Textwrap-Python中的文本环绕和填充
textwrap模块提供执行包装或填充的TextWrapper类。具有相同目的的便利功能。

填写（文字）
将单个段落包装为文本，并返回包含被包装段落的单个字符串。
>>> sample_text = ''' The textwrap module provides some convenience functions, as well as TextWrapper class that does all the work. If you’re just wrapping or filling one or two text strings, the convenience functions should be good enough; otherwise, you should use an instance of TextWrapper for efficiency. ''' >>> import textwrap >>> for line in (textwrap.wrap(sample_text, width = 50)): print (line) The textwrap module provides some convenience functions, as well as TextWrapper class that does all the work. If you’re just wrapping or filling one or two text strings, the convenience functions should be good enough; otherwise, you should use an instance of TextWrapper for efficiency.
