[Python知识库]015-Python入门（遍历字典）

#1.遍历字典的key
for key in dict1.keys():
    print(key)      # name age weight height

#2.遍历字典的value
for value in dict1.values():
    print(value)       #jch1  22  71.2  170

#3.遍历字典的元素
for item in dict1.items():
    print(item)        #('name', 'jch1') ('age', 22)  ('weight', 71.2) ('height', 170)

#4.遍历字典的键值对
for key, value in dict1.items():
    print(f'{key} = {value}')   #name = jch1 age = 22 weight = 71.2 height = 170
