Hi, I want to open a file and after a simple processing, save the
result in a file with the same name but with different extension. For
example, open a file name "test.bmp" and save the result in
"test.txt". I used the GetPath method of wx.FileDialog, but I know the
resultant string contains the extension of the opened file, "bmp" in
my example. So I use GetPath().[:-3]+"txt" to get the output
name automatically. I know it is quite stupid, and there must be a
built-in, smarter way to make it. In this case, I know the input file
extension is three letters long, but if the file is someting like
"test.tiff", then this method gives a wrong result.
Any help is appreciated.
This one works too:
newname = os.path.splitext(filename)[0] + ".txt"

filename = 'foo.bar'
newname = filename.rsplit('.', 1)[0] + '.txt'
Oh, that works, thanks a lot, Andrea.
By the way, from the link in your signature, I found you are the “Infinity 77” owner. Oh my god, when I just started learning python and pywxPython one month ago, I already found your webiste is really really helpful. A bunch of amazing gadgets are written by you. Thanks for your work to the python community.
