无法在django

Question

我有一个观点，我正在尝试执行一个简单的数学计算，我收到的错误让我失望。

所以我有一个方法可以接受两个变量，一个十进制值和一个整数。我想取数字并将小数除以整数。我收到以下错误，我不知道为什么......

这是方法

def SplitEven(record, amount):
    record_count = record.count
    print(record_count)
    print(amount)
    split_amount = amount/record_count
    print(split_amount)
    rounded_amount = round(split_amount, 2)
    print (record_count)
    print (amount)
    print (split_amount)
    return rounded_amount

这是错误消息：

unsupported operand type(s) for /: 'str' and 'int'

C:\Users\OmarJandali\Desktop\opentab\opentab\tab\views.py in addTransaction
                                taxSplit = SplitEven(record, amount) 

C:\Users\OmarJandali\Desktop\opentab\opentab\tab\views.py in SplitEven
                split_amount = amount/record_count

Answer 1

from decimal import Decimal

def SplitEven(record, amount):
    record_count = Decimal(record.count)
    split_amount = Decimal(amount)/record_count
    rounded_amount = round(split_amount, 2)
    return rounded_amount
