Functions

Defining a basic function

def functionName(int)
  sum = int + 2
  return sum

Calling a basic function

functionName(int)

Function arguments

All function arguments are passed by reference. It means if you change what a parameter refers to within a function, the change also reflects back in the calling function.

Function argument types

• Required arguments
• Keyword arguments
• Default arguments
• Variable-length arguments

Required arguments

Mandatory arguments that have to be passed to the function.

def functionName(int)
  sum = int + 2
  return sum

Keyword arguments

def functionName(name, value)
  sum = int + 2
  return sum
  
functionName(value = 24, name = 'tralala')

Default arguments

Non mandatory arguments that default to a specified value.

def functionName(int = 1)
  sum = int + 2
  return sum

Variable-length arguments
