for循环: 遍历字典, 分别打印key, value, key:value

#遍历字典, 分别打印key, value, key:value
emp =  { 'name' : 'Tom' , 'age' : 20 ,  'salary'  : 8800.00 }

for  k in  emp.keys():
                print ( 'key = {}' . format (k))

for  v in  emp.values():
                print ( 'values = {}' . format (v))

for  v,k in  emp.items():
                print ( '{v}:{k}' . format (v =  v, k =  k))

 打印结果:
key = name
key = age
key = salary

values = Tom
values = 20
values = 8800.0

name:Tom
age:20
salary:8800.0
