Tkinter File Pattern Set In A File Dialog
To get the set of expected files with given extensions in a file dialog, I've seen in several places written patterns as ('label','pattern'), the pattern being in one string. Howev
Solution 1:
If you are trying to associate two or more suffixes with a single file type (eg: "image files"), there are a couple of ways to do it.
declare each suffix separately
You can specify each suffix on a separate line. They will be combined into one item in the dropdown list:
filenames = fd.askopenfilenames(
title="Choose a file",
filetypes=[('all files', '.*'),
('text files', '.txt'),
('image files', '.png'),
('image files', '.jpg'),
])
using a tuple
You can also specify them as a tuple:
filenames = fd.askopenfilenames(
title="Choose a file",
filetypes=[('all files', '.*'),
('text files', '.txt'),
('image files', ('.png', '.jpg')),
])
Solution 2:
Use tuple ('.png', '.jpg')
('image files', ('.png', '.jpg')),
Solution 3:
importtkinteroptions= {}
options['defaultextension'] = '.txt'
options['filetypes'] = [('all files', '.*'), ('text files', '.txt'),('asc files', '.asc')]
options['initialdir'] = '.'
file_open = tkinter.filedialog.askopenfile(mode='r', **options)
