[Sugar-devel] GSoC Project Update - 27th July 2020

[Saumya Mishra]

Hello all,
I am sharing the progress I made in my project -  *Port Sugar and core
activities to Python3* after 1st evaluation.

*Sugar: *

   - The two tracebacks present in sugar while adding a friend and deleting
   a friend in Group View has solved. Thanks to @James Cameron
   <quozl at laptop.org> for helping me out. See #921
   <https://github.com/sugarlabs/sugar/pull/921>
   - Remove use of Webkit1 by James

*Sugar-toolkit-gtk3:* Changes in #451
<https://github.com/sugarlabs/sugar-toolkit-gtk3/pull/451>

   - Port to Python3 - remove the use of WebKit1 ( WebKit1 API is not
   available for Python 3)
   - Port to Python3 - get_preview returns bytes ( Change made in the doc)
   - Change type of units for zoom ( As zoom accepts float as well as int
   units)

*Write:*

   - Pasting images (eg. the ones copied from the web ) using CTRL+V throws
   errors

Traceback (most recent call last):
>  File "/usr/src/sugar-activities/Write.activity/toolbar.py",
>  line 160, in __paste_button_cb px_file.write(data)
> TypeError: write() argument must be str, not bytes

   -  Remove unnecessary errors printed in logs.

Change from logging.error to debug.
