Programs with Python: Python Examples, Why to Learn, Application of Programs, and Top Recruiting Python Developers

Programs With Python Overview

Programs with Python have always been the Developers' first-choice programming language since its inception. With the flexibility and ease of use it offers, Python has made its name in the IT sector. The Python programming language, created in 1989, was seen as a "gap-filler"—a technique to quickly prototype programs that will be realized in other languages. It has become one of the most widely used languages in the IT industry because of its comprehensible syntax and wide range of features.

What is Python Language?

Python is an interpreted high-level programming language, developed in 1989, that prioritizes code clarity and ease of use. Its origin is traced back to the late 1980s. This programming language was founded by Guido van Rossum, a Netherlands computer scientist who set out to respond to the limitations of existing programming languages. The vision to create a language that prioritizes readability, ease of use, and the ability to speak more complicated ideas with less code was the driving force behind Python's creation. Although ABC was intended to be a language for beginners, its adoption was hampered by certain issues. Guido set out to overcome these constraints and design a language that integrated the most advantageous aspects of already-existing languages while doing away with their intricacies.

Current Significance of Programs with Python

Programs with Python have always attracted not only beginners but also professionals because of their simplicity. However, in today’s time, it has expanded its reach in other sectors too. Currently, It is being used in various sectors such as Big data Analytics, Artificial Intelligence, and many more. Being used by almost every big tech-giant organization like Google, Facebook, IBM, Microsoft, etc. It has broadened its application in many sectors apart from just programming languages. Some of the applications of Python programming languages, due to its huge collection of standard libraries, can be seen in-

1. Machine Learning
2. GUI Applications
3. Image processing (like OpenCV, Pillow)
4. Web scraping (like Scrapy, BeautifulSoup, and Selenium)
5. Test frameworks
6. Multimedia
7. Scientific computing
8. Web frameworks like Django

What is Programming with Python?

Python allows Object-Oriented and Procedural paradigms programming. It allows you to write command-line and cross-platform GUI apps and distribute them as self-contained executables. Although it cannot produce a standalone binary from a script, third-party packages can be used to do so. Unlike some other programming languages, which may look confusing to beginners, Python's syntax is like normal language, making it approachable even to individuals who are new to coding. Its straightforward language framework has made it understandable and easy to write on it. Python is an open-source programming language. Code reliability and maintainability are important while programming in Python. This helps the developers to understand the code even if it was written by some other developer.

Programs with Python: Basic Syntax

Programs with Python are easy and do not require semicolons and braces while writing code on it. However, it uses indentation, which is the white space added in the statement when needed, to define a block of code. Unlike other programming languages, where a statement ends with a semicolon, Python uses a Newline character. Anyways, programming with Python requires some focus while writing any code. Being a case-sensitive language, it treats uppercase and lowercase differently unlike JAVA. Python performs a given function by using a set of keywords such as ‘if’, ‘while’, ‘otherwise’, etc. Such terms are not permitted to be utilized as variables. When these keywords are utilized in writing code outside of their actual or logical requirements, the interpreter rejects the program. These keywords are embedded with specific jobs to execute. The following are some of the examples-

def ():

     print (“hello world”)

     if condition:

          statement 1

     else

          statement 2

statement

This is an example of Python's usage of Newlines to end a statement instead of using semicolons and braces. However, the interpreter understands the program differently.

For example,

Code Block 1 Begins

     Code Block 1 Continues

     Code Block 2 Begins

          Code Block 3 Begins

     Code Block 2 Continues

          Code Block 3 Continues

Code Block 1 Continues

Examples of Python Programs

Python has one of the most straightforward syntaxes when compared to other languages, necessitating fewer lines of code to complete a given task. As a result, learning the fundamentals and understanding the language in a shorter amount of time is made easy. These programs provide illustrative case studies, demonstrating Python's applicability to a range of applications and contexts, which are as follows- 

Basic Programming with Python

Python Program to print “Hello, World!”

print("Hello, World!")

