"Python Cookbook" "String and Text" 16. Reformat text with a fixed number of columns

Problem: Reformat some very long strings to display in the specified number of columns

Solution: The Fill () method of the TextWrap module is used to implement

#A Long Strings ="Look to my eyes, look to my eyes, the eyes, the eyes, the eyes, not around the eyes, don ' t look around the eyes, l Ook into my eyes, you ' re under."ImportTextWrapPrint(Textwrap.fill (S, 70))Print()Print(Textwrap.fill (S, 40))Print()Print(s, Textwrap.fill, initial_indent='    ')) #Initial_indent: Adds the specified character display at the beginning of the first line. The default is blank. If the first row is a blank line, it is not added.Print()Print(s, Textwrap.fill, subsequent_indent='    ')) #Subsequent_indent: In addition to the first line, all other rows add the output of this string at the beginning of the row. The default is empty.

Print ()

For the size of the terminal, it can be obtained by os.get_terminal_size ():

Import os>>> os.get_terminal_size (). Columns

The Fill () method also has additional options to control tabs, periods, and so on, see TextWrap. Document Https://docs.python.org/3.3/library/textwrap.html#textwrap.TextWrapper for the Textwrapper class
