python中GUI学习label标签老是报错

from tkinter import *

class Application(Frame):
    ''' GUI程序的类的写法 '''
    def __init__(self,master=None):
        super().__init__(master)                # 这是父类的定义，而不是父类的对象
        self.master=master
        self.pack()
        self.createWidget()
    def createWidget(self):
        ''' 创建组件 '''
        self.label1=Label(self, test="超霸",width=10,height=2,
                          bg="blue",fg="white")
        self.label1.pack()
        self.label2=Label(self, test="恐龙",width=10,height=2,
                          bg="black",fg="white",font=("黑体",30))
        self.label1.pack()

if __name__=="__main__":
    root=Tk()
    root.geometry("300x300+300+300")
    root.title("GUI程序面向对象的测试")
    app=Application(master=root)
    root.mainloop()

明明跟上网课的写的一模一样，但是老是报错

怎么解决？

这是因为在创建Label组件时，你使用了错误的参数名称，应该是text而不是test。

修改代码如下：

self.label1 = Label(self, text="超霸",width=10,height=2,
                     bg="blue",fg="white")

self.label2 = Label(self, text="恐龙",width=10,height=2,
                     bg="black",fg="white",font=("黑体",30))

参数错了，是text
