Python

Python is a high-level programming language that has gained popularity due to its simple and easy-to-learn syntax, as well as its powerful capabilities. It is widely used in various fields such as data analysis, artificial intelligence, and web development.

Advantages of Python

• Easy to Learn: Python’s syntax is clear and concise, making it highly readable and suitable for beginners.
• Powerful Library Support: Python has a rich ecosystem of third-party libraries, such as NumPy, Pandas, and Matplotlib, which make data processing and analysis more efficient.
• Cross-Platform: Python can run on multiple operating systems, including Windows, macOS, and Linux.

Basic Syntax

Variables

In Python, variables do not require type declaration; you can simply assign values to them.

x = 5
y = "Hello, World!"

Data Types

Python supports various data types, including integers, floating-point numbers, strings, and boolean values.

integer_var = 10          # Integer
float_var = 10.5         # Float
string_var = "Python"     # String
boolean_var = True        # Boolean

Control Structures

Python uses indentation to define code blocks, and control structures include conditional statements and loops.

Conditional Statements

if x > 0:
    print("x is positive")
else:
    print("x is non-positive")

Loops

for i in range(5):
    print(i)  # Output: 01234

Functions

Functions are the basic building blocks of Python and can be defined using the def keyword.

def greet(name):
    return f"Hello, {name}!"

print(greet("Alice"))  # Output: Hello, Alice!
