Python Basic Syntax

Python syntax is clear and easy to understand. The language's syntax encourages programmers to write clean, readable code.

# This is a comment
    print("Hello, world!")  # This is a print statement
    

Variables, Data Types, and Operators

In Python, you don't need to declare variables before using them. Python supports several data types, including integers, float, strings, and boolean.

# Variables and Data types
    my_int = 7
    my_float = 1.23
    my_string = "Python is great"
    my_bool = True
    

Python supports various operators like arithmetic, comparison, assignment, logical, identity, membership, and bitwise operators.

Control Structures

Control structures, like if statements and loops, help control the flow of your Python programs.

# if statement example
    if my_int > 10:
        print("my_int is greater than 10")
    else:
        print("my_int is not greater than 10")

    # for loop example
    for i in range(5):
        print(i)
    

Functions in Python

A function is a block of reusable code that performs a specific action. Once a function is defined, it can be used repeatedly in your code.

# Defining a function
    def greet():
        print("Hello, world!")

    # Calling the function
    greet()
    

Python Libraries

Python has a rich collection of libraries that can be used to perform various tasks. Libraries like NumPy, Pandas, and Matplotlib are very popular for data analysis and visualization.

# Importing a library
    import numpy as np

    # Using a function from the library
    array = np.array([1, 2, 3, 4, 5])
