将字典转换为 pandas df，其中值是数字列表，同时保持列表格式

Question

Have a dictionary that looks something like this:

opt = {
            red: [28, 30, 32],
            blue: [30],
            green: [28, 32, 34, 38]
        }

And I'm looking to convert it to a pandas dataframe that looks like this:

| size     | color                        |
| -------- | --------------               |
| sml      | [red, blue, green]           |
| med      | [red]                        |
| lrg      | [red, blue, green, orange]   |

Any way to do that easily?

Answer 1

df = pd.DataFrame( { 'color':[x for x in opt], 'rgb':[ opt[x] for x in opt] } )
