Python的深拷贝和浅拷贝

class Cpu:
    pass
class Disk:
    pass
class Computer:
    def __init__(self,cpu,disk):
        self.cpu=cpu
        self.disk=disk
#变量赋值
cpu1=Cpu()
cpu2=cpu1
print(cpu1)
print(cpu2)
#类的浅拷贝
disk=Disk()
computer=Computer(cpu1,disk)
import copy
computer2=copy.copy(computer)
print(computer,computer.cpu,computer.disk)
print(computer2,computer2.cpu,computer2.disk)
#深拷贝
computer3=copy.deepcopy(computer)
print(computer,computer.cpu,computer.disk)
print(computer3,computer3.cpu,computer3.disk)

可以通过运行结果看到其拷贝之间的区别
