Congratulations! If you have reached this point, we are sure you are willing to keep learning while helping others.

For this winter campaign, Code For A Change team has decided to give you a gift. Either if you have already practised Python, you have some experience, or you want to start from scratch, it is always very difficult to remember all the key concepts of this programming language. Furthermore, we introduce you to the NumPy and Matplotlib world, which are “libraries” that help you work with your data and  visualise it by plotting the most beautiful graphs. For this reason, we are giving you three different summaries (or cheat sheets) containing these key concepts that you should remember as a Python programmer.

How can I download these cheat sheets?

Click on each of the options for more details:

  • Step 1: Make a donation to Change Lives to bring internet access to our selected students from IE San Jose, Circasia, Colombia. Add your name in the donation. 
  • Step 2: Send us a screenshot to under the concept “Cheat sheets password”. We will send you a password to download the cheat sheets.
  • Step 1: Follow @codeforachange on Instagram.
  • Step 2: Share our post and tag @codeforachange, encouraging people to donate and to follow us.
  • Step 3: Send us a DM, and we will send you a password to download the cheat sheets.


The Co-Founders would like to thank publicly Karl Hvarregaard Mose (Undergraduate, Computer Science at Cambrige University) for his voluntary help with the creation of the content of these cheat sheets.
