行的python pandas着色

Question

我有这段代码，每个时间段的颜色都不同，所以更容易导航。问题是，有时并不是所有的插槽都会被填充，然后我在下一个插槽上得到相同的颜色，并且很难区分哪个插槽是哪个插槽。 我怎样才能让这段代码更优雅，让python决定何时有下一个插槽来改变颜色。我想将这些颜色更改为“二进制”。

    color = '#F5EEF8'
    if row.values[0] == '06:40':
        color = '#EBF5FB  '
    elif row.values[0] == '07:10':
        color = '#FEF9E7  '
    elif row.values[0] == '07:40':
        color = '#EBF5FB  '

下面的方法怎么样：

In [112]: colors=['#EBF5FB  ','#FEF9E7  ']

In [113]: df
Out[113]:
    Time title     x
0  06:40     a  2011
1  06:40     b  2010
2  07:10     c  2000
3  08:10     d  1983

In [114]: df.assign(col=np.take(colors, df.groupby('Time').ngroup() % 2))
Out[114]:
    Time title     x        col
0  06:40     a  2011  #EBF5FB
1  06:40     b  2010  #EBF5FB
2  07:10     c  2000  #FEF9E7
3  08:10     d  1983  #EBF5FB
