Which function in Python can be used to change the type of a value to integer?

Question

BlackTom AI · Accepted Answer

Starting with the goal of converting a value to an integer in Python, we can evaluate each option for its validity.
Option A: cast( ). This resembles a generic naming pattern, but Python does not provide a built-in cast() function for type conversion. The standard type conversion functions have specific names rather than a universal cast.
Option B: None of the others. If there is a valid built-in function among the list that converts to integers, this option would be incorrect. We should verify whether any of the remaining choices actually perform the conversion.
Option C: type( ). The type() function returns the type of an object (e.g., int, str, list), not a conversion. It’s used for introspection, not to cast a value to a different type.
Option D: int( ). This is the canonical built-in that converts a value to an integer, applying numeric conversion rules and raising an error if conversion isn’t possible. This is the standard approach for turning strings like '42' or floats like 3.9 into integers.
In summary, among the provided options, the only function that serves as a conversion to integers is int( ). The other choices either describe a non-existent casting function, perform type introspection, or suggest an incorrect concept for the task at hand.
