print(s.split()) ['KDnuggets', 'is', 'a', 'fantastic', 'resource'] 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',...
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...
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...
CSV(Comma-Separated Values)是一种常见的二维数据文件格式,可以用字典类型表示,其中数据以逗号分隔。在Python中,可以使用内置的csv模块来读写CSV文件。通过csv.reader()和csv.writer()对象,可以方便地读取和写入CSV文件中的数据。例如,可以使用csv.reader()从CSV文件中读取数据到二维列表中,或使用csv.writer()将二维...

Finally, we used the split method with a space delimiter to create a list out of our string. We will use this again later in the chapter when parsing input from the network. TIP To find out more string functions to test on your own, you can visit the Python reference manual for ...

Using split() function Apart from splitting with thejoin()function,split()function can be used to split a String as well which works almost the same way as thejoin()function. Let’s look at a code snippet: names=['Java','Python','Go']delimiter=','single_str=delimiter.join(names)print...
