Kubernetes Classroom Series – 21/Sept/2021

Functions

• The first step to code reuse is the function.
• A function is a block of code that can take any number of input parameters and return any number or type of output results
• Define a function with def
  • syntax:

  def <function>(<parameters>):
      pass
  

  • example:

  def add(a, b):
      return a + b
  
  print(add(1,2))
  

  
  • In the function return keyword returns the evaluated result to the caller and it is not necessary that every function needs to have return. The function without return value return None
  • Lets quickly write a program which has some functions
  • Refer Here for the program which has function is_prime and its usage in the same python file (module)
• Lets try to create reusable functions for calculating
  • simple interest
  • compound interest
  • Refer Here for the solution
