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:
# object(B) ()
y => int()
ob => object(A) ()
a => int()
b => int()
g => str() "sdsdsds"
---------------------
B{y=>, ob=>A{a=>, b=>}, g=>"sdsdsds"}
