Question

我创建了一个基本菜单类，如下所示：

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

我想要做的是格式化标题和正文，使它们几乎适合预制盒子。无论我作为身体传递什么，显示器都能够适合它。格式看起来像这样。

********************************************************************************
*    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         *
*                                                                              *

我认为这个标题很容易，但我迷失在身体上。

Answer 1

#!/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"
);
