[Type B] Working with Functions – Chapter 3 Sumita Arora

3. Consider the following code and write the flow of execution for this. Line numbers have been given for your reference.

def power(b, p):
    y = b ** p
    return y

def calcSquare(x):
    a = power(x, 2)
    return a

n = 5
result = calcSquare(n)
print(result)

Solution:

1. power function is defined.
2. calcSquare function is defined.
3. n is assigned the value 5.
4. calcSquare function is called with argument n.
5. Inside calcSquare, power function is called with arguments x and 2.
6. power function calculates the square of x.
7. The result is returned and assigned to result.
8. result is printed.

In short, flow of execution is as follows:

1. Define power function.
2. Define calcSquare function.
3. Assign n = 5.
4. Calculate square of n using calcSquare.
5. Print the result.
