Welcome to the TEALS Intro to Computer Science Second Semester Python Curriculum. Its intended use was for classrooms that had already completed the content from the 1st semester course.
For schools in BC, Canada, please see Aligning TEALS Python Teaching Resources with the BC Curriculum.
We have included with this curriculum Associated Readings to dive deeper into topics specific to the instruction of this course. These readings have been adapted from "Think Python: How to Think Like a Computer Scientist" by. Allen B. Downey. (HTML Version)(PDF Version).They are specifically referenced in the lesson plans and the full document is included.
Python is an evolving language. Python 3 is a major upgrade to the language, released in 2010. There is a lot of existing software written under Python 2 and there is resistance to upgrading to Python 3 due to code breakage and cost. Just as a car part from a 10 year old model car will probably not fit a new model of the same car, Python 2 code probably would not run in a Python 3 environment. In Python 3 there are new features, significant upgrades "underneath" which makes the code run better and/or faster as well as no longer supporting (deprecating) some Python 2 capabilities. When looking at Python code, be careful to note whether it is Python 2 or Python 3.
For those knowledgeable with Python 2, the following is a list of differences from Python 3 relevant to the 2nd semester intro course.
| Python 2 | Python 3 | |
|---|---|---|
| Printing to console | print 3.14 | print (3.14) |
| User input | raw_input()/input() | input () |
| Integer arithmetic | 3/2 evaluates to 1 | 3/2 evaluates to 1.5 |
