Python 如何计算最佳列宽？

我有一小组列数据值，我想在可变宽度显示器中显示。一个列的大小范围很小（比如8-10个字符），一个列显示UUID（总是36个字符），其他列是可变长度标识符

我想最大限度地增加我可以显示的数据量，因为终端可能会窄到72个字符，宽到大约400个字符

超过指定列宽的值将被缩写

我该怎么计算呢

我正在使用python，如果它对任何人都重要的话。

我认为您需要更具体地说明您的问题所在。为什么不在填充可用宽度之前按一定顺序分配列呢？

def getMaxLen(xs):
    ys = map(lambda row: map(len, row), xs)
    return reduce(
        lambda row, mx: map(max, zip(row,mx)),
        ys)

def formatElem((e, m)):
    return e[0:m] + " "*(m - len(e))

# reduceW is some heuristic that will try to reduce
# width of some columns to fit table on a screen.
# This one is pretty inefficient and fails on too many narrow columns.
def reduceW(ls, width):
    if len(ls) < width/3:
        totalLen = sum(ls) + len(ls) - 1
        excess = totalLen - width
        while excess > 0:
            m = max(ls)
            n = max(2*m/3, m - excess)
            ls[ls.index(m)] = n
            excess = excess - m + n
    return ls


def align(xs, width):
    mx = reduceW(getMaxLen(xs), width)
    for row in xs:
        print " ".join(map(formatElem, zip(row, mx)))

data = [["some", "data", "here"], ["try", "to", "fit"], ["it", "on", "a screen"]]
align(data, 15)
>>> some data here 
>>> try  to   fit  
>>> it   on   a scr
