如果在 python 中获取对象的内存地址和字典地址

def id(*args, **kwargs): # real signature unknown
    """
    Return the identity of an object.
    
    This is guaranteed to be unique among simultaneously existing objects.
    (CPython uses the object's memory address.)def id(*args, **kwargs): # real signature unknown
    """
    Return the identity of an object.

d1={'a':1,'b':2}
d2=d1
# 定义一个新字典 内容和d1一致
d3=d1.copy()

print('原始的字典d1的内存地址是  {}'.format(id(d1)))
print('通过等号赋值d2的内存地址是{}'.format(id(d2)))
print('通过copy方法d3的内存地址是{}'.format(id(d3)))
