[python-win32] Tkinter newbie

[Andreas Holtz]

Hi John,

seems you lack basic understanding of Python (and perhaps programming languages at all?).
I recommend you reading a book like
"Learning Python" from Mark Lutz or check some courses on
https://wiki.python.org/moin/BeginnersGuide/Programmers

Then you will learn the differences between attributes/variables (no "()") and functions (with () )
and methods (self.x() and x(self)).

Later you will ask Google "tkinter open file" and get as first result
http://tkinter.unpythonic.net/wiki/tkFileDialog

You will look at the example and understand that line 45 fullfill your needs:
tkFileDialog.askopenfile(mode='r', **self.file_opt)

But you'll ask yourself, where does **self.file_opt come from and you'll understand that line 20
is the interesting thing.

Eventually you'll understand, that
options = {}
options['defaultextension'] = '.txt'
options['filetypes'] = [('all files', '.*'), ('text files', '.txt')]
options['initialdir'] = 'C:\\'
options['initialfile'] = 'myfile.txt'
options['parent'] = root
options['title'] = 'This is a title'
selectedFile = tkFileDialog.askopenfile(mode='r', **options)

is the code you are looking for.

And perhaps you'll ask yourself, why you wanted to waste the precious time of others at the
beginning, when learning and exploring by yourself makes so much more fun.

Best Regards

Andreas
