Review your knowledge of Python if‑elif‑else conditional statements with structured questions. Great for beginners preparing for exams, quizzes, or coding interviews.
The 'if' statement is used for conditional execution. It evaluates a condition and executes its block of code only if the condition is True.

'elif' should be used when checking multiple exclusive conditions where only one block should execute. Separate 'if' statements check independently and multiple blocks could execute.
📘 Related Topics:
The 'else' clause provides a default block of code that executes when all preceding 'if' and 'elif' conditions evaluate to False.
📘 Related Topics:
A nested conditional is an 'if' statement inside another 'if' statement. It's used when you need to check additional conditions only after a primary condition is met.

Python evaluates conditions from top to bottom. It executes the first block where the condition is True, skips all remaining conditions, and executes the 'else' block only if all conditions were False.

Common mistakes include: 1. Forgetting colons after conditions 2. Using assignment (=) instead of comparison (==) 3. Incorrect indentation of blocks 4. Over-nesting conditionals unnecessarily 5. Not covering all possible cases

Use logical operators: 'and' (both true), 'or' (either true), 'not' (inverse). Parentheses can group conditions for clarity and proper evaluation order.
