An Example Function

Before you can understand decorators, you must first understand how functions work. This lesson covers

  • What functions are
  • What goes into functions
  • How functions can be used as arguments for other functions

You created “def my_function():” but then you called my_func(), but you should have called my_function(), since my_func() will call another function “def my_funct():” which wasn’t defined yet. This might be confusing to a beginner. I hope this is clear to everyone. Great course so far!

Arguments are used in between the parenthesis in the “def” header {e.g. def my_function(arg1, arg2)}, but Parameters are used in between the parenthesis when calling the function {e.g. my_function(param1, param2)}.

Thanks for the comments Peter! I had noticed the error in the slide when we released the video, and Dan put up the fixed version, calling the correct my_function(). It somehow reverted back, but should be fixed again.

On the arguments vs parameters, I do see a mix of both used when explaining them, example here on python.org: docs.python.org/3/tutorial/controlflow.html#defining-functions

I agree that the use case you have is solid.

Great tutorial. What is the name of the Terminal you use.

Thanks so much! I’m using Bpython as a REPL (Read, Eval, Print, Loop) tool inside of Visual Studio Code.
