The curriculum repo will remain available and anyone who wants to develop it further can fork it. ## A 2nd semester follow-up to the [TEALS Intro CS course](https://tealsk12.github.io/introduction-to-computer-science/) * GitHub: https://github.com/TEALSK12/2nd-semester-introduction-to-computer-science * Github Pages: https://tealsk12.github.io/2nd-semester-introduction-to-computer-science/ The following has been deprecated after the 2019/20 school year: * GitBook: https://tealsk12.gitbooks.io/2nd-semester-introduction-to-computer-science/content/ ## About this curriculum 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](https://tealsk12.github.io/introduction-to-computer-science/) prior to this curriculum. For schools in BC, Canada, please see [Aligning TEALS Python Teaching Resources with the BC Curriculum](CA_README.md.html). ## Associated readings 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](http://greenteapress.com/thinkpython/html/index.html))([PDF Version](http://www.greenteapress.com/thinkpython/thinkpython.pdf)).They are specifically referenced in the lesson plans and the [full document](readings.md.html) is included. ## Python Versions (2 vs 3) 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. ### This class uses 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 | ### IDE Selection As with all software services, it is the school's sole decision to use the tool according to the use terms and privacy policies provided by its licensor and it is the school's responsibility to ensure the tool meets it's IT policies. ## Curriculum issues and answer keys TEALS will no longer be making updates to TEALS curricula.
