Most efficient way to resolve the 'IndexError: list index out of range' error in Python?
问题
在运行Python脚本时，我遇到了一个'IndexError: list index out of range'错误。此错误发生在尝试访问列表中超出有效索引范围的索引时。
例如，考虑以下代码：
numbers = [1, 2, 3, 4, 5]
print(numbers[10])
在此代码中，列表numbers有5个元素，因此最高可用的索引为4。然而，代码尝试访问第10个索引，超出范围，导致'IndexError: list index out of range'错误。
要解决此错误并确保只访问列表范围内的索引，最有效的方法是什么？
英文:
When running a Python script, I am encountering an 'IndexError: list index out of range' error. This error occurs when trying to access an index in a list that is outside the range of valid indices.
For example, consider the following code:
numbers = [1, 2, 3, 4, 5]
print(numbers[10])
In this code, the list numbers has 5 elements, so the highest index available is 4. However, the code tries to access the 10th index, which is out of range, resulting in the IndexError: list index out of range error.
What is the most efficient way to resolve this error and ensure that I am only accessing indices within the range of the list?

以下是翻译的代码部分：
如果你指的是通过解决来限制索引，那么这是一个简单的方法：
numbers = [1, 2, 3, 4, 5]
print(numbers[min(10, len(numbers) - 1)])
希望这对你有帮助。
英文:
If by solving, you mean, capping index, then this is a simple way to do it :
numbers = [1, 2, 3, 4, 5]
print(numbers[min(10, len(numbers) - 1)])
