python - Forward slash in json file from pandas dataframe -

i'm complete newbie json, appreciated. i'm trying convert dataframe json file.

import pandas pd  df = pd.dataframe({ 'a' : [1., 2.5],                     'b' : ['img/blue.png', 'img/red.png']}) print df 

output is

                b 0  1.0  img/blue.png 1  2.5   img/red.png 

i make json file looks this:

'[1.0,"img/blue.png"],[2.5,"img/red.png"]' 

however, when use following

out = df.to_json(orient='values')[1:-1] print out 

i instead

'[1.0,"img\\/blue.png"],[2.5,"img\\/red.png"]' 

how can forward slash print correctly in json file?

i'm not believe want those. think forward slash break json , needs escaped. have verified added slashes issue?
