Mewɔ pandas dataframe a mewɔ kɔlumn "x", "y", ne "z". Mepɛ sɛ mekɔ so frɛ ɔha bi wɔ kɔlumn "x" mu na mepɛ sɛ mekɔsoɛ ɔha biara a ɛde "a" wɔ kɔlumn "y" mu wɔ ɔha biara mu. Mepɛ sɛ mekɔsoɛ ɔha biara a ɛde "a" wɔ kɔlumn "y" mu.<|eot_id|><|start_header_id|>assistant<|end_header_id|>

wobetumi de `groupby` method wɔ Pandas mu ahwɛ "x" column na wobetumi de `mean` method ahwɛ "y" column mu nnɔnhwerew biara. Sɛ wopɛ sɛ woyɛ "a" nnɔnhwerew a ɛfiri "z" a ɛfiri "b" no, wobetumi de boolean mask ahwɛ "z" a ɛfiri "b" no, na wobetumi de `sum` method ahwɛ "a" nnɔnhwerew no. Ɛfiria, fa nnɔnhwerew no bi wɔ ɔha biara mu na woahwɛ nnɔnhwerew a ɛfiri "a" mu. Ɛyɛ ho nhwɛso:  ``` df = pd.DataFrame({     "x": [1, 1, 2, 2, 3, 3],     "y": ["a", "b", "a", "a", "b", "a"],     "z": ["c", "d", "c", "e", "f", "g"] })  mask = (df["y"] == "a") & (df[<|eot_id|>
