how to create local dynamic varables
- by xielingyun
this is my code, i want to use eval() to get the rule status and eval() nead local varables, there is many classes inherit class base, so i should to rewrite get_stat() in every class.i just want to avoid this, an idea is to create dynamic varables in get_stat(),eg. in class b it dynamic create var a and b
how to create dynamic varables in function? or any other way to avoid this stupid idea
i use python 3.2.3, locals() does not work
class base(object):
def check(self):
stat = get_stat()
def get_stat(self):
pass
class b(base):
rule = 'a > 5 and b < 3'
a = 0
b = 0
def update_data(self, a, b):
self.a = a
self.b = b
def get_stat(self):
a = self.a
b = self.b
return eval(rule)
class b(base):
rule = 'd > 5 and e < 3'
d = 0
e = 0
def update_data(self, d, e):
self.d = d
self.e = e
def get_stat(self):
d = self.d
e = self.e
return eval(rule)
