Need to call class method from different class without initialization of the first class or some other way around it
In general you can call a class method from anywhere you want and pass anything to it without initialisation of that class's instance, thanks to objective nature of python, but beware of self dependencies! Although, I don't think that's a good practice.
class A: def __init__(self): self.foo = 'foo' def return_foo(self): return self.fooclass B: def __init__(self): self.bar = 'bar' print('Ha-ha Im inited!') def return_bar(self): try: return self.bar except AttributeError: return 'bar'def test(): a = A() # b = B() return_bar = getattr(B, 'return_bar', None) if callable(return_bar): print('%s%s' % (a.return_foo(), return_bar(None)))test()Links:
