When you type ‘import math’ you are importing all functions and classes in the math module but when you type ‘from math import [name of class]’, you only get access to that class in the whole module. you may write this ‘from math import *’ to import everything from the “from” statement

 

Q.15 :What is the utility of random module ?

Answer:

Python Random module is an in-built module of Python which is used to generate random numbers. These are pseudo-random numbers means these are not truly random. This module can be used to perform random actions such as generating random numbers, print random a value for a list or string, etc

 

Q.16 :What is the significance of modules?

Answer:

A module allows you to logically organize your Python code. Grouping related code into a module makes the code easier to understand and use. A module is a Python object with arbitrarily named attributes that you can bind and reference. Simply, a module is a file consisting of Python code.

 

Q.17: What is the role of an argument of a function?

Arguments are inputs to functions; they allow a function to produce different (but appropriate) outputs for different inputs.The terms parameter and argument can be used for the same thing: information that are passed into a function. From a function’s perspective: A parameter is the variable listed inside the parentheses in the function definition. An argument is the value that are sent to the function when it is called.
