So i'm guessing that the attribute has been changed from func_code to
f_code but the inspect module wasn't updated to reflect that.

f_locals doesn't even seem to exist at all.

Please read the documentation for inspect.getargvalues:

"""
inspect.getargvalues(frame)

Get information about arguments passed into a particular frame. A
tuple of four things is returned: (args, varargs, varkw, locals). args
is a list of the argument names (it may contain nested lists). varargs
and varkw are the names of the * and ** arguments or None. locals is
the locals dictionary of the given frame.

Changed in version 2.6: Returns a named tuple ArgInfo(args,
varargs, keywords, locals).
"""

HTH,
Daniel

[...]

I think there are 2 different things :
f_code : 'the code object being executed in this frame'
func_code : 'The code object representing the compiled function'

That is, one is valid in the context of execution stack frames,
while the other is valid in the context of compiled byte code objects
that are generated for functions and so on.

inspect.getargvalues is used on frames, not on regular code objects.
Maybe you were looking for inspect.getargspec?
