What function would you use to display the type of a variable in Python?

The function to display the type of a variable in Python is indeed the type() function. When you call type() and pass a variable as an argument, it returns the type of that variable, which can help you understand what kind of data it holds, such as integer, string, list, etc. This is particularly useful for debugging and ensuring your code behaves as expected, especially when working with dynamic typing where variables can change types during execution.

The other functions listed do not serve this purpose:

• display() is not a built-in function in Python for showing variable types. It might be used in frameworks or libraries, but it is not standard in Python itself.

• print() is used to output data to the console, but it does not specifically return the type of a variable. It can be used in conjunction with type() to output the variable's type, but on its own, it does not provide that functionality.

• show() is similarly not a standard function in Python for determining variable types and does not exist in the core Python language.

Thus, type() is the definitive function to use when you need to ascertain the type of a variable in Python programming.