Python Program to build “Calculator”

num1 = float(input("Enter the first number: "))

num2 = float(input("Enter the second number: "))

operator = input("Enter an operator (+, -, *, /): ")

if operator == "+":

    result = num1 + num2

elif operator == "-":

    result = num1 - num2

elif operator == "*":

    result = num1 * num2

elif operator == "/":

    result = num1 / num2

else:

    result = "Invalid operator"

print("Result:", result)

A simple calculator program that takes two numbers and an operator as input and performs the corresponding arithmetic operation.

Python Program for Fibonacci Series

def fibonacci(n):

    if n <= 0:

        return []

    elif n == 1:

        return [0]

    elif n == 2:

        return [0, 1]

    fib_series = [0, 1]

    for i in range(2, n):

        next_fib = fib_series[i - 1] + fib_series[i - 2]

        fib_series.append(next_fib) 

    return fib_series

n = int(input("Enter the number of Fibonacci terms: "))

print("Fibonacci Series:", Fibonacci (n))

A program that generates the Fibonacci series up to a given number of terms. Fibonacci series is a set of infinite numbers, starting with 0 and 1, in which the current number is the sum of two numbers preceding it. For example-

1,1,2,3,5,8,13,21,34,55, etc.

0+1=1

1+1=2

2+1=3

3+2=5

5+3=8

8+5=13

13+8=21 etc.  

To-Do List

tasks = []

def add_task(task):

    tasks.append(task)

    print("Task added:", task)

def show_tasks():

    print("To-Do List:")

    for index, task in enumerate(tasks, start=1):

        print(f"{index}. {task}")

while True:

    print("\nOptions:")

    print("1. Add Task")

    print("2. Show Tasks")

    print("3. Quit")

    choice = input("Enter your choice: ") 

    if choice == "1":

        new_task = input("Enter the task: ")

        add_task(new_task)

    elif choice == "2":

        show_tasks()

    elif choice == "3":

        print("Goodbye!")

        break

    else:

        print("Invalid choice. Please choose again.")

A simple command-line to-do list application that allows users to add tasks and view their tasks.

Web Scraping

import requests

from bs4 import BeautifulSoup

url = "https://www.example.com"

response = requests.get(URL)

soup = BeautifulSoup(response.content, "html.parser")

title = soup. title.text

print("Title:", title)

A program that uses the requests library and BeautifulSoup to perform web scraping, extracting the title of a webpage.

Core Features of Programs with Python

Python has various core features encapsulated in its code and can be accessed when needed, which are as followed-

Automatic Memory Management

One of the most extensive and important features of Python is its Automatic Memory Management. Let’s understand it thoroughly. As we know, everything in Python is an object. These objects are allocated with memory and deallocated when not in use. However, in other languages, these tasks are performed manually and the developers have to do it themselves. But in Python, it is automated and thus reduces the chances of memory-related errors.

Dynamic Typing

In various other programming languages, for example, JAVA, the data types are assigned to variables during the compilation of the program. Whereas, in Python, variables are not bound to any specific datatype when declared. The value of the variable is assigned dynamically during runtime. Thus making it easier for the programmer and does not require to declare variables before using them in the code.

Ease Of Use and Readability

Being an “English-Like language” of Python Programming makes it easier for developers especially for beginners to understand the code easily. The platform offers a clean and consistent code-writing experience which makes it easy to understandable. However, on the other hand, the readability it provides helps reduce the learning curve of the starters. It also results in the enhancement of collaborations among the developers.

Extensive Standard Library

Python's extensive standard library contains about 200 core modules or various tasks. The pre-built functions and modules can be utilized by developers whether pro or beginner. It is one of the most important features of Python, without it, the developers can’t have access to its functionality.

High-Level Data Structures

Python has 4 non- primitive inbuilt data structures named lists, tuples, dictionaries, and sets. It allows its users to have full control over the functionality as it allows them to create their data structures. These data structures are designed to withstand the program's complex data arrangements and operations efficiently.

Interpreted Language

Python is an interpreted language, programs written in it are first translated into bytecode and then run by its virtual machine. The code is simply executed line by line without the requirement for compilation. This leads to shorter development cycles, which makes it easier for developers to see the outcome right away. The ability for the same code to run across other platforms makes cross-platform programming simpler as well.
