making an email slicer,
some errors I'm getting are:
AttributeError: 'bool' object has no attribute 'index'
ValueError: substring not found
now, with this specific code, I'm getting no result at all, it just doesn't do anything when I click the button
root = Tk()
e = Entry(root)
e.grid(row = 6, column = 6)
s = Label(root)
s.grid(row = 1, column = 1)
wel = Label(root, text = "whats your email")
wel.grid(row = 1, column = 5)
inp = Entry(root)
inp.grid(row = 3, column = 5)
def callback(re = inp.get()):
us = re[:re.startswith("#")]
uss = re[re.startswith("#")+1:]
var = StringVar()
var.set(us + uss)
sub = Button(root, text = "submit", command = lambda:callback())
sub.grid(row = 5, column = 5)
final = Label(root, textvariable = var)
final.grid(row = 5, column = 6)
root.mainloop()
You need to
call inp.get() inside callback(), not as default value of argument
use find() instead of startswith()
call var.set(...) inside the function as well
def callback():
re = inp.get()
pos = re.find("#")
if pos >= 0:
user = re[:pos]
domain = re[pos+1:]
var.set(user+","+domain)
else:
var.set("Invalid email")
Note that above is not enough to check whether the input email is valid or not, for example two "#" in the input.

In this simple calculator GUI, I'm creating a frame template using classes. The frame has 2 labels, 2 entry boxes, and a button. I'd like the button to run a specific command depending on the function_call variable passed when initializing - but this doesn't work. The two_points function should be called for the first object, and one_point should be called for the second. How do I dynamically change which command is called based on which object I'm using? Thank you for taking the time to read this.

The command keyword argument of the Button constructor is supposed to be a function.
Here you give it instead a string which is the name of the method of self that should be called. So you must first get this method using setattr to be able to call it. This should do it:
def call():
method = getattr(self, self.function_call)
method()
self.calc_button = Button(
self.frame_1,
text = "Calculate",
command = call)
You then have an error in strip_string but that's another story.
I have the following code (it's partly in Dutch but I don't think that'll be an issue):
from tkinter import *
root = Tk()
woorden_en = ["mouse", "armadillo", "caterpillar", "buffalo", "dragonfly", "eel", "monkey", "lark", "manatee", "squid"]
woorden_nl = ["muis", "gordeldier", "rups", "buffel", "libelle", "paling", "aap", "leeuwerik", "zeekoe", "inktvis"]
nummer = IntVar()
nlWoord = StringVar()
enWoord = StringVar()
goedfout = StringVar()
def vorige():
nummer -= 1
def volgende():
nummer += 1
def controleer():
print("Correct!")
secondGrid = Frame(root)
secondGrid.grid(row = 2, column = 1, columnspan = 2)
labelVertaling = Label(root, text="vertaling")
textVertaling = Entry(root, width=30, textvariable = nlWoord)
runVorige = Button(secondGrid, text="vorige", command = vorige)
runVolgende = Button(secondGrid, text="volgende", command = volgende)
runControleer = Button(secondGrid, text="controleer", command = controleer)
labelWoord = Label(root, text="woord")
labelWoordEn = Label(root, textvariable = enWoord)
labelNo = Label(root, textvariable = nummer)
Correct = Label(root, textvariable = goedfout)
Correct.grid(row = 2, column = 0)
labelNo.grid(row = 0, column = 0)
labelWoord.grid(row = 0, column = 1)
labelWoordEn.grid(row = 1, column = 1)
labelVertaling.grid(row = 0, column = 2)
textVertaling.grid(row = 1, column = 2)
runVorige.grid(row = 0, column = 0, sticky = "W")
runVolgende.grid(row = 0, column = 1, sticky = "W")
runControleer.grid(row = 0, column = 2, sticky = "W")
nummer.set(1)
enWoord.set(woorden_en[0])
root.mainloop()
The start value of 'nummer' is 1, as set in the 3rd to last line. This value needs to be changed with either -1 or +1 when clicking buttons 'vorige' (previous) or 'volgende' (next). The current code in the functions give me erros. Apparently I need to use set/get functions, but I cannot find out how to make it work. Any input or help would be appreciated.
Just change your function to:
def vorige():
nummer_val = nummer.get()
nummer_val -= 1
nummer.set(nummer_val)
def volgende():
nummer_val = nummer.get()
nummer_val += 1
nummer.set(nummer_val)
This is because nummer is an IntVar() and you have to get the value of the variable using get() method. After that you have to assign it to a variable and then reduce/increase its value by 1. The first error you were getting was because the nummer was not globalized inside the function, but that was not the approach you should have taken, anyway this should fix your errors.
I have 2 sets of radio buttons to be selected, if I select one of the second set, the selected button in the first set will be de-selected, although the related function is still working.
Here is the example and code
For “Need Specific Number?” (radio 1 and radio 2) and “Want to Send email with different email address?”(radio 5 and radio 6), I can only select 1 of them. for example, if I select radio 1, then select radio 5 or radio 6, radio 1 is de-selected. I am not sure where I did wrong.
Could you kindly point out the correct way?
Here is my code

