Collect Every Form Error

Medium ⏱ 12 min 57% acceptance ★★★★☆ 4.2

A signup form needs name (non-empty), age (int-parseable, 18+), and email (contains '@'). Write validate(form) — a dict of strings — returning a list of ALL failure messages ('bad name', 'bad age', 'bad email'), not just the first. Use try/except around the age parse; empty list means valid.

Examples

Example 1

Input

validate({'name': '', 'age': 'xx', 'email': 'a@b.c'})

Output

['bad name', 'bad age']

Explanation

Two independent failures are both reported.

Constraints

Report all errors, in name/age/email order.
Age must parse AND be >= 18.

Hints

Hint 1

Each check appends independently — no early return.

Hint 2

The int() call needs its own try/except.
