So you want the user to input the name of a class and you create an
instance of the class? Try
cls = getattr(yeast_cell, zz)
instance = cls()

This is just assigning a class variable. The assignment is made at the
time the class is defined, not when an instance is created, so that is
not what you want either.

I agree with John that changing a global variable in another module when
a class instance is created doesn't seem like a great design, but you
can do it here with
import main # or whatever the main module is called
main.YEAST = 'G'
In general it is good to avoid circular dependencies like this, they
lead to a variety of complications. Maybe YEAST could be a variable in
the yeast_cell module?
