在pandas中水平和垂直组合多个pivot表

Question

I have a dataset that looks like this:

raw data

and I need to get this output: desired output

Is using pivot tables (in python pandas) first for each Q, then appending over each column, and then merging the resulting dataframes for reach Q the best way to do it? Any suggestion on how to do that to get the right format?

Answer 1

Try this:

df1 = pd.melt(df, id_vars=["gender",'region'], value_vars=['q1','q2'], value_name='ques')
df2 = pd.melt(df1, id_vars='ques', value_vars=["gender",'region'], value_name='col')
df3 = pd.pivot_table(df2,index='ques',columns=['col'], aggfunc='count').fillna(0)
print(df3)
