Tkinter - "Label" object is not callable ; NOT a case of naming an object after LABEL class [duplicate]

This question already has answers here:
I'm getting a TypeError. How do I fix it?

TypeError: 'function' object is not subscriptable - Python
(4 answers)
Closed 6 months ago.
I'm working on a tkinter GUI API-based application.
I'm attempting to modularize my code in which each function has a specific task to do and some functions just call other functions.
In my case, I bind the search button to the function, search, whose job is to call other API-based functions, such as full_name.
When I did this, an error is thrown, saying that in search full_name() TypeError: 'Label' object is not callable
what's interesting is that
I see no mention of creating instances of Label classes in full_name()
when I bind the search button to function, full_name(), it works just fine. However, I want to bind it to a function that will call all API-based functions, and so far, it's not working
Here's the code below:

Feel free to ask for more clarity. I would be grateful if anyone has a reason/solution

You have used the same name for a label:
full_name = Label(left_frame, text = "Full Name :")
So it will override the full_name().
Use another name for the label, for example full_name_label:
full_name_label = Label(left_frame, text = "Full Name :")
full_name_label.grid(row = 1, column = 0, sticky = W)

Python - tkinter - tree - database questions

I have a database with a customers table with the fields(id, name,surname, DOB).
I have created a treeview which displays name and surname but soon as i try to insert the DOB in to the treeview i get an error Column index 3 out of bounds.
Also please can you explain how treeview actually works as i have copied the code from a tutorial and adapted it but still dont fully understand it.

Python Status Bar

I am having a problem with adding status bar at the bottom of my program. When I do status.pack() it gives me this error : _tkinter.TclError: cannot use geometry manager grid inside . which already has slaves managed by pack. In My (
def init(self): ) If I delete (self.grid(sticky = W+E+N+S) then the window pops up an then the status bar is on the window, but then the rest of the program isn't there. I was wondering if someone give some insight on how to fix this

I'm exactly sure on how to upload the gif file with this code.

The error message is telling you what's wrong. If you have already used one geometry manager within a widget you cannot use another.
e.g. - You cannot use both pack and grid within a frame. You must use one or the other.
You could make another widget and then use the seperate geometry manager within this widget but you would have to use the original manager to place it within the master widget.

Python: I am working on a Restaurant tip calculator, I am trying to integrate radio buttons

There is no self.percVar in your code. As #wastl said, you need to initialize it.
To do that, you need to use one of the variable classes. Since you are using float type, DoubleVar() would be the best.
def addPercTip(self):
self.percVar = DoubleVar() #this line should be added in your method
Label(self, text = "% of Tip",
font = self.headerFont).grid(row = 3, column = 0)
def selected(self):
print (type(self.percVar.get()))
#which is float, without converting explicitly because of DoubleVar()
print (self.percVar.get())
#this will print what you click

You forgot to intialize the self.percVar variable
Add self.percVar = 0 as the first line of the addPercTip method. That should fix your error.
BTW: For future questions the best thing is to include the error message you get and EXACTLY describe what part of the programm causes what kind of trouble for you

How do I validate an entry widget in python?

I'm creating a GUI using Tkinter that is used to collect information from a user. I need to validate:
First and Last name only contain letters, apostrophes, and dashes
Address
Phone number has the correct number of digits
Valid birthday (Feb 31 doesn't exist and birth year between 1900 and 2014)
Email address contains '#' and '.'
Here is my code:

# Create pulldown menu and add to menu bar
messagesMenu = Menu(menubar, tearoff = 0)
menubar.add_cascade(label = "Messages", menu = messagesMenu)
messagesMenu.add_command(label = "Send a Birthday Greeting", command = self.bdayGreeting)
messagesMenu.add_command(label = "Print Address", command = self.printAddress)
# Create another menu option
endMenu = Menu(menubar, tearoff = 0)

endMenu.add_command(label = "Reset Form", command = self.resetForm)
endMenu.add_command(label = "Exit Program", command = window.quit)

I have a couple questions.
Starting from def validFirst(self), how do I validate the different entry fields? I keep getting NameError: name "asdf" is not defined, SyntaxError: unexpected EOF while parsing, and TypeError: 'int' object is not subscriptable when I modify the code and I'm still stuck on validFirst(self).
I have a set of labels in column 3 reserved for error messages: errorLblFirst = Label(window, text = " ", fg = "red").grid(row = 1, column = 3). Is it possible to set it to " * Invalid Entry", fg = "red" when the validation for that entry fails? Is there another way to get error messages to show?
Thanks in advance for the input!
Edit: I updated to my latest code. Most of the validation works now except for validBday and validEmail if you could check it out.

errorLblFirst = Label(...).grid(...)
This way you assign result of grid() to errorLblFirst but grid() always returns None
Always do it this way
errorLblFirst = Label(...)
errorLblFirst.grid(...)
And now you can do (for example)
errorLblFirst["text"] = " * Invalid Entry"
errorLblFirst["fg"] = "red"
EDIT:
You forgot len() in for i in range(first): in validFirst()
And you don't need eval().
(You got the same problem in validPhone())
F = 0
fName = True
first = self.firstName.get() # without eval()
for i in range(len(first)): # len()
if first[i].isdigit():
F += 1
if F > 0:
return False
else:
return fName
return fName
but you could do this shorter
for letter in self.firstName.get():
if letter.isdigit():
return False
return True
if you need only letters (no space, commas, etc.) you could do this
return self.firstName.get().isalpha()
EDIT:
I see First Name can have apostrophes, and dashes
for letter in self.firstName.get():
if not letter.isalpha() and letter not in "'-":
return False
return True
EDIT: problem with self.phone and StringVar
self.phone is StringVar() - not string
but StringVar() has .get() to get string
for number in range(len( self.phone.get() )):
By the way: you can do for loop more pythonic - without range(len())
for char in self.phone.get():
if char.isdigit():
EDIT: problem with validEmail() and validBday()
Email validation needs more if.
For example you could add
email = self.email.get()
if '#' not in email and '.' not in email::
print( 'email needs # and . at the same time')
but '.#' will pass this test :/
Real email validation is more complicated.
See valid email examples: https://fightingforalostcause.net/content/misc/2006/compare-email-regex.php
self.bday is StringVar - use self.bday.get() in place of str(self.bday)
EDIT:
def validPhone(self):
D = 0
for number in self.phone.get():
if number.isdigit():
D += 1
# outside
if D == 10:
return True
else:
self.errorLblPhone["text"] = " * Must be 10-digit phone number without spaces"
return False
return True
or even
def validPhone(self):
# remove previous error message
self.errorLblPhone["text"] = ""
D = 0
for number in self.phone.get():
if number.isdigit():
D += 1
if D != 10:
self.errorLblPhone["text"] = " * Must be 10-digit phone number without spaces"
return False
return True
If number can have only 10 digits (no space, no - , etc):
def validPhone(self):
# remove previous error message
self.errorLblPhone["text"] = ""
D = True
for number in self.phone.get():
if not number.isdigit():
D = False
break
if not D or len(number) != 10:
self.errorLblPhone["text"] = " * Must be 10-digit phone number without spaces"
return False
return True
