This function, input_float, prompts the user for input and ensures that the entered value can be successfully converted to a float. Here's a step-by-step explanation of what it does:

1. The function accepts one argument, prompt (a string), which is the message displayed to the user when requesting input.

2. Inside a while True loop, the function repeatedly asks the user to provide input:

   • It displays the prompt message followed by a colon (:) using input.
   • It waits for the user to enter a value.

3. It attempts to convert the user's input to a float using float(value) inside a try block:

   • If successful, it immediately returns the converted float value, exiting the function.
   • If the conversion fails (e.g., the user enters invalid input like "abc"), a ValueError is raised.

4. If a ValueError exception occurs (invalid input), the function catches it in the except block and prints the message: "invalid input. Please enter a number".

5. The while True loop ensures the function repeatedly asks for valid input until the user provides a value that can be converted to a float.

Example usage:

age = input_float("Enter your age")
print(f"Your age is {age}")

• If the user enters: abc, the program prints: invalid input. Please enter a number, and re-prompts.
• If the user enters: 25.5, the function returns 25.5 as a float, and the program proceeds.

This ensures robust handling of user input by requiring valid numeric input before proceeding.
