+## Python in the Cloud
+
+The easiest way to get started coding in Python is by running it in the cloud.
+
+(That is, by using a remote server that already has Python installed.)
+
+There are many options for doing this, both free and paid.
+
+At present [Google Colab](https://colab.research.google.com/) seems to be the
+most reliable.
+
+Colab offers a free tier and also has the advantage of providing GPUs.
+
+The free-tier GPUs are adequate and better ones can be accessed by signing up
+for Colab Pro.
+
+Tutorials on how to get started with Google Colab can be found by searching.
+
+Written examples include
+
+* [Google Colab Tutorial for Beginners](https://pub.towardsai.net/google-colab-tutorial-for-beginners-834595494d44)
+* [Intro to Google
+  Colab](https://levelup.gitconnected.com/google-colab-what-is-it-how-to-use-it-and-why-should-i-care-721bb8a88c90)
+
+Videos on the same topic can be found by searching on Youtube.
+
+Most of our lectures include a "Launch notebook" (play icon) button on the top
+right that allows you to easily run them in Colab.
+
+
+## Local Install
+
+Local installs are preferable if you have access to a suitable machine and
+plan to do a substantial amount of Python programming.
+
+At the same time, local installs require more work than a cloud option like Colab.
+
+The rest of this lecture runs you through the details.
