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

问题描述

我有一本字典:

import math
import random

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))]
}

我想把它打印出来，让它与标题很好地对齐.我可以将标题添加到字典中并始终确保它们排在最前面吗?我已经看到了几种垂直执行的方法，但我希望它的最大列宽接近最大 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:

密钥____________________标签______________________编号
1____________香料___________42
2______________________其他内容_____________16
等

Key___________________Label______________________Number
1______________________Spices_____________________42
2______________________Other Stuff_____________16
etc

显然我什至无法在此编辑器中手动执行此操作，但我希望这个想法能够实现.我也真的不想要__.只是一个占位符.
谢谢大家.

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 python2 中的字符串格式:

    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)

或者，python3 中的字符串格式:

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