in Python, when you attempt to access an element using an index that lies outside the valid index range of the list, you're essentially telling the program to fetch something that isn't there, resulting in this common error.
The Python interpreter's response to such an error is to halt the execution of the program and display an error message likeIndexError: listindexoutofrange, directly pointing out the misuse of indices. This mechanism prevents programs from proceeding with invalid data access, which could lead to...
