python中return和yield

def wx():
    a = ‘wx‘
    b = ‘无邪‘
    return a, b
print(wx())
print(type(wx()))


-----------执行结果---------------------

(‘wx‘, ‘无邪‘)
<class ‘tuple‘>

def wx():
    a = ‘wx‘
    b = ‘无邪‘
    return (a, b)
print(wx())
print(type(wx()))

-----------执行结果-------------------
(‘wx‘, ‘无邪‘)
<class ‘tuple‘>

def wx():
    a = ‘wx‘
    b = ‘无邪‘
    return [a, b]
print(wx())
print(type(wx()))


-------------执行结果----------------
[‘wx‘, ‘无邪‘]
<class ‘list‘>

return返回一个数，是原类型，返回多个是元祖类型

def wx():
    a = ‘wx‘
    b = ‘无邪‘
    return [a, b],[a,b]
print(wx())
print(type(wx()))

-------------执行结果----------------

([‘wx‘, ‘无邪‘], [‘wx‘, ‘无邪‘])
<class ‘tuple‘>

def wx():
    a = ‘wx‘
    b = ‘无邪‘
    return {a, b}
print(wx())
print(type(wx()))

-----------执行结果---------------
{‘无邪‘, ‘wx‘}
<class ‘set‘>

return返回一个数，是原类型，返回多个是元祖类型

def wx():
    a = ‘wx‘
    b = ‘无邪‘
    return {a, b},{a,b}
print(wx())
print(type(wx()))

-----------执行结果---------------

({‘wx‘, ‘无邪‘}, {‘wx‘, ‘无邪‘})
<class ‘tuple‘>

def wx():
    a = ‘wx‘
    b = ‘无邪‘
    yield [a, b]
print(wx())
print(type(wx()))
print(next(wx()))
print(next(wx())[0])
print(next(wx())[1])

-------------执行结果-----------------------
<generator object wx at 0x0000021AC9B93BA0>
<class ‘generator‘>
[‘wx‘, ‘无邪‘]
wx
无邪
