python - Restricting the file extension saved when using tkFileDialog.asksaveasfile -


i writing gui in python using tkinter user able save state of gui in directory extension ".espace".

filename = tkfiledialog.asksaveasfilename(defaultextension=".espace")

if user specifies different file extension file saved extension specified. there anyway prevent this? restricted saving file extension ".espace"?

thanks in advance.

you can specify file type using 'filetypes' option. below example change file type drop down on save dialog .espace , files.

filename = tkfiledialog.asksaveasfilename(defaultextension=".espace", filetypes=(("espace file", "*.espace"),("all files", "*.*") ))

i have not found option, using asksaveasfilename, restrict use of other file extensions. i'd think write loop force user use extension:

import os import sys ext = "" while ext != ".escape":    filename = tkfiledialog.asksaveasfilename(defaultextension=".espace", filetypes=(("espace file", "*.espace"),("all files", "*.*") ))    file,ext = os.path.splitext(filename)

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
