Answer:
Example 1:
def function(num):  
    print(num*2)
Example 2:
function(5)
num = 2
function(num)
function(3-1)
Explanation:
Given:
See attachment for complete question
To start with Example (1)
def function(num):  
    print(num*2)
<em>Note that; the above code segment which doubles the parameter, num could have been any other code</em>
<em />
<em>In Example (1), the parameter is num</em>
For example (2):
We can call the function using:
#1. A value:
function(5)
<em>In #1, the argument is 5; a value</em>
#2. A Variable
num = 2
function(num)
<em>In #2, the argument is num; a variable</em>
#3. An Expression
function(3-1)
<em>In #3, the argument is 3-1; an expression</em>
