字符。因此，您的
split
返回一个包含单个字符串的列表。
run along : this movie will be showing at 18.00
annabelle : this movie will be showing at 13.00
x-men : this movie will be showing at 7.00
