Python Indentation

Python diverges significantly from other programming languages in its approach to code grouping. Instead of employing curly braces {} to define blocks of code, Python relies exclusively on indentation (utilizing either spaces or tabs). This practice is not merely a stylistic choice; it is a mandatory syntax requirement.

Example:

# Other languages use {} but Python uses indentation
if age > 18:
    print("You are an adult")   # indented = inside the if block
    print("You can vote")       # still inside
print("This is outside")        # not indented = outside the block

Incorrect indentation will lead to syntax errors and program failure. However, once mastered, this structure ensures the code remains exceptionally clean and readable.
