I got a large dataframe like that, which basically looks like this:

which I would like to turn into a dictionary like:

{24.6: ["test",43,555],
63.9: ["test",31,666]}

What I found so far was https://stackoverflow.com/a/67496211/9218349, which would result in:

dict(zip(zip(df.km),zip(df.Name, df.Min,df.Max)))

this way i receive a dictionary of tuples, but I wont the keys to be floats and the values to be strings and floats. The floats should generally have 2 decimal places.

How would I do that?

CodePudding user response：

Use to_dict('list') on the transposed DataFrame:

df.set_index('km').T.to_dict('list')

output:

{24.6: ['test', 43, 555], 63.9: ['test', 31, 666]}

NB. note that in case you have duplicated values in "km", as you can only have unique keys in a dictionary, only the latest row will be kept
