Last night I took the advice of a DaniWeb member and looked at some posted Python code; this code was based around a card-type game and involved creating a GIF deck, shuffling, then displaying it. My original question had to do with using a Python dict for my GIF images.

I downloaded the code and attempted to run it. The problem I keep getting, I'm sure, is not of a Python nature, but a programming problem in general.

Each time I run the code I get this:

C:/Python24/pythonw.exe -u  "C:/Documents and Settings/RockStar/Desktop/Python/drpython-161/LLCool_J.py"
Traceback (most recent call last):
  File "C:/Documents and Settings/RockStar/Desktop/Python/drpython-161/LLCool_J.py", line 61, in ?
    photo1 = PhotoImage(file=image_dir+"C2.gif") 
  File "C:\Python24\lib\lib-tk\Tkinter.py", line 3203, in __init__
    Image.__init__(self, 'photo', name, cnf, master, **kw)
  File "C:\Python24\lib\lib-tk\Tkinter.py", line 3159, in __init__
    self.tk.call(('image', 'create', imgtype, name,) + options)
_tkinter.TclError: couldn't open "C:\Documents and Settings\RockStar\Desktop\Python\drpython-161\Cards_gifC2.gif": no such file or directory

I have these GIF images in the folder with my other Python files; the I tried putting them in a seperate file within this same Python folder. I change the code on every folder file change. I simply keep getting this error.

Has anyone dealt with this particular problem. It seems that it would be easy to solve but I am not finding the right solution.

** Also, does anyone know of a relevant Python error code source (similar to MSDN) that would describe in-depth what the thrown error means and the potential fixes.

Thank-you in advance,

C:\Documents and Settings\RockStar\Desktop\Python\drpython-161\Cards_gifC2.gif looks like your image directory is C:\Documents and Settings\RockStar\Desktop\Python\drpython-161\ and your image file name is Cards_gifC2.gif . You wnat to make this C:\Documents and Settings\RockStar\Desktop\Python\drpython-161\Cards_gif\ and then the image name will be C2.gif

Thank-you for your reply.

I followed your advice but I get another error, a result I do not understand; upon Run, it appears that the code appends "C2.gif" to this file location, resulting in: "C2.gifC2.gif" I do not understand why the code below is written this way or what the purpose is when accessing a folder file.

Your error is in the line:

image_dir = "C:\Documents and Settings\RockStar\Desktop\Python\drpython-161\Cards_gif\C2.gif"

you have to change it to just the directory name:

image_dir = "C:\Documents and Settings\RockStar\Desktop\Python\drpython-161\Cards_gif\"

you have to change it to just the directory name:

image_dir = "C:\Documents and Settings\RockStar\Desktop\Python\drpython-161\Cards_gif\"

I tried the above code but it returned an error: EOL

I fixed this by appending an additional "\" to this line:

image_dir = "C:\Documents and Settings\RockStar\Desktop\Python\drpython-161\Cards_gif\[B]\[/B]"

This worked and the program runs.

It is strange, though; I do not recall seeing this before or ever using the additional "\" in Python in order to access files in a folder.

Thanks again for your help. ;)

It depends what character follows the '\', if its 'n' then it becoames an escaped character like '\n' and will behave like a newline. I forgot to add the r in front to avoid this behaviour, like:

image_dir = r"C:\Documents and Settings\RockStar\Desktop\Python\drpython-161\Cards_gif\"

or you can do this:

image_dir = "C:\\Documents and Settings\\RockStar\\Desktop\\Python\\drpython-161\\Cards_gif\\"

That's the way it's done in C/C++ code.
