Imports in python are static, any solution?

[AJ Mayorga]

For something like this I generally create a superclass to hold
configuration variables that will change overtime, doing that will save you
from insanity.

Class configVar:

	#set initial values
	Def __init__(self):
		Self.A = 5
		Self.B = 10
		Self.C = 20


Class myMath(configVars):
	def __init__(self):
		pass

	def SubAandB(self):
		return self.A - self.B

	def AddCandB(self):
		return self.C + self.B

	def MultiplyXbyA(self, x):
		return self.A * x


m = myMath()
X = m.SubAandB()
Y = m.AddCandB()
Z = m.MultiplyXbyA(32)

Keeps your vars in a safer easier to handle, debug, and change kinda way
Good luck

Why not only import foo and using foo.i? In fi() when you set i = 99
you are creating a new object called i in foo's namespace.
