Binary Search Algorithm
----------------------------------------
The name is evident enough to give an overview of the project.
The program requires you to create a list of numbers between 0
to whatever range you prefer, with every succeeding number having
a difference of 2 between them.
When the user inputs a random number to be searched the program b
egins its search by dividing the list into two halves. The first
half is searched for the required number and if found, the other half
is rejected and vice versa. The search continues until the number is
found or the subarray size becomes zero. This Python project idea could
also help you write a program to search an element in the list.

This python beginner project is a good start for beginner software developers as it has concepts

data as the Mad Libs refer to a series of inputs that a user enters. The input from the user could be
anything from an adjective, a pronoun, or even a verb. After all the inputs are entered the application
takes all the data and arranges it to build a story template.

Number Guessing Game
----------------------------------------
This project is an exciting fun game for beginners to build up. The program generates
a random number from 1 to 10, or 1 to 100 any range that is specified and the user must
guess the number after a hint from the computer. Every time a user’s guess is wrong they
are prompted with more hints to make it easier for them to guess the number but at the
cost of reducing the score. The clue any math clue like multiples, divisible, greater or
smaller, or a combination of all.
The program also requires functions to check if an actual number is entered by the user
or not, to compare the input number with the actual number, to find the difference between
the two numbers.

# Introduction:
Here are programs that every budding programmer who is learning to code in Python should start with. These programs are a compilation of many different types of programs and levels of programming you should try. You can use the table in "Order Of Programs" file to find the order in which it is best to program in.
# Pre-Requisites:
A lot has been said about Python coding and its understandings but before we even start we have to do a little thing there and a little thing there to make it all work seamlessly.
1. Python Interpreter (Pycharm, Visual Studio).
2. Python Environment Container (Anaconda Navigator).
3. A decent laptop/PC to work on with a decent internet connection.

----------------------------------------
Rock Paper Scissors
----------------------------------------
This program or a mini-game is designed when you don’t have anyone
to play or you are under lockdown alone. There are a number of functions
that this program requires so let us have an overview of each.
1. A random function: to generate rock, paper, or scissors.
2. Valid function: to check the validity of the move.
3. Result function: to declare the winner of the round.
4. Scorekeeper: to keep track of the score.
The program requires the user to make the first move before it makes one
the move. Once the move is validated the input is evaluated, the input entered
could be a string or an alphabet. After evaluating the input string a winner
is decided by the result function and the score of the round is updated by the
scorekeeper function.
