Why not just use update()?

In [11]: class TestClass:
   ....:     def __init__(self):
   ....:         self.var1 = 0
   ....:         self.x = 0
   ....:         self.size = 0
   ....:

In [12]: tc = TestClass()

In [13]: tc.__dict__
Out[13]: {'x': 0, 'var1': 0, 'size': 0}

In [14]: tc.__dict__.update({'x': 'this is x', 'var1': 'this is var1', 
'size': 125})

In [15]: tc.var1
Out[15]: 'this is var1'

In [16]: tc.x
Out[16]: 'this is x'

In [17]: tc.size
Out[17]: 125
