28-python基础-python3-列表多重赋值

1-列表多重赋值常规方法

>>> cat = ['fat', 'black', 'loud']
>>> size = cat[0]
>>> color = cat[1]
>>> disposition = cat[2]

 

2-列表多重赋值技巧

>>> cat = ['fat', 'black', 'loud']
>>> size, color, disposition = cat

 

3-注意：变量的数目和列表的长度必须严格相等，否则 Python 将给出 ValueError

>>> cat = ['fat', 'black', 'loud']
>>> size, color, disposition, name = cat

Traceback (most recent call last):
File "<pyshell#84>", line 1, in <module>
size, color, disposition, name = cat
ValueError: need more than 3 values to unpack
