I decided to make a tkinter timer but am receiving a very strange error.
Here is the code and the error:
import tkinter as tk
import time
window = tk.Tk()
window.title("Hello wold")
window.geometry("300x300")
timer = int(input("time in seconds"))
for i in range(timer):
timer -= 1
print(timer)
time.sleep(1)
hello = tk.Label("timer")
hello.pack()
tk.mainloop()
The error:
Traceback (most recent call last):
File "main.py", line 14, in <module>
hello = tk.Label("timer")
File "/usr/lib/python3.8/tkinter/__init__.py", line 3143, in __init__

File "/usr/lib/python3.8/tkinter/__init__.py", line 2561, in __init__
BaseWidget._setup(self, master, cnf)
File "/usr/lib/python3.8/tkinter/__init__.py", line 2530, in _setup
self.tk = master.tk
AttributeError: 'str' object has no attribute 'tk'
To change the text of a label you need to define the text property:
hello = tk.Label(text="timer")
This will set the text of the label to "timer", but if you want to set it as the variable you previously declared (called timer) - simply remove the quotation marks.
hello = tk.Label(text=timer)
This will set the text of the label to whatever the variable 'timer' is equal to.
However you also need to set the window, which leaves the final code to this:
hello = tk.Label(window, text=timer)
I added tk.StringVar in line 16.
I added textvariable=string_variable in line 17
tk.mainloop was relocated outside of the loop block in line 20
Here is code:
import tkinter as tk
import time
window = tk.Tk()
window.title("Hello wold")
window.geometry("300x300")
timer = int(input("time in seconds"))
for i in range(timer):
timer -= 1
print(timer)
time.sleep(1)
string_variable = tk.StringVar(window, timer)
hello = tk.Label(window, textvariable=string_variable)
hello.pack()
tk.mainloop()
Output result:

The following is a simple tkinter program that displays an empty window:
# firstTkinter2.py
from Tkinter import Tk, Label
top = Tk()
l = Label(top, "Hello World")
l.pack()
# Give the window a title.
top.title("My App")
# Change the minimum size.
top.minsize(400, 400)
# Change the background colour.
top.configure(bg = "green")
# Run the widget.
top.mainloop()
I run the above code but it encountered an error:
zhiwei#zhiwei-Lenovo-Rescuer-15ISK:~/Documents/python programs/tkinter$ python tk2.py
Traceback (most recent call last):
File "tk2.py", line 4, in <module>

File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 2094, in __init__
for k in cnf.keys():
AttributeError: 'str' object has no attribute 'keys'
How can I fix this error and let it run properly?
Try to replace:
l = Label(top, "Hello World")
on
l = Label(top, text="Hello World")
# ^^^^^^^
Use Label(top, text="Hello World")
You have to use the text argument.
I'm trying to insert a gif image in a new tkinter window when a button is clicked but I keep getting this error

Here's the code. The image and the location actually exists.

photo = tkinter.PhotoImage(file = 'American-Crime-Story-1.gif')
self = photo
canvas = tkinter.Label(wind,image = photo)

def base():
ssw = tkinter.Tk()
la = tkinter.Button(ssw,text = 'yes',command=six)
la.grid()
base()
What am I doing wrong?
You are trying to create two instances of Tk window. You can't do that. If you want second window or pop-up window you should use Toplevel() widget.
Also, self doesn't mean anything in this context. Using the widget's image property would be better to keep a reference.
import tkinter
ssw = tkinter.Tk()
def six():
toplvl = tkinter.Toplevel() #created Toplevel widger
photo = tkinter.PhotoImage(file = 'American-Crime-Story-1.gif')
lbl = tkinter.Label(toplvl ,image = photo)
lbl.image = photo #keeping a reference in this line
lbl.grid(row=0, column=0)
def base():
la = tkinter.Button(ssw,text = 'yes',command=six)
la.grid(row=0, column=0) #specifying row and column values is much better
base()
ssw.mainloop()
I'm trying to add a ttk calendar into my Tkinter GUI. The problem is that it raises _tkinter.TclError: can't pack .34164128 inside .34161248.34161448.34161608

Do you know where is the problem?
The fault is that you don't have an __init__ method in the class CalendarDialog. So just rename the body method to __init__. Now you have initialized the instance every time one is made and a pack() method is defined.
I also encountered this problem putting a ttkCalendar into a Dialog box.
I suspect the author of this post "borrowed" the same code for building a calendar as I did:
https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=2ahUKEwiWgYWKsJ3nAhVKl3IEHYrhCU8QFjABegQICBAB&url=https%3A%2F%2Fsvn.python.org%2Fprojects%2Fpython%2Ftrunk%2FDemo%2Ftkinter%2Fttk%2Fttkcalendar.py&usg=AOvVaw0ifTox4EI7CtBFWlRYD_m9
There are two problems I found using this code to create a Calendar object and placing it into a Dialog box.
The first one causes the traceback as shown in the post. The fix is to modify the ttkcalendar.py file to pack the calendar when it is created, not after it is created using the pack() function.
Here is the diff:
102c102
< self._calendar = ttk.Treeview(show='', selectmode='none', height=7)
---
> self._calendar = ttk.Treeview(self, show='', selectmode='none', height=7)
109c109
< self._calendar.pack(in_=self, expand=1, fill='both', side='bottom')
---
> self._calendar.pack(expand=1, fill='both', side='bottom')
Once you make this change, the calendar will appear in the dialog box. However, your problems are not yet done. Another exception occurs when trying to set the minimum size of the calendar:

I am writing a turtle and Tkinter program to display a screen wide canvas to set one dot on which I will then put through a loop, can someone please read my code. Here it is with the error:
import turtle
import Tkinter
root = Tkinter.Tk()
screen_width = root.winfo_screenwidth()
screen_height = root.winfo_screenheight()
cv = Tkinter.Canvas(root,width=screen_width,height=screen_height)
t = turtle.RawTurtle(cv)
screen = t.getscreen()
frame = Tkinter.Frame(root)
def main():
root.title("Scanner")
cv.pack()
screen.setworldcoordinates(0,0,screen_width,screen_height)
screen.bgcolor("black")
frame.pack()
Tkinter.mainloop()
def setDefaultPos():
t.penup()
t.goto(80,80)
if __name__ == "__main__":
main()
setDefaultPos()
t.dot(1, "white")

_tkinter.TclError: invalid command name ".3072604172L"
I also get other errors complaining that "white" is a bad string in respect to t.dot. Please help.
There are two things to fix your code.
First, your drawing happen after mainloop (once you have exited your window), you can fix it my either drawing before the call of root.mainloop, either using a callback to be called during the mainloop.
def callback():
setDefaultPos()
t.dot(1, "white")
#(...)
root.after(1, callback) #call 'callback' function after 1 millisecond
Tkinter.mainloop()
Second, the diameter you ask for (1 pixel) makes your dot not visible...
I'm new to python. I'm trying to open a dialog box to get a value from within a widget that does a list of other staff allready.
But getting errors and can't figure out what to do.

So as may be apparent to you, I'm importing dataset with an Import button, executing some analysis in another code through a button called Execute, and then showing some graphs.
What I wanted was to open a pop up kind of window on click of "Execute" button that will input a value. But I'm getting the following error:
Exception in Tkinter callback

I've no idea what to do. Please help.
When you create the toplevel widget, you are passing self as the first argument. Tkinter requires that this be a parent widget. However, in your code self does not represent a widget.
In your specific case you want to pass in self.mymaster rather than self:
top = self.top = Tkinter.Toplevel(self.mymaster)
Use Tkinter.Toplevel() instead of Tkinter.Toplevel(self)
