string 对象的 split() 方法只适应于非常简单的字符串分割情形,它并不允许有多个分隔符或者是分隔符周围不确定的空格。当你需要更加灵活的切割字符串的时候,最好使用re.split()方法: >>> line = 'asdf fjdk; afed, fjek,asdf, foo' >>> import re >>> re.split(r'...
Use string slicing to remove the first and last characters from a string, e.g. `result = my_str[1:-1]`.

Check if the next character (if not already at the end of the string) is ‘-’ or ‘+’. Read this character in if it is either. This determines if the final result is negative or positive respectively. Assume the result is positive if neither is present. ...

Coming very late to the party I want to add my solution to trim text at character level that also handles whitespaces properly. def trim_string(s: str, limit: int, ellipsis='…') -> str: s = s.strip() if len(s) > limit: return s[:limit-1].strip() + ellipsis return s Sim...
