        self.labeltitle = Label(root, text="",  fg="black", font="Helvetica 40 underline bold")
        self.labeltitle.pack()

        self.labelstep = Label(root, text="",  fg="black", font="Helvetica 30 bold")
        self.labelstep.pack()

        self.labeldesc = Label(root, text="",  fg="black", font="Helvetica 30 bold")
        self.labeldesc.pack()

        self.labeltime = Label(root, text="",  fg="black", font="Helvetica 70")
        self.labeltime.pack()

        self.labelweight = Label(root, text="",  fg="black", font="Helvetica 25")
        self.labelweight.pack()

        self.labelspeed = Label(root, text="",  fg="black", font="Helvetica 20")
        self.labelspeed.pack()

        self.labeltemp = Label(root, text="", fg="black", font="Helvetica 20")
        self.labeltemp.pack()

        self.button = Button(root, text='Close recipe', width=25, command=root.destroy)
        self.button.pack()

    def Update(self, label, change):
        label.config(text=str(change))

I'm trying to create a recipe display which will show the step, instructions, weight and other variables on a screen in a Tkinter GUI.

However, I do not know how to update the GUI to change with each new step of the recipe, as the content has to be dynamically updated based on user input (taken from a server). How can I achieve updating of the GUI's other elements based on the change in steps?

You can use after() to run function after (for example) 1000 miliseconds (1 second) to do something and update text on labels. This function can run itself after 1000 miliseconds again (and again).

It is example with current time

from Tkinter import *
import datetime

root = Tk()

lab = Label(root)
lab.pack()

def clock():
    time = datetime.datetime.now().strftime("Time: %H:%M:%S")
    lab.config(text=time)
    #lab['text'] = time
    root.after(1000, clock) # run itself again after 1000 ms

# run first time
clock()

root.mainloop()

BTW: you could use StringVar as sundar nataraj Сундар suggested

Using .config() to Update Widgets, from Tkinter import * import time #Tkinter stuff class App(object): def __init__(self) : self.root = Tk() self.labeltitle = Label(root, text="", fg="black", font="Helvetica 40� Understand the Tkinter code. Create frames, labels, buttons, binding functions, events and all. To develop simple GUI apps. So next up on this Tkinter Tutorial blog, we’re going to create a simple Calculator GUI with all the stuff that we’ve learned till now.

if you want to change label dynamically

self.dynamiclabel=StringVar()
self.labeltitle = Label(root, text=self.dynamiclabel,  fg="black", font="Helvetica 40 underline bold")
self.dyanamiclabel.set("this label updates upon change")
self.labeltitle.pack()

when ever you get new value then just use .set()

self.dyanamiclabel.set("Hurrray! i got changed")

this apply to all the labels.To know more read this docs

How to update the gui in a loop without blocking the , In this video I'll show you how to use .config() to update just about after this tkinter Duration: 8:00 Posted: Apr 28, 2020 Create a GUI in Python using tkinter. To start, I’ll share the complete code that you can paste into Python in order to create the above tkinter GUI. I’ll then explain the main parts of the code.

If you are using labels, then you can use this:

label = tk.Label(self.frame, bg="green", text="something")
label.place(rely=0, relx=0.05, relwidth=0.9, relheight=0.15)

refresh = tk.Button(frame, bg="white", text="Refreshbutton",command=change_text) 
refresh.pack(rely=0, relx=0.05, relwidth=0.9, relheight=0.15)

def change_text()
   label["text"] = "something else"

Works fine for me, but it is dependent on the need of a button press.

Labels in Tkinter (GUI Programming), I have a Raspberry pi and using Python I've wrote a GUI to control a fan using PWM and to work out the RPM from the fans pulsed output.
