测试例子：

from var_dump import *class A:    def __init__(self,aa,bb):        self.a = aa        self.b = bb    def pa(self):        print(self.a,self.b)class B:    def __init__(self):        self.y = 13423        self.g = ‘sdsdsds‘        self.ob = A(223,454)        a = A(3,4)a = B()var_dump(a)print(‘---------------------‘)s = var_dump_s(a)print(s)

输出：

#0 object(B) (3)    y => int(13423)     ob => object(A) (2)        a => int(223)         b => int(454)     g => str(7) "sdsdsds"---------------------B{y=>13423, ob=>A{a=>223, b=>454}, g=>"sdsdsds"}
