Notes:df1的每一列分别乘以df2的某一列，得一列一列如：df1.loc[:,0]*df2.loc[:,1 ]

            # df1 *df2.loc[:,1 ]，会导致df1每一列的全部值，乘以df2某一列里按顺序的单一数字for temp_port in col_list_port: # 股票成本df_port_stock_cost.loc[:, temp_port] = df_ashare_adjclose.loc[:, temp_date ]# 组合权重乘以账户总资产，理论市值！df_port_stockvalue.loc[:, temp_port] = df_ashare_ana.loc[:, temp_port] * df_port_all.loc[:, temp_date ] *para_max_stock_pct  # 股票数量,向下取整数df_port_stock_num.loc[:, temp_port] = df_port_stockvalue.loc[:, temp_port] / df_port_stock_cost.loc[:, temp_port] df_port_stock_num.loc[:, temp_port] = df_port_stock_num.loc[:, temp_port].astype(int )# 组合权重乘以账户总资产，实际市值df_port_stockvalue.loc[:, temp_port] = df_ashare_ana.loc[:, temp_port] * df_port_all.loc[:, temp_date ]
