The following works. But I've no idea how to pass params to the member
function. (Anyone: How can you call a function with parameters unpacked from
a tuple??)
But why do you actually want to do this? If the class instance is not
important, just make a static method of this one.
class RT(object):
def Evaluate(self, code):
def generateContext():
def dropself(f):
def g(*p):
f(self)
return g
context = {}
for f in RT.__dict__:
context[f] = dropself(RT.__dict__[f])
return context
eval(code, generateContext())
def test(self):
print 'RT test'
RT().Evaluate('test()')
