[Tutor] Clock in tkinter?

[Mic]

Hi!
It is no homework, in fact am I working ahead of class. I have now, after five minutes thinking, solved my problem, but a new problem has risen.
But to begin with, here is how I solved the problem:



from tkinter import*
import time

the_time=''



class Window(Frame):
    def __init__(self,master):
        super(Window,self).__init__(master)
        self.grid()
        self.create_widgets()
        

    def create_widgets(self):

        #Create a hello button:
        hej=self.hellobttn=Button(self,text="Hey")
        self.hellobttn.grid(row=0, column=0)

        #Create a label that displays time:
        self.display_time=Label(self, text=the_time)
        self.display_time.grid(row=0, column=1)

        def change_value_the_time():
            global the_time
            newtime = time.strftime('%H:%M:%S')
            if newtime != the_time:
                the_time= newtime
                self.display_time.config(text=the_time, font="40")
            self.display_time.after(20, change_value_the_time)

        change_value_the_time()

root=Tk()
root.title("Test")
root.geometry("200x200")
app=Window(root)
root.mainloop()




I found some help on the internet about making a clock, although I had to modify a lot of the code to fit my own code and window.
Now to my next question. Say that I want a text “Hi, how are you?” to be printed when the time passes 15:00:00 each day. How do I do that?

At first I thought that I could just write an if statement. Like:

if the_time>15:00:00:
    print (“Hi, how are you?”)

But it is obviously not working.


Thank you for your help! Another question, am I supposed to add tutor at python.orgtutor@python.org; as copy? You did that, right?

  Hi!
  I am new to programming and I hop this question isn’t stupid.

Welcome! 

  I am making a small GUI program. It is supposed to have a button and a clock in it that displays the same time as it is according to the computer.
  So as far as I am concerned both the clock and the are supposed to be widgets?

Is this a homework assignment, or just something that you're doing for fun? It seems homework-ish. We don't mind pointing you in the right direction on homework assignments, but we definitely won't do it for you.

   So how do I add this clock as a widget placed next to the button? 

Tkinter doesn't have a native clock widget, so if you want to make a clock you need to roll your own.

   Here is the code I have written so far, that only displays a GUI window, and a button:
    
  from tkinter import *
  import time
    
  class Window(Frame):
      def __init__(self,master):
          super(Window,self).__init__(master)
          self.grid()
          self.create_widgets()

      def create_widgets(self):
          self.test_button=Button(self, text="Hi")
          self.test_button.grid(row=0,column=0)
          
  root=Tk()
  root.title("Test")
  root.geometry("200x200")
  app=Window(root)
  root.mainloop()

Giving us code (especially such a small amount) is exactly the right thing to do when you ask a question - it shows that you've tried something, and if it's broken it usually shows why it's broken.

You can add text to the Label widget - and you can change the text on that widget.

You're already importing the time module - for more information about what it contains, you can run the interactive interpreter and do this:

>>> import time
>>> help(time)

Or you can look online for the commands that might help you.

If you get stuck, let us know what you're doing and where you're stuck at.

HTH,
Wayne
