Tkinter File Handling: asksaveasfilename()
Introduction
This tutorial explores the various aspects of the
asksaveasfilename() function in Tkinter, a library for creating user interfaces in Python.
File Types Option
The
filetypes option allows you to specify the types of files that can be saved. The format is a list of tuples where each tuple contains a description and a sequence of file extensions. For example:
filetypes = [("Text Files", "*.txt"), ("Python Files", "*.py")] Default Extension
The
defaultextension option specifies the default file extension for the saved file. If no extension is specified, the file will be saved without an extension.
File Save Dialog
The
asksaveasfilename() function creates a file save dialog that allows the user to choose a file path and name. The returned value is the path to the selected file or an empty string if the user canceled the dialog.
filename = tkinter.filedialog.asksaveasfilename(filetypes=filetypes, defaultextension=".txt") Examples
Here are some examples of using the
asksaveasfilename() function:
# Save a text file filename = tkinter.filedialog.asksaveasfilename(filetypes=[("Text Files", "*.txt")]) # Save a Python file filename = tkinter.filedialog.asksaveasfilename(filetypes=[("Python Files", "*.py")], defaultextension=".py") # Save a file with a custom extension filename = tkinter.filedialog.asksaveasfilename(filetypes=[("All Files", "*")], defaultextension=".custom")
