Variables in a program include two types: global variables and local variables. Global variables are variables that are defined outside of functions and are valid throughout program execution. A local variable is a variable that is used inside a function, is only valid inside the function, and ...
Defining data types for function parameters and the return value can be used to let user know the expectations of the functions. def prime_numbers(x:int) -> (int, list): l=[] for i in range(x+1): if checkPrime(i): l.append(i) ...
