Executing Python Code
Instructor Note
For this lesson, it would be a good idea to poll the learners about what operating system, shell, and text editor they are using.
Helpers should keep an eye on the learners to make sure they are able to open a terminal, start a Python REPL session, and open a text editor.
Types and Operators
Instructor Note
Floats are so called because they represent numbers that can “float” around the decimal point.
Instructor Note
Not all programming languages have the same rules and conventions for variable names.
For example, in R, variable names can contain dots (.)
and dashes (-), but in Python, these characters are not
allowed in variable names. In JavaScript, variable names can contain
dollar signs ($), but in Python, this character is not
allowed in variable names. In PowerShell, variable names are not
case-sensitive, but in Python, variable names are case-sensitive.
