'NoneType' object has no attribute 'spilt'

This error occurs when you try to call the 'split' method on a variable that is of type 'NoneType'. This means that the variable is not referencing any object in memory and does not have any attributes or methods associated with it.

To fix this error, you need to ensure that the variable is properly initialized and referencing a valid object before calling any methods on it. You can also add a check to ensure that the variable is not None before calling any methods on it.

For example, instead of writing:

my_string = None
words = my_string.split()

You can write:

my_string = "Hello world"
if my_string is not None:
    words = my_string.split()
else:
    print("my_string is None")
