小道具：テーブル生成用書式出力

一覧の可読性を向上させるための小道具。

Python

    space = ' ' * space
    fmtdata = [datafmt % d for d in data]
    msgfmt = msgfmt.replace('#', str(max(len(s) for s in fmtdata)))
    msglist = [(msgfmt % d) + separator for d in fmtdata]
    return ''.join((prefix + space.join(msglist[i:i+width]) + suffix)
                   for i in range(0, len(msglist), width))

Python

print(format_list(range(44)))
print(format_list(range(44), msgfmt='%-#s', space=2, prefix=(' ' * 4)))
print(format_list(range(44), datafmt='%#04x', width=8))
