默认情况下,split()根据空格进行拆分,但同样也可以将其他字符序列传递给split()进行拆分。s ='these,words,are,separated,by,comma' print('\',\' separated split -> {}'.format(s.split(','))) //['these', 'words', 'are', 'separated', 'by', 'comma'] s ='abacbdebfgbhhgbabddba' print...
Lastly, an important application of strings is thesplitmethod, which returns a list of all the words in the initial string and it automatically splits by any white space. It can optionally take a parameter and split the strings by another character, like a comma or a dot 4. Formatting str...

说明:字符串对象的split()只能处理简单的情况,而且不支持多个分隔符,对分隔符周围可能存在的空格也无能为力。 #example.py# #Example of splitting a string on multiple delimiters using a regeximportre#导入正则表达式模块line='asdf fjdk; afed, fjek,asdf, foo'#(a) Splitting on space, comma, and se...
split()函数更为复杂,可以把array分为几个不对称的部分。此外,出来传入array作为parameter外,还得指定被切分部分的index。如果指定axis=1选项,索引为列索引;如果axis=0,索引为行索引。 例:要把矩阵切分为三部分,第一部分为第一列,第二部分为第二列、第三列,第三部分为最后一列。user需要想下面这样指定index ...

We can usejoin()function to split a string with specified delimiter too. names='Python'delimiter=','single_str=delimiter.join(names)print('String: {0}'.format(single_str)) Copy This shows that when String is passed as an argument to join() function, it splits it by character and with...
Semicolon:=False, Comma:=False,Space:=False, Other:=False, FieldInfo _ :=Array(1,1), TrailingMinusNumbers:=True 我们故技重施,可以查到xlDelimited、xlDoubleQuote 这些常量的值,但是这个Array(1, 1) 怎么转化为python语法,小爬目前还没找到合适的方法,有知道的童鞋,可以留言区告诉我,谢谢~ ...
