In the last months I have been reading a ton of articles here, even if I am not a "full" developer. Indeed I am a data scientist.
Now, since I would like to contribute in a more active way, I think that a nice way to start may be a post with some resources that used lately, during my data science activity.

Without further ado, here it's the list:

• If you are in the business of object detection but your pictures are not already labeled try LabelImg https://github.com/tzutalin/labelImg
• https://www.any-api.com provides documentation and test consoles for over 500 public APIs. Just to name a few: NBA,Spotify, Gmail.
• Tabular data are not always found in csv files. Sometimes you need to extract them from a pdf: check out camelot https://github.com/socialcopsdev/camelot
• Nice blog post to use pandas at its best https://realpython.com/fast-flexible-pandas/

I hope that this links can be useful for someone else.
I gladly appreciate any feedback.
