python 字符串 分割 查找

字符串分割： s.split([sep, [maxsplit]]) 以sep是分隔符，把s分割成一个list。sep默认为空格。maxsplit是分割的次数，默认是对整个s进行分割 s.rsplit([sep, [maxsplit]]) 和split()的区别是它是从s的串尾往前进行分割 s.splitlines([keepends]) 把s按照行分隔符分成一个list。如果keepends为True则list的每个元素保留行分割符，如果为False则不保留分隔符 >>> s 'hello World! Everyone! This Is My First String!' >>> s.split() ['hello', 'World!', 'Everyone!', 'This', 'Is', 'My', 'First', 'String!'] >>> s.split(' ',4) ['hello', 'World!', 'Everyone!', 'This', 'Is My First String!'] >>> s.split('e') ['h', 'llo World! Ev', 'ryon', '! This Is My First String!'] >>> s.rsplit() ['hello', 'World!', 'Everyone!', 'This', 'Is',
