{"library":"Sklearn","prompt":"Problem:\n\nI would like to apply minmax scaler to column A2 and A3 in dataframe myData and add columns new_A2 and new_A3 for each month.\n\nmyData = pd.DataFrame({\n    'Month': [3, 3, 3, 3, 3, 3, 8, 8, 8, 8, 8, 8, 8],\n    'A1': [1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2],\n    'A2': [31, 13, 13, 13, 33, 33, 81, 38, 18, 38, 18, 18, 118],\n    'A3': [81, 38, 18, 38, 18, 18, 118, 31, 13, 13, 13, 33, 33],\n    'A4': [1, 1, 1, 1, 1, 1, 8, 8, 8, 8, 8, 8, 8],\n})\nBelow code is what I tried but got en error.\n\nfrom sklearn.preprocessing import MinMaxScaler\n\nscaler = MinMaxScaler()\n\ncols = myData.columns[2:4]\nmyData['new_' + cols] = myData.groupby('Month')[cols].scaler.fit_transform(myData[cols])\nHow can I do this?
