1. Introduction to Python Programming
This introduction tutorial explains the basics of Python programming and its various features. If anyone wants to know what is Python, he really should learn this wonderful programming language and understand its usefulness. In this introduction tutorial, we will comprehensively discuss various features of Python programming that make it popular. Also, we will discuss various filename extensions and Python differences from other programming languages, and most importantly its uses in various fields.
1.1.What is Python Programming?
In this one-stop tutorial, you will first learn about what is Python language. Python is a high-level, general-purpose programming language that has numerous development purposes. We can use it to develop simple applications for complex web services. The simplistic syntax of Python makes it easy to understand and learn for beginners. Moreover, Python supports multiple programming paradigms, including structured, object-oriented, and functional programming. The official logo of Python is shown below.
1.2. Python Example
Below is a simplistic example of Python code that illustrates what and how the code is written in this language. The following code imports the random module of Python and then generates a random number. Finally, this random number is checked to see if it is odd or even.
Example
import random def check_even_odd(number): if number % 2 == 0: return "Even" else: return "Odd" def main(): random_number = random.randint(1, 100) print("Random Number:", random_number) result = check_even_odd(random_number) print("Number is:", result) if __name__ == "__main__": main()
Random Number: 5 Number is: Odd
1.3. Python Filename Extensions
There are many filename extensions that we can use for Python files. Below are some common filenames that we use for Python files.
Extension | Description |
.py | Python script file |
.pyc | Compiled Python file (bytecode) |
.pyd | Python Dynamic Module |
.pyo | Optimized Python file |
.pyw | Python script file for Windows |
.pyx | Cython source file |
.pxd | Cython declaration file |
.pyp | PyInstaller file |
.pyi | Type hinting file |
.ipynb | Jupyter Notebook file |
.pyui | Qt Designer UI files used with PyQt |
