数据分析-小记

fig, axis = plt.subplots(1, 2, figsize=(12,4)) axis[0].set_title("Has Partner") axis[1].set_title("Has Dependents") axis_y = "percentage of customers" gp_partner = (data.groupby('Partner')["Churn"].value_counts()/len(data)).to_frame() gp_partner.rename(columns={"Churn": axis_y}, inplace=True) gp_partner.reset_index(inplace=True)

pandas取数按照比率进行绘图时的惯用方式

(data.groupby('Partner')["Churn"].value_counts()/len(data)).to_frame()
