I am attempting to make a tkinter project but as I tried to run for like the third time it gives me this error:
Traceback (most recent call last):

(widgetName, self._w) + extra + self._options(cnf)
_tkinter.TclError: unknown option "-commmand"
What can I do to fix this? What are the problems with my code?
Here is my code:
https://pastebin.com/mWPEFbpz
You are spelling command wrong (three m's)
You are passing it a variable called commmand and it doesn't know how to use that variable.
tk.Button(... commmand = ...
You can see it in the error message right here
_tkinter.TclError: unknown option "-commmand"
These python error messages are actually very helpful. I would encourage you to read them carefully to catch stuff like this.

I'm trying to write a tkinter program, and I came across an error that I've never seen before while working with tkinter. I've searched around everywhere, and tried everything I can think of. This is my code so far:
x=tk.Canvas(top,width=1000,height=750,bg="grey")
x.pack()
y=tk.PhotoImage(file="C:\\Users\\Admin\\Desktop\\images (3)_CnyokaDvJmG1xu.png")
x.create_image(top,0,0,image=y)`
and this is error
Traceback (most recent call last):
File "C:\Users\Admin\Anaconda3\lib\tkinter\__init__.py", line
1705, in __call__
return self.func(*args)
File "C:/Users/Admin/.spyder-py3/temp.py", line 16, in open
x.create_image(top,0,0,image=y).pack()

return self._create('image', args, kw)
File "C:\Users\Admin\Anaconda3\lib\tkinter\__init__.py", line
2480, in _create
*(args + self._options(cnf, kw))))
_tkinter.TclError: bad screen distance "."
You don't have to supply containing widget when placing an image in a canvas, coordinates are enough:
x.create_image(0,0,image=y)
The error is because canvas does not accept a widget as coordinates.
I get this error from tkinter.Text():

The message is pretty clear, but I don't know where to start.
EDIT : I got this error when I tried to use matplotlib.pyplot.plot(). But this worked (no error anymore) for matplotlib. I didn't find a similar way to deal with tkinter.
I am not getting any kind of error with the same code, so I can't debug it. So, I think you should try the following:
from tkinter import *
root=Tk()
log = Text(root, state='disabled', width=80, height=24, wrap='none')
log.grid()
root.mainloop()
If it doesn't work and other widgets like, buttons and entries don't work then there is something wrong with the tkinter that you have installed. So, try to unistall and then, reinstall tkinter:
sudo apt-get remove python3-tk
sudo apt-get install python3-tk
If the above gives an error,use this link to check for your your version of linux, how to do it (refer to the comments also) :
Install tkinter for Python
Try it and let me know if that helps.
I am trying to show an image on screen with python and tkinter, but when I run it, it gives an error in the PhotoImage object.
This is my code:
from tkinter import *
root = Tk()
photo = PhotoImage(file="devil.png")
label = Label(root, image=photo)
label.pack()
root.mainloop()
The image file is in the same folder as the .py file.
And it gives this error:
Traceback (most recent call last):
File "C:/Users/MyUsername/PycharmProjects/GUI test/home.py", line 5, in <module>

self.tk.call(('image', 'create', imgtype, name,) + options)
_tkinter.TclError: encountered an unsupported criticial chunk type "iDOT"
Does anyone know how to fix this?
The chunk type of image you're using, 'iDOT', is not a registered PNG chunk. So, you should replace the image with an appropriate one.
This can help you understand what actually error is about
I have a label object that needs to display a variety of images. Based on my research, the following script (below) should successfully update the image displayed in my label object. However, when I call self.ImageViewer.configure(image=self.imgToDisp), I get a TypeError (seen below).
I'm not entirely sure what the error means, but it looks like .configure is expecting a string? Nobody else seems to encounter this problem so I must be doing something syntactically wrong with the script below. Any input is appreciated.
Script:
def getImgs(self):
folderPath = filedialog.askdirectory()
self.imgArray, self.imagePaths = batchImpt.importAllImgs(folderPath)
halThrThsnd.saveAllData(self.imgArray)
im = Image.open(self.imagePaths[0])
self.imgToDisp = PhotoImage(im)
self.imageViewer.configure(image = self.imgToDisp)
self.imageViewer.image = self.imgToDisp
Error:

TypeError: __str__ returned non-string (type TiffImageFile)
You need to change self.imgToDisp = PhotoImage(im) to self.imgToDisp = ImageTk.PhotoImage(im)
Of course, you must add ImageTk to your import statements. I think you already did: from PIL import Image. If So, modify it to: from PIL import Image, ImageTk.
Here I'm starting to create a TK window with a text field but when ever I run this I get the error

from within the module. What am I doing wrong? I'm realitively new to classes so I may have done something wrong in the class setup.
I'm running python 2.7 on OS 10.9
class emulator:
def __init__(self):
self.root=Tk()
self.root.geometry("500x500")
self.root.title("Python")
code=Text(self.root)
code.pack(self.root)
self.root.mainloop()
emulatorI=emulator()
The problem is with the line
code.pack(self.root)
The pack function normally takes no arguments except keyword arguments, and so should just be called as
code.pack()
The reason for the very odd error is that pack can take a positional argument, which is expected to be a dictionary of options. When trying to treat the Tk instance as a dictionary, it failed due to the lack of a __len__ method.
What is the purpose of code.pack(self.root)?
The arguments for pack are placement directions, such as side, padding, fill, anchor, etc
(see http://effbot.org/tkinterbook/pack.htm ).
