Dunno if there is a better way, but brute force works:

systemvars=globals().copy()
systemvars['systemvars']=systemvars
systemvars['_[1]']=None # comment this and you will discover something 
a=5
b=7
c=9
uservars=dict([slot for slot in globals().items()
               if not slot[0] in systemvars])
print uservars
# => {'a': 5, 'c': 9, 'b': 7}

HTH,
