+# Collections module
+
+## Day 1: Your new data structure friends
+
+Welcome to this lesson. Today you will learn about some powerful new data structures: `namedtuple`, `defaultdict`, `Counter` and `deque`.
+
+Today you watch the videos. I also prepared a [Jupyter notebook](https://github.com/talkpython/100daysofcode-with-python-course/blob/master/days/04-06-collections/collections.ipynb) so you can follow along with this lesson.
+
+## Day 2: Practice using movie data
+
+You get to use these new data structures I encourage you to code an exercise: [PyBites Code Challenge 13 - Highest Rated Movie Director](https://pybit.es/codechallenge13.html). 
+
+See the [notebook](https://github.com/talkpython/100daysofcode-with-python-course/blob/master/days/04-06-collections/collections.ipynb) for more info how to complete this exercise.
+
+You can also take a slimmed down version of this exercise [on our platform](https://codechalleng.es/bites/30/).
+
+## Day 3: More practice on your own data
+
+We challenge you to find your own data set and try to use the new collections data structures yourself.
+
+Stuck at finding examples? We used `collections` quite a bit for [when we did the 100 Days of Code](https://github.com/pybites/100DaysOfCode/blob/master/LOG.md):

+# List comprehensions and generators
+
+## Day 1: Ready to learn some powerful, Pythonic concepts?
+
+> List comprehensions and generators are in my top 5 favorite Python features leading to clean, robust and Pythonic code.
+
+Welcome to this lesson. In today's videos you will learn two powerful techniques you can use in Python: list comprehensions and generators.
+
+I prepared a [Jupyter notebook](https://github.com/talkpython/100daysofcode-with-python-course/blob/master/days/16-18-listcomprehensions-generators/list-comprehensions-generators.ipynb) so you can follow along with this lesson.
+
+## Day 2: Practice!
+
+Look at your code and see if you can refactor it to use list comprehensions. Same for generators. Are you building up a list somewhere where you could potentially use a generator?
+
+[My notebook](https://github.com/talkpython/100daysofcode-with-python-course/blob/master/days/16-18-listcomprehensions-generators/list-comprehensions-generators.ipynb) has an exercise to sink your teeth in. Please try it and tomorrow I will discuss the solution.
+
+## Day 3: Solution / simulate unix pipelines
+
+I will detail the solution of yesterday's exercise [in my notebook](https://github.com/talkpython/100daysofcode-with-python-course/blob/master/days/16-18-listcomprehensions-generators/list-comprehensions-generators.ipynb)
+
+Today if you have time left, I encourage you to try 2 extra exercises [on our platform](https://codechalleng.es):
+- [Bite 5. Parse a list of names](https://codechalleng.es/bites/5/) (use a set comprehension in first function)
+- [Bite 26. Dictionary comprehensions are awesome](https://codechalleng.es/bites/promo/awesome-dict-comprehensions)
+
+If you still have time left, or you prefer to practice generators check out this cool blog code challenge: [Code Challenge 11 - Generators for Fun and Profit](https://codechalleng.es/challenges/11/)

+# Decorators
+
+## Day 1: Quick howto
+
+Welcome to this lesson. Decorators are a sometimes overlooked and more advanced feature. They support a nice way to abstract your code. Although hard to grasp at first there is not that much to it. 
+
+In today's videos you will watch me explain this powerful concept. You can follow along with my Jupyter notebook [here](https://github.com/talkpython/100daysofcode-with-python-course/blob/master/days/22-24-decorators/decorators.ipynb).
+
+## Day 2: A practical exercise
+
+Try to take a crack at [Bite 22. Write a decorator with argument](https://codechalleng.es/bites/promo/decorator-fun).
+
+If you get stuck we have a more open-ended challenge as well: [Write DRY Code With Decorators blog challenge](https://codechalleng.es/challenges/14/).
+
+Look at the code you have written so far, where could you refactor / add decorators? The more you practice the sooner you grok them and the easier they become.
+
+## Day 3: More practice
+
+The exercise and code challenge of yesterday should keep you busy for a bit, today get some more practice in. 
+
+## Time to share what you've accomplished!
