Question

我构建了一个类来处理许多带有常见输入的不同函数。但是，我刚遇到需要更改通过self传递的变量之一的情况。我该怎么做呢？这是一个例子：

class Test: 
    def __init__(self, test_variable):
        self.test_var = test_variable

    @property
    def some_function(self): 
        if self.test_var < 0:
           self.test_var = 'New Output'   #this is the line that I can't get 
                                          #get to work and I was hoping to update it here
                                          #so I could use it in later functions
        return self.test_var

谢谢！

您应该删除@property属性。然后，您可以通过执行x.test_var = 5来设置它。如，

class Test: 
    def __init__(self, test_variable):
        self.test_var = test_variable

    def some_function(self): 
        if self.test_var < 0:
           self.test_var = 'New Output'   #this is the line that I can't get 
                                          #get to work and I was hoping to update it here
                                          #so I could use it in later functions
        return self.test_var

x = Test(-1)

print(x.some_function())
x.test_var = 5
print(x.some_function())

返回

New Output
5

类变量更新
