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

使用列表更简洁

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

这是我很久以前发现的一个非常有用并且仍然有效的东西。我最近终于抽出时间更新了最新的py 2.7.x和3.x标准，尽管大多数更改都是我所说的装饰性的和/或相当琐碎的。

"""
Here is TextFormatter, a simple module for formatting text into
columns of specified widths. It does multiline wrapping and supports
LEFT, CENTER (or CENTRE), and RIGHT alignment.

Revisions:
    SKWM    Made filling & padding optional, tweaked some edge cases.
    MRM     Removed import of deprecated string module, made all classes
            explicitly new style, capitalized public constants, updated
            documentation. Tweaked test() function.
    MRM     Modified to work in both Python 2.7 and 3.x.

    Formats text into columns.

    Constructor takes a list of dictionaries that each specify the
    properties for a column. Dictionary entries can be:

       'width'     : the width within which the text will be wrapped
       'alignment' : LEFT | CENTER | RIGHT
       'margin'    : number of space characters to prefix in front of column

    The compose() method takes a list of strings and returns a formatted
    string consisting of each string wrapped within its respective column.

    Example:
        import textformatter

        formatter = textformatter.TextFormatter(
            (
                {'width': 10},
                {'width': 12, 'margin': 4},
                {'width': 20, 'margin': 8, 'alignment': textformatter.RIGHT},
            )
        )

        print(formatter.compose(
            (
                "A rather short paragraph",
                "Here is a paragraph containing a veryveryverylongwordindeed.",
                "And now for something on the right-hand side.",
            )
        ))

    gives:

        A rather      Here is a                    And now for
        short         paragraph               something on the
        paragraph     containing a            right-hand side.
