python可谓是啥都不懂，好难啊，求解

class Car:
    name = ''
    color = ''
    
    def __init__(self, name, color):
        self.name = name
        self.color = color
    
    def drive():
        print("汽车驾驶方法")
        
class Truck(Car):
    def __init__(self, name, color):
        self.name = name
        self.color = color
    
    def show_info(self):
        print("卡车名称: " + self.name + "、颜色：" + self.color)
