Packaging With PyInstaller

Here are resources and additional documentation about PyInstaller:

00:00 Packaging Your PySimpleGUI Application for Windows. There are many different Python packages that you can use to convert your Python code into an executable for Windows.

00:12 One of the most popular is PyInstaller. As ever, you can install PyInstaller using pip.

00:32 Here, you’ll use PyInstaller to convert the image viewer application that you created earlier into an executable. You can see the command onscreen, and when you run this, you’ll see a lot of output similar to the following.

00:47 When it’s done, you’ll have a subfolder named dist/ in the same folder that contains img_viewer.py. You can go into the dist/ folder to find img_viewer.exe and try running it.

01:11 There will be a lot of other files in the dist/ folder that the executable uses. If you prefer to have only a single executable file, then you can rerun the command using the --onefile flag as seen here onscreen.

01:24 This will still generate the dist/ folder, but this time there should be just a single executable in it. Note that Windows Defender may flag your executable as having a virus if you use the --onefile flag. If it does, then you’ll need to add an exclusion to Windows Security to get it to run.

01:44 This is because Windows executables need to be signed in Windows 10. When you run the executable, you’ll see a console window appear in addition to your user interface. To remove the console, you can use the --noconsole or the --windowed flag when running PyInstaller.
