如何以表格形式打印多个对象的参数？

Question

我有一个对象列表，我想在一个漂亮的表中打印每个对象的参数。

我的代码在这里：

class item(object):
    def __init__(self, thing, owner, color):
        self.thing = thing
        self.owner = owner
        self.color = color

bin = []
bin.append(item('shirt', 'John', 'red'))
bin.append(item('skirt', 'Jane', 'blue'))

## Need help here
## Can't figure this out

print '%-10s %-10s %-10s' % (bin[0].thing, bin[0].owner, bin[0].color)

我想要得到的输出是

shirt       skirt
John        Jane
red         blue

Answer 1

for attr in (‘thing’, ‘owner’, ‘color’):
for item in bin:
print ‘%-10s’%getattr(item, attr),
print

使用列表理解更紧凑

for atts in ('thing', 'owner', 'color'):
    print ' '.join('%-10s'%getattr(item, attr) for item in bin)
