You need to use the "global" statement on AYS to prevent it from being
shadowed by the local namespace in the functions. So something like the
following will work for you:

>>> a = '' 
>>> def setEnvironment(): 
...     global a 
...     a = 'number9'
... 
>>> def getEnvironment(): 
...     global a 
...     return a 
... 
>>> getEnvironment() 
'' 
>>> setEnvironment() 
>>> getEnvironment() 
'number9'
