Why this matters
Assertions can be disabled in production, meaning critical checks might not run. Use explicit validation with exceptions to ensure errors are handled properly.
assert for Data ValidationEnsure that assert is not used for validating user input or critical checks. Assertions can be disabled in optimized mode (python -O). Recommend using explicit validation with if conditions and raising proper exceptions.

Side-by-side examples engineers can pattern-match during review.
assert x > 0, 'x must be positive'if x <= 0:
raise ValueError('x must be positive')From the same buckets as this rule.
Check if loops use equality operators (== or !=) in termination conditions. These can lead to infinite loops if the condition is never met exactly. Instead, use relational operators like < or > for safer loop termination.
