Best 8 Python Programs for Beginners

Python is a powerful and easy-to-use programming language that can be used for a wide range of tasks. It has a very simple syntax, which makes it easy to learn for beginners, and it has a very large community of developers who develop libraries and tools for a wide range of tasks to make many jobs easier. 

So in today’s article, we will go through some basic Python programs for beginners to level up their coding skills.

Understanding Python Variables.

Before we start writing Python programs, it is very important to understand the concept of a variable in Python. In Python, variables are just like containers that store something inside them, which means variables are used to store the values in Python that can be changed or modified later in the program.

To make a variable in Python, simply assign the value to the name. An example is given below

name = "John"
age = 25

Here, John is a name, which is stored in the name variable. In Python, the operator “=” is used to assign a value to the variable. Like John, 25 is stored in the age variable.

Note: In Python words, letters or sentences are string which is always written inside the single or double quotations

Simple Calculations with Python

Arithmetic is one of the basic operations that can be performed in Python. To perform arithmetic operations, we can use the “+” sign for addition, the “-” sign for subtraction, the “*”” sign for multiplication, and the “/  ”’ sign for division. 

a = 7
b = 5
c = a + b
print(c) # Output: 8

Taking User Input

In many programs, it is very important to accept user inputs. This allows programmers to develop interactive programs that can respond to user input. To take the user input in python, you can use an input() function. For Example

name = input("What's your name? ")

print("Hello, " + name + "!")

Note: input( ) function always takes the value as a string data type, so if you want to do some calculator or arithmetic operation, So you need to change the data type of the variable

Arithmetic Operation using user input

This is a simple combination of previous both examples, where we perform the arithmetic operation by accepting users’ inputs.

number1  = int(input(“type the first number”))
number2  = int(input(“type the second number”))
add = number1 + number2
print(“Addition of “, number1, “ and “, number2, “ is:  ”, add)

Using Conditional Statements

In Python Conditional Statements allow you to execute the different blocks of code based on specific criteria/conditions. For Example, You want to select those students whose age is 18 or more.

This means there is an if condition statement that checks whether the age of the student is 18 or not. If yes then the program shows a success message on completion of that criteria 

age = 25
if age >= 18:
  print("You are an adult.")
else:
  print("You are not an adult.")

Working with Loops

In Python, loops are used for the repetition of code until a specific criterion is met. There are two types of loops: for loops and while loops. 

• While loops are used to repeat a block of code as long as a certain condition is true,
• whereas For loops are used to iterate over a sequence of values, such as a list or a string. 

For example:

# For loop
fruits = ["apple", "banana", "cherry"]
for fruit in fruits:
  print(fruit)

# While loop
count = 1
while count <= 5:
  print(count)
  count += 1

Defining Functions:

A function is similar to a collection of code or a block of code that can be called repeatedly in the program. Functions can take arguments and return values. This allows users to reuse the code without having to write it multiple times in your program.

In Python, there are two types of function

1. Built-in Function: those function which comes with python like print( ) function, len( ) function, and many more
2. User Defined Functions:  those functions which are created by users by themselves.

In order to create a user-defined function, we use the def keyword and then name it with parentheses, just like below.

def greet(name):
  print("Hello, " + name + "!")

greet("John") # Output: Hello, John!

Importing Modules

Python has a very large number of libraries or modules that can be used in programs. Those modules provide some additional functionality that makes programs more powerful and efficient.

For example, you can use the “math” Library for mathematical operations such as square root or logarithm.

For Example.

import math
x = math.sqrt(16)

print(x)  # output will be 4

Here in the math module, “sqrt” is a function that is used to get the square root of a number.

Final Verdict

There are just a few basic Python programs for beginners to level up their coding skills. With the help of these python programs, you can create your own more complex and powerful python programs. Always remember that practice, experimentation, and keeping learning are the keys to success. So there are a lot of online resources available, including tutorials, forums, and books which can help you to continue your journey to learn python programming
