Python if Statement Practice Questions for Beginners

Chapter 8 Recap and Practice

Your programs can now make decisions. Here is the chapter in one table:

You write	It does
`if age >= 18:`	runs the indented block only when the condition is `True`
4 spaces	the indentation that marks a block; it must line up exactly
`else:`	the other path, when the condition is `False`
`elif marks >= 75:`	another condition; only the first `True` one runs
`a and b`	`True` only when both are `True`
`a or b`	`True` when at least one is `True`; write both comparisons in full
`not a`	flips `True` and `False`
`(a and b) or c`	brackets show which parts go together
an `if` inside an `if`	a nested if: a second question after a yes
`if b != 0:`	check input before you use it

And the checklist when an if misbehaves: == not =, the colon, the indentation, numbers converted with int(), and the order of your elifs.

Practice questions

Use input() with no prompt text. The tests try several inputs, including the edges (like exactly 18, or exactly 100), so test your program with those too.
