1 遍历字典的key

#1 遍历字典的key
info = {"name":"Tom","sex":"male","age":27}
for k in info.keys():
    print(k)

#2 遍历字典的value
info = {"name":"Tom","sex":"male","age":27}
for k in info.keys():
    print(info[k])

#2 遍历字典的value
info = {"name":"Tom","sex":"male","age":27}
for v in info.values():
    print(v)

#3 遍历字典的元素   type(items)  是元组形式的  <class 'tuple'>
info = {"name":"Tom","sex":"male","age":27}
for items in info.items():
    print(items)

#4 遍历字典的键值对
info = {"name":"Tom","sex":"male","age":27}
for key,value in info.items() :
    print(f'{key} = {value}')
