三个你应该注意的错误
你只需要使用groupby函数： promotion.groupby("promotion_code").agg( total_promo_sales = ("sales_qty", promotion_sales = promotion.groupby("promotion_code").agg( total_promo_sales = ("sales_qty", "sum ") ) promotion_sales.total_promo_sales.sum() # output 394 promotion.sales_qty.sum() # output 466 这个差异的原因是缺少促销代码值 promotion.groupby("promotion_code", dropna=False).agg( total_promo_sales = ("sales_qty", "sum 这是如何使用iloc方法来执行的： promotion.iloc[:4, :] # output promotion_code sales_qty price 0 A2
