A software library contains procedures that can be used in the creation of new programs.
Existing segments of code can come from internal or external sources, ie. libraries or previously written code.
The use of libraries simplifies the task of creating complex programs.
Application program interfaces (APIs) are specifications for how the procedures in a library behave and can be used.
Documentation for a library or API is necessary in understanding the key behaviors provided by the API/library and how to utilize them in your work.

A library is a collection of code from an external source that can be used to add functionality to a program.
Libraries are very useful, as they can be used to save time and effort in the development process.
Libraries are usually included in a program using a special keyword called "import" This keyword tells the program to look for the library and use its code.

1) Randomization generates a value between two numbers. For example RANDOM(1,3) may result as 1 or 2 or 3, either one of those.

2) Now if we look into our day to day life we can see that randomization is all around us.

import random

answer1 = random.randint(0,3)
answer2 = random.randint(1,8)
answer3 = answer1 + answer2
print(answer3)

Use "Pip install ___" for new libraries

import random

num = random.randint(1,2)

if num == 1:
    print("Head")
elif num == 2:
    print("Tails")
