After i created a data frame and make the function get_dummies on my dataframe:
df_final=pd.get_dummies(df,columns=['type'])
I got the new columns that I want and everything is working.
My question is, how can I get the new columns names of the get dummies? my dataframe is dynamic so I can’t call is staticly, I wish to save all the new columns names on List.
>Solution :
An option would be:
df_dummy = pd.get_dummies(df, columns=target_cols)
df_dummy.columns.difference(df.columns).tolist()
where df is your original dataframe, df_dummy the output from pd.get_dummies, and target_cols your list of columns to get the dummies.
