This is why, by default, GitHub should have notifications set to off unless the user subscribes to updates: getting spammed emails at 5AM eastern on a Sunday just because I have access to the repository. Also, the emails github sends makes the user log into the site to update notifications rather than have a hyperlink in the email that redirects directly to the unsubscribe action. Such a joy to be dealing with these things before the sun comes up on a Sunday. Onward. https://help.github.com/en/articles/subscribing-to-and-unsubscribing-from-notifications ^ If you are tired of these spam emails. On a positive note: fantastic course professor. Keep the content coming. My only gripe is these notifications which I just remedied following the link above. |

taking the course in Udemy - Complete Python Bootcamp: Go from zero to hero in Python 3 ([email protected])
first review, I found dificulties in how to find a square root of a number, reassign values in lists, Dictionaries and Sets.
this is my first review.
I'll check my faults and review lists, dictionaries ans Sets to complete my datastructure_assesment
I would love some feedback if it's possible.
thank you so much

... I've just realized that this is not mine... lol sorry bro. I'm new... I was exited with the asignment and I've open this file and writed.. if you're new also, at the moment, i use visual studio code and download the plug ins to python. you can test the output also... hope it helps. maybe we can help eachother in the future ;)
