字典的循环遍历

1、遍历字典的key

dict1 = {'name': 'kk', 'age': 25, 'gender': '男'}
for a in dict1.keys():
    print(a)

2、遍历字典的value

dict1 = {'name': 'kk', 'age': 25, 'gender': '男'}

for value in dict1.values():
    print(value)

3、遍历字典的元素

dict1 = {'name': 'kk', 'age': 25, 'gender': '男'}

for item in dict1.items():
    print(item)

4、遍历字典的键值对

dict1 = {'name': 'kk', 'age': 25, 'gender': '男'}

# xx.items():返回可迭代对象，内部是元组，元组有2个数据
# 元组数据1是字典的key，元组数据2是字典的value
for key,value in dict1.items():
    print(key)
    print(value)
    print(f'{key}={value}')
