Why am I getting an 'IndexError: list index out of range' in Python?

IndexError: List Index Out of Range

When attempting to access a list item via indexing, the "IndexError: list index out of range" exception arises. This error indicates that the specified index exceeds the number of items in the list.

In your case, you're trying to print line 53 of an output. However, this error message suggests that the line does not exist in the list.

Index Start

Remember that in Python, indexing starts from 0. So, if you have a list with 53 items, the last item's index is 52, not 53.

Example

my_list = list(range(53))
print(my_list[52])  # Last item

In this example, my_list[52] will return the last item in the list, which is 52.

Additional Information

The IndexError is raised when the specified index is:

• Less than 0 (negative index)
• Equal to the length of the list
• Greater than the length of the list

Understanding the index start and the conditions for raising an IndexError is crucial to avoid out-of-range issues when working with lists.
