What functions are?

Functions in Python are meant to isolate the different parts of the program in smaller chunks.

Functions shall be easy to read and understand.

Let us look at an example

Let us say we want to find the volume of a cube so we write

def volume(side):
    return side*side*side

print(f"The volume of a cube is {volume(3)} cubic cm")
//The volume of a cube is 27 cubic cm

• Here we say that we want to define a function with the keyword def which stands for define in python.
• volume is a name given to that function.
• In parenthesis () we are passing an argument which is of type number.
• And we end the () with : so that the indentation (4 spaces) will begin from the next line.
• return the result with the return keyword.
• We are calling this method inside a print statement where we interpolate the value returned by the function.

Quick gotchas when you are defining a function

• Function name cannot start with numbers or any special characters.
