1.一一對應：

>>> data = [ ‘ACME‘, 50, 91.1, (2012, 12, 21) ]
>>> name, shares, price, date = data
>>> name
‘ACME‘
>>> date
(2012, 12, 21)
>>> name, shares, price, (year, mon, day) = data
>>> name
‘ACME‘
>>> year
2012
>>> mon
12
>>> day
 
21
>>>

>>> data = [ ‘ACME‘, 50, 91.1, (2012, 12, 21) ]
>>> name, shares, price, date = data
>>> name
‘ACME‘
>>> date
(2012, 12, 21)
>>> name, shares, price, (year, mon, day) = data
>>> name
‘ACME‘
>>> year
2012
>>> mon
12
>>> day
 
21
>>>

2.可叠代對象元素個數超過變量個數：，*匹配返回的是個列表

>>> record = (‘ACME‘, 50, 123.45, (12, 18, 2012))
>>> name, *_, (*_, year) = record
>>> name
‘ACME‘
>>> year
2012
>>>
