在 Python 中使用一个函数（方法）的返回值到另一个函数（方法）中答案

我正在尝试使用从函数 - get_reg_check_type 返回的值“str(check)”并在另一个函数 - get_status_type 中使用它。我该怎么做？

#---- 获取注册检查类型 # 如果寄存器存在且已解锁，则返回“CHECK”； "CHECK_NRF" 如果寄存器不存在或被锁定

    def get_reg_check_type(self, addr, lock=definitions.LockTest.LOCK):
        check = "CHECK_NRF" # NOTE: if items (bits) are locked, check will stay set to CHECK_NRF
        for items in self.register_field_collection:
            for item in items:
                # Bit exists and is unlocked - return "CHECK"
                if (addr == item.register_address):
                    if ((lock == definitions.LockTest.LOCK) and (item.register_write_lock in [definitions.RegWriteLock.NO, definitions.RegWriteLock.FRW])) or \
                       ((lock == definitions.LockTest.A  ) and (item.register_write_lock in [definitions.RegWriteLock.NO, definitions.RegWriteLock.FRW, definitions.RegWriteLock.FRU])) or \
                       ((lock == definitions.LockTest.AB ) and (item.register_write_lock in [definitions.RegWriteLock.NO, definitions.RegWriteLock.FRW, definitions.RegWriteLock.FRU])) or \
                       ((lock == definitions.LockTest.ABC) and (item.register_write_lock in [definitions.RegWriteLock.NO, definitions.RegWriteLock.FRW, definitions.RegWriteLock.FRU, definitions.RegWriteLock.FEBU])):
                        check = "CHECK"
        return str(check)
        
    def get_status_type(self):
        if self.check = "CHECK_NRF"
            status_value = 8'h44
        else:
            status_value = 8'h40
        return status_value

【问题讨论】：

这些函数在同一个类中？
在您的 get_status_type 函数中，只需调用 get_reg_check_type 函数。 check = self.get_reg_check_type(addr)
@nagyl 是的，他们在同一个班级

【解决方案1】：

如果在同一个类中可以找到这些函数，您可以先调用get_reg_check_type，然后再调用get_status_type。

def get_reg_check_type(self, addr, lock=definitions.LockTest.LOCK):
        check = "CHECK_NRF" # NOTE: if items (bits) are locked, check will stay set to CHECK_NRF
        for items in self.register_field_collection:
            for item in items:
                # Bit exists and is unlocked - return "CHECK"
                if (addr == item.register_address):
                    if ((lock == definitions.LockTest.LOCK) and (item.register_write_lock in [definitions.RegWriteLock.NO, definitions.RegWriteLock.FRW])) or \
                       ((lock == definitions.LockTest.A  ) and (item.register_write_lock in [definitions.RegWriteLock.NO, definitions.RegWriteLock.FRW, definitions.RegWriteLock.FRU])) or \
                       ((lock == definitions.LockTest.AB ) and (item.register_write_lock in [definitions.RegWriteLock.NO, definitions.RegWriteLock.FRW, definitions.RegWriteLock.FRU])) or \
                       ((lock == definitions.LockTest.ABC) and (item.register_write_lock in [definitions.RegWriteLock.NO, definitions.RegWriteLock.FRW, definitions.RegWriteLock.FRU, definitions.RegWriteLock.FEBU])):
                        check = "CHECK"
        self.checked = str(check) # set the value
        
    def get_status_type(self):
        print(self.checked) # get the value
        if self.check = "CHECK_NRF"
            status_value = 8'h44
        else:
            status_value = 8'h40
        return status_value
