I want to print something on a label whenever user inputs a space. But my code only prints a line when space is entered first time and not after that.
Here is my code:
from tkinter import *
#LOOP_ACTIVE = True
def func1(self):
lsum["text"] = "space entered"
#root.after(0, func1)
root = Tk()
T = Text(root, height=20, width=30)
T.pack(side=RIGHT)
T.grid(row=0, column=1)
T.insert(END, "Just a text Widget\nin two lines\n")
v = IntVar()
a=Radiobutton(root, text="unigram", variable=v, value=1).grid(column=0,row=0)
b=Radiobutton(root, text="bigram", variable=v, value=2).grid(column=0,row=1)
c=Radiobutton(root, text="trigram", variable=v, value=2).grid(column=0,row=2)
T.bind("<space>",func1)
lsum = Label(root)
lsum.grid(row=0, column=2, sticky=W, pady=4)
root.mainloop()
Please Help!
Just added a counter, for you to see that your code works
from tkinter import *
#LOOP_ACTIVE = True
count = 1
def func1(self):
global count
count += 1
lsum["text"] = "space entered" + str(count)
#root.after(0, func1)
root = Tk()
T = Text(root, height=20, width=30)
T.pack(side=RIGHT)
T.grid(row=0, column=1)
T.insert(END, "Just a text Widget\nin two lines\n")
v = IntVar()
a=Radiobutton(root, text="unigram", variable=v, value=1).grid(column=0,row=0)
b=Radiobutton(root, text="bigram", variable=v, value=2).grid(column=0,row=1)
c=Radiobutton(root, text="trigram", variable=v, value=2).grid(column=0,row=2)
T.bind("<space>",func1)
lsum = Label(root)
lsum.grid(row=0, column=2, sticky=W, pady=4)
root.mainloop()

When the "view" button is pressed, it should trigger the function solution(i) such that label should be displayed in the new window. The problem is that the window opens and the previous label is packed but the label which gets it's text from "i" does not gets packed, Is there any issue in passing the parameter.
Any help is appreciated.
root = Tk()
root.config(background = "#303939")

I don't know how to return or print result to entry widget. I've tried to add code on the res function, but it still doesn't return the result that I want.
import tkinter as tk
from tkinter import *
win = tk.Tk()
win.title("Test")
win.configure(background='black')
enternumber = Label(win, text="Enter Number")
enternumber.grid(column=0, row=0)
var1 = IntVar()
txtenternumber = Entry(win, width=20, textvariable=var1)
txtenternumber.grid(column=1, row=0)
enternumber = Label(win, text="Enter Number")
enternumber.grid(column=0, row=1)
var2 = IntVar()
txtenternumber = Entry(win, width=20, textvariable=var2)
txtenternumber.grid(column=1, row=1)
def res():
result = var1.get()*var2.get()
#here the code i added
resultentry.bind('<Return>', res)
#Here the button should returning result
resultbutton = Button(win, text="Ok", command=res)
resultbutton.grid(column=2, row=2)
resultlabel = Label(win,text="Result")
resultlabel.grid(column=0, row=2)
#I want result printed here
resultentry = Entry(win, width=30)
resultentry.grid(column=1,row=2)
import tkinter as tk
from tkinter import *
win = tk.Tk()
win.title("Test")
win.configure(background='black')
enternumber = Label(win, text="Enter Number")
enternumber.grid(column=0, row=0)
var1 = IntVar()
txtenternumber = Entry(win, width=20, textvariable=var1)
txtenternumber.grid(column=1, row=0)
enternumber = Label(win, text="Enter Number")
enternumber.grid(column=0, row=1)
var2 = IntVar()
txtenternumber = Entry(win, width=20, textvariable=var2)
txtenternumber.grid(column=1, row=1)
def res():
result = var1.get()*var2.get()
resultentry.insert(0,result) # INSERTS RESULT INTO resultentry
resultentry.bind('<Return>', res)
resultbutton = Button(win, text="Ok", command=res)
resultbutton.grid(column=2, row=2)
resultlabel = Label(win,text="Result")
resultlabel.grid(column=0, row=2)
resultentry = Entry(win, width=30)
resultentry.grid(column=1,row=2)
win.mainloop()
Sorry, forgot to add this. Yes, you just need to use resultentry.insert(0, result)and you should be set. I also like using this as a good resource:

