Python Forum

As I understand from a book that function in Python is nothing but object of Function class. I have some doubts as below:

1.When this object gets created? At the time we define function or at the time we call a function?

2.If it is getting created at the time we define a function, then will it not be a waste of memory if we do not call that function anywhere in program ?

Looking for detail answer.

If you're not going to call the function doesn't it make sense not to write it?

The Python interpreter is parsing the whole code from your script or stdin and convert it to bytecode, which runs in the interpreter.

The function object lives in memory at runtime. Yes, if you define it as wasting memory, it is wasting memory. But if you aware of memory you should better use C or assembler.
