在Python Shell中将文本格式化为框

Question

我创建了一个基本的菜单类，长得像这样：

class Menu:
    def __init__(self, title, body):
        self.title = title
        self.body = body
    def display(self):
        #print the menu to the screen

我想做的是把标题和内容格式化一下，让它们能适应预先设计好的框框。也就是说，不管我传入什么内容，显示出来的样子都能放得下。格式大概是这样的：

********************************************************************************
*    Here's the title                                                          *
********************************************************************************
*                                                                              *
*  The body will go in here.  Say I put a line break here ---> \n              *
*  it will go to the next line.  I also want to keep track\n                   *
*  \t   <----- of tabs so I can space things out on lines if i have to         *
*                                                                              *
********************************************************************************

我觉得标题部分应该比较简单，但我在内容部分有点迷糊。

Answer 1

你也可以试试标准的 'textwrap' 模块。

Answer 2

#!/usr/bin/env python

def format_box(title, body, width=80):
    box_line = lambda text: "*  " + text + (" " * (width - 6 - len(text))) + "  *"

    print "*" * width
    print box_line(title)
    print "*" * width
    print box_line("")

    for line in body.split("\n"):
        print box_line(line.expandtabs())

    print box_line("")
    print "*" * width

format_box(
    "Here's the title",

    "The body will go in here.  Say I put a line break here ---> \n"
    "it will go to the next line.  I also want to keep track\n"
    "\t<----- of tabs so I can space things out on lines if i have to"
);

当然可以！不过你没有提供具体的内容，我无法进行翻译。如果你能把需要翻译的内容发给我，我会很乐意帮你把它变得更简单易懂。