You have not assigned a variable to the first and third row of radiobuttons. If I interrogate the radiobuttons without a variable they say they are bound to selectedButton, which is the same for all of them. I'm guessing this is some kind of default behaviour when variable is missing. If you create a variable for each of the rows of associated radiobuttons and assign it to them, the effect goes away.
Hey Guys I have a problem with checkboxen in tkinter. Can someone say where my fault is ?
def edit_contact_gui(self):
"""GUI to edit the created contacts."""
self.edit_contact_wd = tk.Tk()
self.edit_contact_wd.title('Edit Contacts of the Phonebook:"%s"'\
% self.book)
self.button_edit = tk.Button(self.edit_contact_wd, text = 'Edit',\
command = self.edit_contact)
try:
with open('%s.txt' % self.book, 'rb') as file:
book = pickle.load(file)
x = 1
self.var_lst = []
for i in book:
var = tk.IntVar()
tk.Label(self.edit_contact_wd, text = i).grid(row = x, \
column = 0)
tk.Checkbutton(self.edit_contact_wd, text = 'edit', \
variable = var).grid(row = x, column = 1)
self.var_lst.append(var.get())
x += 1
self.button_edit.grid(row = x+1, column = 1)
except FileNotFoundError:
tk.Label(self.edit_contact_wd, text = 'The phonebook has no entrys!', fg = 'red').grid(row = 1, column = 0)
self.edit_contact_wd.mainloop()
def edit_contact(self):
print(self.var_lst)
My GUI output works, but the programm return me a List [0,0,0,0,0] full of zeros. In my opinion the Checkbox who is marked has return a 1 but it doesnt to it. Why? Can you help me ?
You have to keep IntVar (var) on list, not value from IntVar (var.get())
self.var_lst.append(var) # without .get()
and in edit_contact() you have to use get()
for var in self.var_lst:
print(var.get())
Trying to show a green or red background in the text field of the answer to the simple addition quizzer.
Currently in PyCHarm complains that:
Entry.grid_configure(background = "red")
TypeError: grid_configure() missing 1 required positional argument: 'self'

I can't seem to figure this out. Any help is appreciated.
Here's the code so far:
from tkinter import *

window.title("Addition Quizzer") # Set the title
#window.width(len(window.title()))

Label(window, text = "+").grid(row = 2, column = 1, sticky = E)
Label(window, text = "Answer").grid(row = 3, column = 1, sticky = W)
self.firstNumber = StringVar()
Label(window, text = self.number1, justify = RIGHT).grid(row = 1, column = 2)
self.secondNumber = StringVar()
Label(window, text = self.number2, justify = RIGHT).grid(row = 2, column = 2)

If you had read and followed this in the Help Center material, you would have reduced your code to the following, which still gets the same error message.
from tkinter import *
Entry.grid_configure()
The message refers to the fact that Python instance methods require an instance. This is usually done by calling the method on an instance instead of the class. Otherwise, an instance must be given as the first argument. Consider
mylist = []
mylist.append(1)
list.append(mylist, 2)
print(mylist)
# [1, 2]
You need to save a reference to your Entry box. Change
Entry(window, ..., background = "grey").grid(...)
to
self.entry = Entry(window, ..., background = "grey").grid(...)
I do not know if calling .grid_configure(background=color will do what you want.
This will, I am sure.
self.entry['background'] = 'red'
