day4-解包

#解包，数组，元祖，字符串都可以，只要有下标
msg = 'admin,123'
username1=msg.split(',')[0]
pwd1=msg.split(',')[1]
# 可以合并成一行代码
username,pwd=msg.split(',')

l=[1,2,3]
f,k,g=l

l2=(1,2,3)
f1,k1,g1=l2

l3='123'
f2,k2,g2=l3

print(f2,g2,k2)

d={"username":"admin","password":'123'}
print(d.items())
for k,v in d.items():
    print(k,v)
