(1)按照空格分割出单词 (i)使用 split 切分 In [3]: letter ='a b c'In [4]: letter.split('') Out[4]: ['a','b','','','c'] (ii)使用 re.split 切分 In [5]:importre In [7]: re.split(r'\s+', letter) Out[7]: ['a','b','c'] 可以看出,使用re.split切分效果更佳更...
我只需要在字符“d”处放置一个maxsplit参数,我怎么做? 请执行以下操作: normal_string = "1d30 drake dreke" # first split by d start, end = normal_string.split("d", maxsplit=1) # the split by space and concat the results res = start.split() + end.split() print(res) Output ['1'...
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...
str.split(s[, num]) # 以s为分隔符切片str num=string.count(str)) 以 str 为分隔符截取字符串,如果 num 有指定值,则仅截取 num+1 个子字符串 str.splitlines([keepends]) # 按照行分隔,返回一个包含各行作为元素的列表.按照行('\r', '\r\n', \n')分隔,返回一个包含各行作为元素的列表,如果...
