Multiple Statements in Python

Python allows you to write multiple statements on a single line or group them into code blocks called suites. This flexibility helps organize your code efficiently.

Multiple Statements on a Single Line

The semicolon (;) allows multiple statements on the same line, provided that neither statement starts a new code block ?

import sys; x = 'foo'; sys.stdout.write(x + '\n')

foo

Example with Variables

You can assign multiple variables and perform operations on a single line ?

a = 5; b = 10; result = a + b; print(result)

15

Multiple Statement Groups as Suites

A group of individual statements that make a single code block are called suites in Python. Compound statements like if, while, def, and class require a header line and a suite.

Header lines begin with a keyword and terminate with a colon (:), followed by one or more indented lines that make up the suite ?

if expression:
    suite
elif expression:
    suite
else:
    suite

Example with if Statement

age = 18

if age >= 18:
    print("You are an adult")
    print("You can vote")
else:
    print("You are a minor")
    print("You cannot vote yet")

You are an adult
You can vote

Example with Function Definition

def calculate_area(length, width):
    area = length * width
    return area

result = calculate_area(5, 3)
print(f"Area: {result}")

Area: 15

Key Points

• Use semicolons to separate multiple statements on one line
• Suites are indented code blocks following a colon
• Python uses indentation to define code blocks, not braces
• Compound statements require proper indentation for their suites

Conclusion

Python's semicolon syntax allows compact single-line statements, while suites provide structured code blocks. Proper indentation is essential for defining suites in compound statements.
