Which function would you use to convert a number to an integer in Python?

• A. float()
• B. str()
• C. int()
• D. bool()

Answer: (C)

The function used to convert a number to an integer in Python is int(). When you call this function with a number or a string representing a number, it will return its integer equivalent. For example, if you provide the function with a floating-point number like 3.75, int(3.75) will return 3, effectively truncating the decimal portion.

The int() function is specifically designed for this purpose, making it straightforward to convert various types of numeric data into integers, which can be particularly useful when performing calculations that require whole numbers or when working with data types that need to correspond to integer constraints.

In contrast, the function float() is intended for converting values to floating-point numbers, str() converts values to strings, and bool() converts values to Boolean values (True or False). Each of these functions has its specific use cases, but they do not perform the task of converting to an integer.
