C. Fill in the blanks.
1. Python module _____is a useful module that enables us to generate random numbers.
2. Functions ceil and floor are available in ______ module of Python.
3. Input arguments specified in a function in an arbitrary order by explicitly associating the names of the formal parameters
with their values are known as __________.
4. A _________ value is used only if the corresponding parameter is not given during the function call.
5. Python module ________ enables us to compute statistical quantities like mean, median, and mode.

D. Answer the following questions:
1. Consider the code given below:
import math
def practice(num):
sq = math.sqrt(num)
print('Square Root is ', sq)
p=49
practice(p)
Identify the following:
a. Name of user defined function
b. Function header
c. Name of built-in function used to find square root
d. Argument(s)
e. Formal parameter(s)
f. Function Body
g. Function Call Statement

Ans. Name of user-defined function : practice
Function header : def practice(num):
Name of built-in function used to find square root : sqrt()
Argument(s): p
Formal parameter(s) : num
Function Body:
sq=math.sqrt(num)
print('Square Root is ',sq)
Function Call Statement: practice(p)
