How can I get the int(), float(), dict(), etc. callables from their names? For example, I'm trying to save Python values to xml and storing the variable type as a string. Is there a way to get the callable from the string when converting from string back to the Python type?
Normally I would do something like getattr(myobj, 'str'), but there is no module to use as the first argument for these built-in conversion functions. I've also tried getattr(object, 'str'), but this doesn't work either since these functions are not part of the base 'object' type, merely globals to the language.

The built-in function dir() returns a list of names of attributes, methods, etc. of the object specified in the argument. You can get a list of names of built-in objects, such as built-in functions and constants, by passing the builtins module or __builtins__ to dir() . To make the output easier to read, use pprint.
Built-in functions are ones for which the compiler generates inline code at compile time. Every call to a built-in function eliminates a runtime call to the function having the same name in the dynamic library.
Solution 1. Please try solution from below , as there is no in built equivalent fucntion for Val() in Python .
You have already used some of the Python built-in functions, for example, the print() function is used to output a string on the console. As of now, the latest version of Python 3.8 has 69 built-in functions.

Wrong, there is:
import __builtin__
my_str = getattr(__builtin__, "str")
(In Python 3.x: import builtins)
