Function 如何添加一个参数的多个实例，使其成为代码中的某个变量，并将该参数作为函数中的一个参数使用

嘿，伙计们，在函数中传递了进程、移位和学习曲线级参数之后，我的代码给出了速率。有7个班次，现在我想做的是，我想做从A到E的白班，从F到G的夜班，总共9个班次，但我不知道怎么做。任何建议都会很有帮助

    import csv

    def Calc(process, shift, lc):
        f = open('C:\\Users\\keshabg\\Desktop\\sql_testing\\table_1.csv')
        csv_f = csv.reader(f)
        res_units = []
        res_hours = []
        sum_units = 0
        sum_hours = 0
        for row in csv_f:
            if row[2] == shift and row[3] == process and row[4] == lc:
                res_units.append(row[5])
                res_hours.append(row[6])
       for num in res_units:
           sum_units = float(sum_units) + float(num)
       for num in res_hours:
           sum_hours = float(sum_hours) + float(num)
       try:
           res_rate = round(sum_units/sum_hours, 2)
       except ZeroDivisionError:
           res_rate = "N/A"

       return "The Units Processed was: ", res_units , "The Hours worked was: " , res_hours , "The total units was: " , sum_units , "The total hours was: " , sum_hours , "The rate: " , res_rate
