Class statements are sort of... odd. They are code which is directly
executed, and the results are then passed into a
metaclass/type/whatever and a class object is created. While within
the class body, the class doesn't exist yet.
But you don't need it to.
Just do:
'internal_date': print_internal_date
The 'def' is in the same local scope as 'tagdata' is.
Thanks, that worked. But in order to make it work I had to get rid of
'self' in print_internal_date signature, bc all other functions in
tagdata have only a single argument:
class PYFileInfo(FileInfo):
'python file properties'
def print_internal_date(filename):
...
tagdata = {'compiled_fname': lambda x: x + 'c',
'size': os.path.getsize,
'internal_date': print_internal_date
}
That looks weird: a method with no 'self'. Hmm that is probably
seriously wrong.

Absolutely not. It's called a static method, you have to decorate it
with @staticmethod though.
class A:
@staticmethod
def getInstance():
return A()
a = A.getInstance()
you have also the class method version:
class B:
@classmethod:
def getInstance(cls): # class methods take a class as first parameter
return cls()
