How do I validate tuples in Python with examples?

In Python, you can validate tuples by checking their length, data types, or specific values. This can be done using simple conditional statements or more sophisticated methods like defining functions or using libraries like `pydantic`. Here are some examples of validating tuples.

# Example 1: Validating the length of a tuple def validate_tuple_length(tup, expected_length): if len(tup) != expected_length: raise ValueError(f"Tuple must be of length {expected_length}, but got {len(tup)}.") # Testing the function try: validate_tuple_length((1, 2, 3), 3) # Valid validate_tuple_length((1, 2), 3) # Raises ValueError except ValueError as e: print(e) # Example 2: Validating datatypes in a tuple def validate_tuple_types(tup, expected_types): if len(tup) != len(expected_types): raise ValueError("Tuple length and expected types length must match.") for item, expected in zip(tup, expected_types): if not isinstance(item, expected): raise TypeError(f"Expected type {expected} but got {type(item)} for item {item}.") # Testing the function try: validate_tuple_types((1, "string", 3.14), (int, str, float)) # Valid validate_tuple_types((1, 2, 3.14), (int, str, float)) # Raises TypeError except (ValueError, TypeError) as e: print(e)
