Python - 将字典打印为具有标题的水平表 [英] Python - Printing a dictionary as a horizontal table with headers

问题描述

我有一个字典：

d = {1: ["Spices", math.floor(random.gauss(40, 5))],
    2: ["Other stuff", math.floor(random.gauss(20, 5))],
    3: ["Tea", math.floor(random.gauss(50, 5))],
    10: ["Contraband", math.floor(random.gauss(1000, 5))],
    5: ["Fruit", math.floor(random.gauss(10, 5))],
    6: ["Textiles", math.floor(random.gauss(40, 5))]
}

我想打印出来，所以它很好地与标题排列。我可以将标题添加到字典中，并始终确保它们出现在顶部？
我已经看到了一些垂直的方法，但是我想让它出现最大列宽接近最大str（）或int（）。

I want to print it out so it lines up nicely with headers. Can I add the headers to the dictionary and always be sure they come out on top? I've seen a few ways to do it vertically but I'd like to have it come out with max column widths close to the max str() or int().

示例：

Key_ _ __ _ __ _ 标签的 _ __ _ __ _ ___ 号码

1 _ __ _ __ _ ___ em>香料 _ __ _ __ _ __ 42

2 _ __ _ __ _ ___ 其他东西 _ ____ _16

etc

Key________Label__________Number
1__________Spices_________42
2__________Other Stuff______16
etc

显然我甚至不能在这个编辑器手动，但我希望这个想法遇到。
我也不是真的想要__。只是一个占位符。

感谢所有。

Apparently I can't even do this inside of this editor manually, but I hope the idea comes across. I also don't really want the __ either. Just a place holder.
Thanks all.

推荐答案

您可以使用字符串格式：

print "{:<8} {:<15} {:<10}".format('Key','Label','Number')
for k, v in d.iteritems():
    label, num = v
    print "{:<8} {:<15} {:<10}".format(k, label, num)

输出：

Key      Label           Number    
1        Spices          38.0      
2        Other stuff     24.0      
3        Tea             44.0      
5        Fruit           5.0       
6        Textiles        37.0      
10       Contraband      1000.0
