のPython - リストのグループ行パンダのデータフレーム内

Question

私はこのようなデータフレーム持っている：私はさまざまな方法を試してみましたが、それでもこれをうまくできなかった

long lat  Place 
-6.779  61.9  Aarhus 
-6.790  62.0  Aarhus  
54.377  24.4  Dhabi 
38.834  9.0  Addis 
35.698  9.2  Addis

Is it possible to transform the dataframe into a format like below? 

Office long + lat 
Aarhus  [[-6.779,61.9], [-6.790,62.0]] 
Dhabi  [[54.377]] 
Addis  [[38.834,9.0], [35.698,9.2]] 

を。

df2["index"] = df2.index 
df2["long"]=df2.groupby('index')['long'].apply(list) 
list 1= [] 
for values in ofce_list: 
    if df['Office'].any() == values: 
     list1.append(df.loc[df['Office'] == values, 'long']) 

    But this returned a series in a list instead which is not desired. Please help. Thank you so much. 

Answer 1

df.groupby('Place')[['long','lat']].apply(lambda x :x.values.tolist()).\ 
     reset_index(name='long + lat') 
Out[1380]: 
    Place      long + lat 
0 Aarhus [[-6.779, 61.9], [-6.79, 62.0]] 
1 Addis [[38.834, 9.0], [35.698, 9.2]] 
2 Dhabi  [[54.376999999999995, 24.4]]
