python中的whitespace python中strip()和split()在无参数的情况下使用whitespace做为默认参数,在帮助文档中对whitespace的解释为6个字符,它们是space, tab, linefeed, return, formfeed, and vertical tab wiki的ASCII中对whitespace的定义多了一个backspace,它们是...
For example, declare a string and perform re.split() to split them into an array of substrings. To take trailing and leading whitespaces into consideration, then add a + sign to the RegEx string to match one or more consecutive whitespaces as a single group. Also, append the keyword r...

猜测 There should be one-- and preferably only one --obvious way to do it. # 而是尽量找一种,最好是唯一一种明显的解决方案(如果不确定,就用穷举法) Although that way may not be obvious at first unless you're Dutch. # 虽然这并不容易,因为你不是 Python 之父(这里的Dutch是指Guido) Now is...
split() # Splits on one or more whitespace characters. <list> = <str>.split(sep=None, maxsplit=-1) # Splits on 'sep' str at most 'maxsplit' times. <list> = <str>.splitlines(keepends=False) # On [\n\r\f\v\x1c-\x1e\x85\u2028\u2029] and \r\n. <str> = <str>.join...

抱歉,field_names不像一个str那样嘎嘎叫:它没有.replace,或者返回我们无法.split的东西。④如果引发了AttributeError,那么field_names不是一个str,我们假设它已经是一个名称的可迭代对象。⑤为了确保它是可迭代的并保留我们自己的副本,将我们拥有的内容创建为一个元组。tuple比list更紧凑,还可以防止我的代码误改名称...
strip() # Strips all whitespace characters from both ends. <str> = <str>.strip('<chars>') # Strips all passed characters from both ends. <list> = <str>.split() # Splits on one or more whitespace characters. <list> = <str>.split(sep=None, maxsplit=-1) # Splits on 'sep' ...
Matches a whitespace.By default, decimal characters and alphanumerics from all alphabets are matched unless 'flags=re.ASCII' is used. It restricts special sequence matches to the first 128 Unicode characters and also prevents '\s' from accepting '\x1c', '\x1d', '\x1e' and '\x1f' (non...
maxsplit (optional) is the maximum number of splits that can be performed on the input string. If the separator appears more times than the value of maxsplit, then we cut the input string as many times as the value of maxsplit. After that, the rest of the string becomes one single ...
