Introduction to Python

At first, Python is a universally interpreted, interactive, object-oriented, high-level programming language. Then, it was developed by Guido van Rossum between 1985 and 1990. As well as Perl, the Python source code is available under the GNU General Public License (GPL). Finally, This Python tutorial helps you to have a good understanding of the Python programming language.

What is Python?

Python is a popular, dynamic, high-level, interpreted programming language. Then, It supports an object-oriented programming approach for developing applications. It’s simple, easy to learn, and has many high-level data structures. Python is easy to learn, but it’s a powerful and versatile scripting language that makes it attractive for application development.
It was only considered useful for automating tedious things, but it quickly became apparent for its versatility. Python is different from dedicated languages ​​such as HTML / CSS, Ruby, and PHP.
Python is also a cross-platform compatible language. So what does that mean? Well, you can install and run Python on multiple operating systems. Whether you’re using Windows, Mac, or Linux, you can rest assured that Python works on all of these operating systems.

Java vs Python Program

Learning the Python programming language is fun. If you compare Python to another language such as Java or C ++, you’ll find that the syntax is much simpler. Also, don’t worry about the lack of a semicolon (;) at the end.
Suppose you want to print “Welcome to eMexo Technologies” on your screen. Let’s compare the syntax of Python and Java.

Java Program

public class eMexo {  
 public static void main(String[] args){  
// Prints "Welcome to eMexo Technologies" to the terminal window.  
  System.out.println("Welcome to eMexo Technologies");  
 }  
 }  

Python Program

On the other hand, we can do this using one statement in Python.

print("Welcome to eMexo technologies")

Both programs return the same result, but Python requires only one statement without the use of semicolons or braces.

Reasons to learn Python

Python provides programmers with many useful functions. These features make it the most popular and widely used language. Below are some important features of Python.

• Easy to use and Learn
• Expressive Language
• Interpreted Language
• Object-Oriented Language
• Open Source Language
• Extensible
• Learn Standard Library
• GUI Programming Support
• Integrated
• Embeddable
• Dynamic Memory Allocation
• Wide Range of Libraries and Frameworks

What are the areas in which python gets used?

Python is a universal and popular programming language used in almost every technical field. The various areas that use Python are listed below.

• Data Science
• Data Mining
• Desktop Applications
• Console-based Applications
• Mobile Applications
• Machine Learning
• Computer Vision or Image Processing Applications
• Software Development
• Artificial Intelligence
• Web Applications
• Enterprise Applications
• 3D CAD Applications
• Speech Recognition

Popular Python frameworks and libraries

At first, Python has a wide range of libraries and frameworks that are widely used in a variety of areas, including machine learning, artificial intelligence, and web applications. Finally, We define some common Python frameworks and libraries as follows:

• Web development (Server-side) – Django Flask, Pyramid, CherryPy
• GUIs-based applications – Tk, PyGTK, PyQt, PyJs, etc.
• Machine Learning – TensorFlow, PyTorch, Scikit-Learn, Matplotlib, Scipy, etc.
• Mathematics – Numpy, Pandas, etc.

Example of Python Program

Now that you’ve learned what Python is and what you can do with Python, let’s write a simple Python program to harness your knowledge.
Take a look at the Python program in this example-
Problem-Create a Python program that gets two numbers from the user and outputs their sum.

Code:

#To find sum of 2 numbers
num1=int(input("Enter the 1st number:"))
num2=int(input("Enter the 2nd number:"))
sum=num1+num2
print("The sum of the 2 numbers is",sum)

• In the code snippet above, I used Python’s “input” function to get two numbers from the user and calculate the sum.
• Then I used the “Print” feature to display the totals.
• I also added related comments.

Career Opportunities:

Python has great career opportunities in the IT industry. Almost every other IT company, be it a start-up or a multinational company, uses Python for a variety of applications. Therefore, if you have a good knowledge of Python, you will have to do different jobs in different areas such as machine learning, cloud infrastructure, website design, and testing.
