python - python 中嵌套循环的 pretty-print 输出

Question

我有一个像这样的嵌套循环:

for a in b.keys():
    for c in b[a]:
        out = '%-30s %s' % (c, a)
        space = out.count(' ')
        split = space * '-'
        print '\t%-30s %s  %-10s' % (c, split, a)

所以结果是:

test1         ------- something1
test23sdfsf   ----- dsffdgdgfddfsdf

但我想要的是:

test1 -------------- something1
test23sdfsf -------- dsffdgdgfddfsdf

Answer 1

如果您想使用 30 的 maxwidth，请执行以下操作:

for a in b.keys():
    for c in b[a]:
        print("%s %s" % (c.ljust(30, '-'), a))
