What syntax is used to convert an input from string to float?

The conversion of input from a string to a float in Python is achieved using the float() function applied to the input(). When you call input(), it reads user input as a string. To convert this string representation of a number into a floating-point number, you encapsulate the input() function with the float() function.

When you use float(input()), the process works as follows:

1. The input() function prompts the user and waits for their input, capturing it as a string.

2. The float() function then takes this string as an argument and converts it to a float, assuming the input is a valid numeric representation (such as "3.14" or "2.0").

This is essential in scenarios where mathematical operations involving decimal numbers need to be performed. If the user enters an input that cannot be converted to a float (like "abc"), a ValueError will be raised.

The other options do not perform the desired task of converting input to float. Utilizing int() would convert the input into an integer instead, while str() merely converts other data types to a string and does not fit the requirement for converting a string to a float. Calling input with a float argument doesn't adhere to the correct function usage in Python, as input
