使用 tkinter 中的按钮启动另一个脚本

Question

我正在尝试使用 tkinter 中的按钮在脚本中运行另一个脚本

我尝试了两种方法，一种是

import os

class SeaofBTCapp(tk.Tk):
    #initilization
    def __init__(self, *args, **kwargs):      
        tk.Tk.__init__(self, *args, **kwargs)
        tk.Tk.wm_title(self, "Battery Life Calculator")
        container = tk.Frame(self)
        container.pack(side="top", fill="both", expand = True)
        container.grid_rowconfigure(0, weight=1)
        container.grid_columnconfigure(0, weight=1)
        self.frames = {}
        for F in (StartPage, PageOne, PageTwo, PageThree):
            frame = F(container, self)
            self.frames[F] = frame
            frame.grid(row=0, column=0, sticky="nsew")
        self.show_frame(StartPage)


#raise each page to the front
    def show_frame(self, cont):
        frame = self.frames[cont]
        frame.tkraise()

    def helloCallBack():
        os.system('python test2.py')

#the start page        
class StartPage(tk.Frame):

    def __init__(self, parent, controller):
        tk.Frame.__init__(self,parent)
        label = ttk.Label(self, text="Start Page", font=LARGE_FONT)
        label.pack(pady=10,padx=10)
        button = ttk.Button(self, text="Visit Page         1",command=lambda:controller.show_frame(PageOne))                  
        button.pack()
        button1 = ttk.Button(self, text="Visit Page 2",command=lambda:controller.show_frame(PageTwo))                 
        button1.pack()
        button2 = ttk.Button(self, text="Visit Graph page",command=lambda:controller.show_frame(PageThree))              
        button2.pack()
        button3 = ttk.Button(self, text="execute test",command=lambda:controller.helloCallBack)               
        button3.pack()

没有给出错误，但是当我点击执行时没有任何反应

我尝试的另一种方法是

import test2

但它会自动运行脚本并打印“我是一个测试”

我应该注意我试图调用的脚本只是一个测试，只是打印“我是一个测试”

感谢任何帮助！

谢谢

app = SeaofBTCapp()
app.mainloop()

test2.p如下

def main():

    if __name__ == "__main__":
        print("Executing as main program")
        print("Value of __name__ is: ", __name__)
        main()

Answer 1

不建议您使用第一种方法。如果你有另一个 python 脚本，你一定要导入它。

关于第二种方法：
我的猜测是脚本test2.py 没有写

if __name__ == "__main__":
    main()

这就是为什么它会在您导入时向您发送消息。
