Question

在下面的示例中，我将需要执行此功能约7次。例如，唯一的变化将是strength，而不是perception。在您看到strength一词的任何地方，都需要对其进行更改，包括在Qt函数中，例如self.strengthSpin.setValue()。

有没有一种方法可以完成多次复制/粘贴代码？

if stat == "strength":
    newValue = self.strengthSpin.value()
    varChange = newValue - strength
    if varChange > 0:
        if statPoints - varChange >= 0:
            statPoints -= varChange
            self.statPointsLCD.setProperty("intValue", statPoints)
            strength += varChange
            self.strengthSpin.setValue(strength)
        else:
            print("not enough stat points")
            self.strengthSpin.setValue(strength)
    else:
        if newValue > 0:
            print("should be adding")
            statPoints -= varChange
            self.statPointsLCD.setProperty("intValue", statPoints)
            strength += varChange
            self.strengthSpin.setValue(strength)
        else:
            print("must be at least 0")
            self.strengthSpin.setValue(strength)

是的，但是您必须将strength和statPoints保存为'self'的属性（或将它们传递给方法，然后再从中返回它们）：

def update_value(self, name):  # name is 'strength'
    spin = getattr(self, name + 'Spin')
    newValue = spin.value()
    oldValue = getattr(self, name)
    varChange = newValue - oldValue
    if varChange > 0:
        if self.statPoints - varChange >= 0:
            self.statPoints -= varChange  # if this variable should be different for different names, use setattr instead
            self.statPointsLCD.setProperty("intValue", statPoints)
            setattr(self, name, newValue)
            spin.setValue(newValue)
        else:
            print("not enough stat points")
            spin.setValue(oldValue)
    else:
        if newValue > 0:
            print("should be adding")
            self.statPoints -= varChange
            self.statPointsLCD.setProperty("intValue", statPoints)
            setattr(self, name, newValue)
            spin.setValue(newValue)
        else:
            print("must be at least 0")
            spin.setValue(oldValue)

调用def并根据传递的值更改Qt和变量
