Question

What type of exception does a program raise when it uses the float function to convert a non-numeric string to a number?

Short answer

Answer: ValueError

Step-by-step solution

Understand exceptions in Python

Exceptions are events that occur during the execution of a program that disrupt its normal flow. In Python, exceptions are triggered when an error or an exceptional situation occurs, and they are handled using try-except blocks.

Analyze the behavior of the float function

The float() function in Python is used to convert a number or a string to a floating point number. If the input is a non-numeric string, the function will raise an exception.

Identify the type of exception raised

When float() function attempts to convert a non-numeric string to a number, Python raises a ValueError exception. This indicates that the operation has received an inappropriate argument value that it cannot process. Example: ```python try: float("non-numeric string") except ValueError as ve: print("Exception:", ve) ``` Output: ``` Exception: could not convert string to float: 'non-numeric string' ```
