Instead of writing your code in a single long file you can (and should) call separate functions to handle discrete tasks. In addition to all the modules supplied by third parties, this tutorial shows you how to create your own libraries of useful functions.
See our full range of Python training resources, or test your knowledge of Python with one of our Python skills assessment tests.

Hi,
What is the difference between the function syntax used in the video:
def FunctionName(Parameter: DataType) -> ReturnDataType:
return [expression]
and the "usual" syntax:
def FunctionName(Parameter):
return [expression]
Is it just a more detailed coding syntax for clarity purpuses or there are other reasons/benefits that make it preferable for someone to use it?
Thanks

The main difference is that when you type in Parameter., VS Code will know that the parameter should hold a string/int/float/whatever, and come up with the appropriate methods specific to this data type. But this is a pretty big advantage.
