Python version 3.8 does not support a trailing 'L'

As an AI language model, I can not say for sure what you are trying to say. However, I can provide you with some information about the use of trailing 'L' in Python.

In Python 2.x, the trailing 'L' was used to indicate a long integer. For example, 10L would be a long integer. However, in Python 3.x, all integers are long integers by default, so the trailing 'L' is no longer needed.

If you are getting an error message about a trailing 'L' in Python 3.8, it is likely because you are using code that was written for Python 2.x and has not been updated for Python 3.x. In this case, you will need to remove the trailing 'L' from your code.

python def

In Python, `def` is a keyword used to define a function. The basic syntax of defining a function is:

def function_name(parameters):
    """docstring"""
    # code block
    return [expression]

Here, `function_name` is the name of the function, and `parameters` are the inputs that the function takes. The code block under the function definition is executed when the function is called, and the `return` statement specifies the value that the function returns (if any).

The `docstring` is a string literal that describes what the function does. It is optional, but it is good practice to include informative docstrings in your code to help others understand how to use your function.
