When I cloned the repository on my local system, I am not able to follow the logical order of the notebooks. In other words on the Github Repository a logical order is specified against each topic as below:

1. Strings [notebook] [exercise]
2. Numbers [notebook] [exercise]
3. Conditionals [notebook] [exercise]
4. Lists [notebook] [exercise]
5. Dictionaries [notebook] [exercise]
6. For loops [notebook] [exercise]
7. Functions [notebook] [exercise]
8. Testing with pytest - part 1 [notebook] [exercise]
9. Recap exercise 1 [exercise]
10. File I\O [notebook] [exercise]
11. Classes [notebook] [exercise]
12. Exceptions [notebook] [exercise]
13. Modules and packages [notebook]
14. Debugging [notebook] [exercise]
15. Goodies of the Standard Library - part 1 [notebook] [exercise]
16. Testing with pytest - part 2 [notebook] [exercise]
17. Virtual environment [notebook]
18. Project structure [notebook]
19. Recap exercise 2 [exercise]

But in the Cloned repository the files are in the albhatic order of the file name. There is no way to know in which order one should study. I think it will be better that we should put some index for these notebooks for easy navigation.

Also the same situation for HTML pages. There should be some logical order for those.

Thanks

virtualenv, pip, easy_install, ??? What is the idiomatic package manager development environment that is best from a enterprise developer perspective! I would contribute an answer if I knew it.

I suggest you add this popitem also in dictionaries

my_dict = dict(food='ham', drink='beer', sport='football')
print('dict before pops: {}'.format(my_dict))

result = my_dict.popitem()
print('Result: {}'.format(result))
print('dict after popping items: {}'.format(my_dict))

When doing the "testing with pytest part 1" notebook, there is an error, saying that a attribute called ipytest.magic doesnt exist. When having a look at the page for ipytest, i noticed that the usage seems to have changed. https://pypi.org/project/ipytest/
Did i understand that correctly? I installed ipytest for the first time today.
