Question

在我的程序中，它会询问你输入，输入会给你一个相应的推论，但是我的代码一直给我相同的输出，即“Rate Deduction：634.57” 即使它应该给我一个更高的扣除额“扣除费率：1624.57”或“费率扣除：2655.72”

我为生锈的英语道歉，但非常感谢你，如果你愿意帮助我的话。

Answer 2

如果您在工资4和工资5中检查过的if，则无法访问代码，因为在if if block check for salary 3之后调用again()。

仅在TaxCheck()方法结束时调用nowy_komentarz.post = detale_bajki ... return render(request, 'html page', {'key': 'what you want to return to your context'}) # don't fornget to add some return to your view.方法。

此外，您应该将工资支票的顺序从高到低更改，即从工资5到工资3。
