Python Tkinter Error

Question

I have tried to work with the Tkinter library, however, I keep getting this message, and I don't know how to solve it.. I looked over the net but found nothing to this specific error - I call the library like this:

from Tkinter import *

and I get this error -

    TclError = Tkinter.TclError
    AttributeError: 'module' object has no attribute 'TclError'

I have no clue what can I do now.. Thank you

full traceback:

Traceback (most recent call last):
File "C:/Users/Shoham/Desktop/MathSolvingProject/Solver.py", line 3, in <module>
from Tkinter import *
File "C:\Heights\PortableApps\PortablePython2.7.6.1\App\lib\lib-    tk\Tkinter.py", line 41, in <module>
TclError = Tkinter.TclError
AttributeError: 'module' object has no attribute 'TclError'

add a link to what is in `"C:\Heights\PortableApps\PortablePython2.7.6.1\App\lib\lib- tk\Tkinter.py`, it looks wrong to me — Padraic Cunningham, Aug 28 '15 at 19:27
@PadraicCunningham this is the link = http://pastebin.com/7dzNY2U1 — ErezProductions, Aug 28 '15 at 19:54
Try using this file http://pastebin.com/dFiCXv4W, make a copy of the original and replace with that — Padraic Cunningham, Aug 28 '15 at 20:04
@PadraicCunningham I did that, but now I got another traceback - (look up I changed the error given in the question) — ErezProductions, Aug 28 '15 at 20:15
@PadraicCunningham In pyCharm , I click "run" and select the wanted file — ErezProductions, Aug 28 '15 at 20:16
@PadraicCunningham So what can I do? Is there no way now I can create GUI? — ErezProductions, Aug 28 '15 at 20:19
What caused the new error, just importing or a line later in your code? Does adding `Tk()` after your from `Tkinter import *` fix the new error? — Padraic Cunningham, Aug 28 '15 at 20:20
I don't know what caused it. I just copied from the link you sent me, and then the traceback has changed. The code is still the same. — ErezProductions, Aug 28 '15 at 20:23
What happens if you simple run `from Tkinter import *` using the file I provided in place of the original? Also as previously asked does adding `Tk()` right after the import fix the new error? — Padraic Cunningham, Aug 28 '15 at 20:24
And using the original file just importing caused an error yes? — Padraic Cunningham, Aug 28 '15 at 20:26
does adding `from Tkinter import *;Tk()` fix the new error? Add a link to your actual code also — Padraic Cunningham, Aug 28 '15 at 20:28
I reverted your edit as it is what the real issue is, the problem is with portable python — Padraic Cunningham, Aug 28 '15 at 20:31
@PadraicCunningham http://pastebin.com/n2knv4jS this is the whole code. Now I have another problem instead - I changed it up in the traceback in the question above. — ErezProductions, Aug 28 '15 at 20:37
Add any errors to pastebin, leave the question as it was because these errors are from something unrelated, the fix has worked, the error is not related to your original question — Padraic Cunningham, Aug 28 '15 at 20:39
Your problem is you are passing an empty string so an empty string cannot be cast to a float — Padraic Cunningham, Aug 28 '15 at 20:42

@PadraicCunningham Why an empty string? I get data from the entry. — ErezProductions, Aug 28 '15 at 21:25

You imported (mostly) everything from the module with from Tkinter import *. That means that (mostly) everything in that module is now included in the global namespace, and you no longer have to include the module name when you refer to things from it. Thus, refer to Tkinter's TclError object as simply TclError instead of Tkinter.TclError.

I know that, however, I do not mention it even once in my code.. I just created some GUI's and I get this error – ErezProductions Aug 28 '15 at 18:46
Maybe you should include the full traceback in your question. – TigerhawkT3 Aug 28 '15 at 18:47
I did. you can tae a look – ErezProductions Aug 28 '15 at 19:36

The problem seems to be in "C:\Heights\PortableApps\PortablePython2.7.6.1\App\lib\lib-tk\Tkinter.py:

The regular python install imports in lib-tk\Tkinter.py are different to what is in PortablePython2.7.6.1\App\lib\lib-tk\Tkinter.py:

try:
    import _tkinter
except ImportError, msg:
    raise ImportError, str(msg) + ', please install the python-tk package'
tkinter = _tkinter # b/w compat for export
TclError = _tkinter.TclError

Then where Tkinter is used in PortablePython _tkinter is used instead. It seems like a bug in PortablePython.

The full contents of the file are here. Replacing the file in C:\Heights\PortableApps\PortablePython2.7.6.1\App\lib\lib-tk\Tkinter.py as per the comments fixes the issue.

Like @ErezProductions said. You either have to import everything and access it directly or import only the module.

from Tkinter import *
TclError

or

import Tkinter
Tkinter.TclError

See the difference:

>>> import tkinter
>>> TclError = tkinter.TclError
>>>

No error. But, with your method:

>>> from tkinter import *
>>> TclError = tkinter.TclError
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'tkinter' is not defined

The difference is that the first method imports the module tkinter into the name space. You can address its properties using the dot notation tinter.property. However, the from tkinter import * imports the module's properties into the name space, not the module itself.

Either try the first method given above, or adjust your approach (NB: importing all properties is a bad idea) like so:

>>> from tkinter import *
>>> my_TclError = TclError   # renamed because TclError defined in tkinter
>>>

Nope, I still get the traceback I gave in the question(look again I added more details) — ErezProductions, Aug 28 '15 at 19:23
