Basic Python Syntax and Data Types 📝: Writing Your First Code

Intermediate

Understanding Python syntax and data types is fundamental. Python uses indentation to define code blocks, simplifying readability.

Hello World!

print('Hello, World!')

This prints a simple message to the console.

Variables and Data Types:

  • Integers: x = 5
  • Floats: pi = 3.14
  • Strings: name = 'Alice'
  • Booleans: is_valid = True

Type Checking:

type(x)  # Output: <class 'int'>

Comments: Use # for single-line comments.

# This initializes an age variable
age = 30

Basic Operations:

sum = 10 + 5
diff = 10 - 5
prod = 10 * 5
quot = 10 / 5  # Always float division

# Integer division
div_int = 10 // 3  # Result: 3

# Modulo (remainder)
remainder = 10 % 3  # Result: 1

Mastering syntax and data types is crucial to write effective Python code that is clear and efficient.
