Python中join和split用法实例

>>>li = ['my','name','is','bob']
>>>' '.join(li)
'my name is bob'
>>>s = '_'.join(li)
>>>s
'my_name_is_bob'
>>>s.split('_')
['my', 'name', 'is', 'bob']
其join和split的英文版解释如下：
join(...)
S.join(sequence) -> string
Return a string which is the concatenation of the strings in the
sequence. The separator between elements is S.
split(...)
S.split([sep [,maxsplit]]) -> list of strings
Return a list of the words in the string S, using sep as the
delimiter string. If maxsplit is given, at mos本文来源gao@!dai!ma.com搞$$代^@码5网@t maxsplit
splits are done. If sep is not specified or is None, any
whitespace string is a separator and empty strings are removed
from the result.
