Why Does Inspect.getsource Throw Typeerror When Trying To Get Source For Python Built-in?

What is the difference between a python built-in and a normal object? we often say that in python everything is an object. for example, when I do this in Python 3.6: >>>

Solution 1:

You can't access the source of builtins and other modules that were written using the C API, since there isn't a Python source for them.

From the documentation for os.getsourcefile

Return the name of the Python source file in which an object was defined. This will fail with a TypeError if the object is a built-in module, class, or function.
