Syntax

status = "premium" if total > 100 else "standard"
message = "ok" if response.ok else f"error {response.status_code}"

Best practices

• Keep expressions short; if they span multiple operations, use a full if/else.
• Use parentheses when embedding inside longer expressions for clarity.
• Avoid chaining more than one ternary; readability trumps brevity.
