A map can have any set as its codomain, while, in some contexts, typically in older books, the codomain of a function is specifically the set of real or complex numbers. def fun(): # function definition print ("Hey u called fun()") fun() # calling a function Output : Hey u called fun() The moment fun() is executed, The control goes to function definition.

The value that is returned can be used in an assignment statement or elsewhere in expressions. A function is a subprogram that is used to perform a predefined operation and optionally return a value.Using functions, we can avoid repetitive coding in programs and simplify as well as speed up program development. C++ Function Prototype & Definition Tutorial - In C++, a functions must be defined before it is used anywhere in the program. . Call a function from another function in Python I think the moral of the story is that when you want/need something to execute right now, you call the function.
