当然,如果您有多个分隔符,则使用 re.split() 会获得更好的性能,但这是解决问题的一种非常聪明且易于理解的方法。 (2认同) Kos*_*Kos 98 对于任何可迭代的分隔符,使用正则表达式,这是一种安全的方法: >>> import re >>> delimiters = "a", "...", "(c)" >>> example = "stackoverflow (c) ...
Up to now we have providedspaceas separator in elements in new string. But we can specify different delimiters by changingspacewith new delimiter like,command. 到目前为止,我们已经在新字符串的元素中提供了space作为分隔符。 但是,我们可以通过改变指定不同的分隔符space与像新的分隔符,命令。
其结果等同于先调用 split(),然后将结果列表中各个单词的首字母大写,然后调用 join() 合并结果。 maketrans() 函数将创建转换表,可以用来结合 translate() 方法将一组字符修改为另一组字符,这种做法比反复调用 replace() 更为高效。 import string leet = string.maketrans('abegiloprstz', '463611092572') ...
If sep is given, consecutive delimiters are not grouped together and are deemed to delimit empty strings (for example, '1,,2'.split(',') returns ['1', '', '2']). Splitting an empty string with a specified separator returns ['']. Noticing how the leading and trailing whitespaces ...