Why doesn't my code print anything when I press a radiobutton and then the submit button? For example, if I press the "Open Save" radiobutton, leave the entry blank and press submit it should print "test2", but it doesn't print anything no matter what I do.
def Saves():
global saveordelete
saveordelete = 0
global savedname
def openthesave():
saveordelete = 1
def deletethesave():
saveordelete = 2
def opensave():
if saveordelete == 1:
openname = savedname.get() + ".txt"
my_file = Path(openname)
if my_file.is_file():
print("tes1")
else:
print("test2")
elif saveordelete == 2:
openname = savedname.get() + ".txt"
my_file = Path(openname)
if my_file.is_file():
print("test3")
else:
print("test4")
root = Tk()
root.title("Saves")
root.iconbitmap("morseicon.ico")
root.resizable(0,0)
Label(root, text="Name:").grid(row=0, column=0, sticky=W)
savedname = Entry(root, width=20)
savedname.grid(row=0, column=1)
Button(root, text="Submit", width=10, command=opensave, bg="aqua").grid(row=3, column=8)
Label(root, text="Choose kind:").grid(row=1, column=0, sticky=W)
Radiobutton(root, text="Open save", height="1", command=openthesave, value=1).grid(row=2, column=0, sticky=W)
Radiobutton(root, text="Delete save", height="1", command=deletethesave, value=2).grid(row=3, column=0, sticky=W)
root.mainloop()
saveordelete is a local variable in the functions openthesave() and deletethesave(). They do not change the value of the global saveordelete defined in Saves(). Either mark it as global in both functions, or (better) use a class.
I am making a quiz in python using the tkinter module and I am stuck on how to create a button that checks to see if the answer is correct or not. But I would put it in a procedure however the question is already in one.
import tkinter as tk
window = tk.Tk()
window.title("6 Questions")
window.geometry("500x150")
score = 0
def inst():
t = tk.Label(window, text="All you need to do is just answer each question with either a '1, 2, 3' or the actual word.")
t.pack()
def start():
root = tk.Tk()
root.title("question 1")
q = tk.Label(root, text="what type of input holds whole numbers")
q.pack()
a = tk.Label(root, text="1.) int")
a.pack()
b = tk.Label(root, text="2.) string")
b.pack()
c = tk.Label(root, text="3.) float")
c.pack()
ans = tk.Entry(root, width=40)
ans.pack()
#here is the button I want to verify the answer
sub = tk.Button(root, text="Submit")
sub.pack()
greet = tk.Label(window, text="Welcome to the 6 Question Quiz.")
greet.pack()
start = tk.Button(window, command=start, text="Start")
start.pack()
instr = tk.Button(window, text="Instructions", command=inst)
instr.pack()
end = tk.Button(window, text="Exit", command=exit)
end.pack()
Create a function that opens when the submit button is clicked and create RadioButtons rather than Labels.
Like this:
def gettingDecision():
if var.get() is 'True':
messagebox.showinfo('Congrats', message='You Are Correct.Score is {}'.format(score))
else:
messagebox.showinfo('Lose', message='You Are Wrong.')
Question1 = ttk.Label(frame1, text='Q.1.Where does a computer add and compare data ?')
Question1.grid(row=1, column=0, sticky=W)
var = StringVar()
Q1A = ttk.Radiobutton(frame1, text='[A] Hard disk', variable=var, value='False1')
Q1A.grid(row=2, column=0, sticky=W)
Q1B = ttk.Radiobutton(frame1, text='[B] Floppy disk', variable=var, value='False2')
Q1B.grid(row=3, column=0, sticky=W)
Q1C = ttk.Radiobutton(frame1, text='[C] CPU chip', variable=var, value='True')
Q1C.grid(row=4, column=0, sticky=W)
Q1D = ttk.Radiobutton(frame1, text='[D] Memory chip', variable=var, value='False3')
Q1D.grid(row=5, column=0, sticky=W)
submit = ttk.Button(frame1, text='Submit', command=gettingDecision)
submit.grid()
Please note that, ideal way to go would be using classes.
You can define a function, inside of a function.
import tkinter as tk
window = tk.Tk()
window.title("6 Questions")
window.geometry("500x150")
score = 0
def inst():
t = tk.Label(window, text="All you need to do is just answer each question with either a '1, 2, 3' or the actual word.")
t.pack()
def start():
def submit():
print (ans.get())
#or do whatever you like with this
root = tk.Tk()
root.title("question 1")
q = tk.Label(root, text="what type of input holds whole numbers")
q.pack()
a = tk.Label(root, text="1.) int")
a.pack()
b = tk.Label(root, text="2.) string")
b.pack()
c = tk.Label(root, text="3.) float")
c.pack()
ans = tk.Entry(root, width=40)
ans.pack()
#here is the button I want to verify the answer
sub = tk.Button(root, text="Submit", command=submit)
sub.pack()
greet = tk.Label(window, text="Welcome to the 6 Question Quiz.")
greet.pack()
startButton = tk.Button(window, command=start, text="Start")
startButton.pack()
instr = tk.Button(window, text="Instructions", command=inst)
instr.pack()
end = tk.Button(window, text="Exit", command=window.destroy)
end.pack()
window.mainloop()
I would like to know how to create a dynamic button that calls the function selected in a OptionMenu Widget.
In the penultimate line [-2], I substituted "command=daily_return" by "command=var" but it does not work.
Any suggestions?
Best

Sometimes the simplest solution is Good Enough:
def do_something():
# define a mapping from the choice value to a function name
func_map = {
"daily_choices": daily_choices,
"value_at_risk": value_at_risk,
"cumulative_return": cumulative_return,
}
# using the map, get the function
function = func_map[var.get()]
# call the function
function()
...
Button(..., command=do_something)
