Functions

A function is a block of organized, self-contained programs that perform a specific task, which you can incorporate into your own larger programs. They are defined as follows:

    # function 
    def  functionname(): 
      do something 
      return 

These are a few points to remember:

• Indentation is very important in Python programs
• By default, parameters have a positional behavior, and you need to inform them in the same order that they were defined in

Please see the following code snippet example, which showcases functions:

    def display ( name ): 
    #This prints a passed string into this function 
      print ("Hello" + name) 
      return;

You can call the preceding function as follows:

    display("Manish") 
    display("Mohit") 

The following screenshot shows the execution of the preceding display function:
