Hi,
I would like to define methods using exec like this:
class A:
def __init__(self):
cmd = "def sqr(self, x):\n return x**2\nself.sqr = sqr\n"
exec cmd
a = A()
print a.sqr(a, 2)
This works, but I have to call sqr with a.sqr(a, 2), a.sqr(2) does not work
(TypeError: sqr() takes exactly 2 arguments (1 given)).
Is there a possibility to define methods using exec and getting normal behavior?
I would be very appreciative for any help.
With kind regards
Rolf Wester
