Other Digital Version Appendix c
Step12

I am having difficulty getting past step 12 of the procedure in Appendix C. After the file is unzipped, I get a series of questions which starts with "replace Adafruit-Raspberry-Pi-Python-Code-master/Adafruit-ADS1x15/Adafruit_ADS1x15.py? I don't know how to answer these questions. No matter what I answer, I get the message that ads1015_example.py does not exist. Would you please put me on the right bus to get my RaPi and ADS1015 working. Thanks very much.

"Don't update the OS on your first time around: you'll see other ways to do this in Chapter 2."
You cover apt-get on pg. 32 but don't really discuss the updating of the firmware/os itself.

If you want to watch recorded TV and DVDs encoded in the MPEG-2 format (or Microsoft’s VC-1 format), you’ll need to purchase >>>an<<< license key from the
Foundation’s online shop.

2nd bullet point in sole list

Text reads:

Use _print()+ to show the values of variables as the program executes.

I'm guessing this should also be, a simple "print()". Perhaps the "_print()+" was meant to markup the text in order to produce bold text?

If there is a deeper meaning here, then it should be made more explicit in a footnote.

bulleted list, line 2

it says to help troubleshoot, to use the language construct

_print()+

however, I find NO REFERENCE to this construct anywhere in the book, nor do I find this item at 'python.org' - what I 'thought' was the 'definitive' source on all things having to do with Python?

Might there be an explanation and/or example somewhere?

3rd paragraph

1.A resistor of about 220 ohms must be used in series with an LED to prevent excess current flow. Current should be limited to about 5 milliamps for a GPIO pin.

2. On my LED the cathode had the longer lead.

top bash source

in the bash code-snippet at the top of page 96 there are 'trailing "#" characters on some of the lines that 'fail to compile' (or run)...

I removed these 'trailing "#"' to get the script to run

I do NOT FIND similar trailing "#" on a very similar script at the top of page 97

Harumph?
