Differentiate between following with the help of an example: Argument and Parameter, Global and Local variable

Q. Differentiate between following with the help of an example:

(a) Argument and Parameter

(b) Global and Local variable

Answer:-

(a)
Argument: - A value provided to a function in the function call statement.

Parameter: - A name used inside a function to refer to the value which was passed to it as an argument.

For example: -

def addEm(x, y, z):
     print(x + y + z)
addEm(6, 16, 26)

• In the above code, arguments are 6, 16 and 26; and parameter are x, y and z.
