@shinya.ta As I said previously, you have to swipe 3 fingers up to close the keyboard.
And after, the x button is available to close the script.

But, first, use of 3 fingers needs you disable Settings/General/Accessibilty/Zoom.

Edit: if you prefer another gesture, let me know, but this is the standard IOS Braille gesture to simulate a return key, thus dismiss the keyboard.

As the owner of GrabzIt I would like to recommend you check us out we provide a highly flexible HTML to PDF API. The linked example has a Python demo for your convenience.

I have had the same problem multiple times. It must be related to some meta data of the file - when I copy the code into a new file, this new file works fine, also with the same name.

@cook Cool, tomorrow!
