使用Python将数组的元素导出到变量中(unpacking)

p = (1, 2)
x, y = p
# x = 1
# y = 2
data = ['google', 100.1, (2016, 5, 31)]
name, price, date = data
# name = 'google'
# price = 100.1
# date = (2016, 5, 31)
name, price, (year, month, day) = data
# name = 'google'
# price = 100.1
# year = 2016
# month = 5
# day = 31

p = (1, 2)
x, y, z = p

Traceback (most recent call last):
 File "<pyshell#12>", line 1, in <module>
  x, y, z = p
ValueError: not enough values to unpack (expected 3, got 2)

s = 'Hello'
a,b,c,d,e = s
# a = 'H'
# b = 'e'

data = ['google', 100.1, (2016, 5, 31)]
name, _, (_,month,_) = data
# name = 'google'
# month = '5'
# other fileds will be discarded
