What is Python?
Python is a high-level, interpreted programming language known for its simplicity and readability. It was created by Guido van Rossum and released in 1991. Python supports multiple programming paradigms, including procedural, object-oriented, and functional programming. It is widely used for web development, data analysis, artificial intelligence, and scientific computing.
Python Syntax
Python uses indentation to define code blocks, making it easy to read and understand. Variables do not need to be explicitly declared, and data types are dynamically assigned. Python uses the ‘#’ symbol for comments. Python functions are defined using the ‘def’ keyword, and indentation is used to define the function body.
Example Codes
- Hello World:
1
print("Hello, World!")
This simple code displays the text “Hello, World!” on the screen.
- Variables and Data Types:
1 2 3 4
x = 10 y = "Python" print(x) print(y)
In this code snippet, we initialize variables ‘x’ with the integer value 10 and ‘y’ with the string “Python” and then print their values.
- Conditional Statements:
1 2 3 4 5
x = 10 if x > 5: print("x is greater than 5") else: print("x is less than or equal to 5")
This code demonstrates a simple if-else statement in Python based on the value of variable ‘x’.
Python Versions
Python has two major versions: Python 2 and Python 3. Python 2 was the legacy version, but its support ended in 2020. Python 3 is the current and future of the language, with many improvements and features compared to Python 2. As of now, Python 3.9 is the latest stable release, with ongoing developments and updates.
Overall, Python is a versatile and powerful programming language that is popular among developers for its simplicity, readability, and vast ecosystem of libraries and frameworks. Its easy syntax and dynamic typing make it a great choice for beginners and experienced programmers alike. Start your Python journey today and discover the endless possibilities it offers.
