python字典key、value和item

python字典key、value和item:

>>> dict1 = {'name': 'TOM', 'age': 20, 'gender': '男'}
>>> for key in dict1.keys():
	print(key)

	
name
age
gender
>>> for value in dict1.values():
	print(value)

	
TOM
20
男
>>> for item in dict1.items():
	print(item)

	
('name', 'TOM')
('age', 20)
('gender', '男')

dict1 = {‘name’: ‘TOM’, ‘age’: 20, ‘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)
# 目标： key=value
print(f’{key}={value}’)
