Creating a Function
We can create a function in the following ways:
Defining a Function: We use the def keyword to begin the function definition.
Naming a Function: Provide a meaningful name to your function.
Parameters: These are the variables given inside the parentheses in the function definition. The
parameters (separated by commas) are given in the parentheses following the name of the function.
Body of the Function: The body of the function contains Python statements that perform the task
or computation for which function is designed for.
Syntax of creating a function is:
def < name of the function > (list of parameters):
<body of a function >
Calling a Function
A function can be called anytime from other functions or from the command prompt after the definition.
For calling a function, we type the function name followed by parentheses containing any required
parameters. For example:
To call a function
def my_function(): Name of a function
print (“Hello”) Body of a function
my_function() Function call
Program 1: To print a string by calling a function
Program1.py
File Edit Format Run Options Window Help
#Function definition
def hello (name):
print('Hello ' +name+ '! How do you do?')
#Calling function by passing parameter
hello('Orange')
You will get the following output:
Output
Hello Orange! How do you do?
