Calling a Function

Calling a Function

To call the hello() function from example 7.2-1, you use this code:

When you call the “hello()” function, the program displays the following string as output:

Output

hello – Python

Alternatively we can call the “hello()” function within the print() function as in the example given below.

Example:

def hello():

print (“hello - Python”)

return

print (hello())

If the return has no argument, “None” will be displayed as the last statement of the output.

The above function will output the following.

Output:

hello – Python

None
