As Python uses zero-based indexing, when you try to access an element at an index less than 0 or greater than or equal to the list’s length, Python tells you via this error that the specified index is out of the permissible bounds of the list's length. Here are some common scenarios...
Now we know that the first element in my_list is ‘a’, we can use this information to return the index number at this position as well.In our simplified example, we know that this index number is 0. However, sometimes we might not know the index number that corresponds to a certain...
