Greetings,
I am using IPython 6.1.0 with Python 3.6.2 on a Windows 7 machine. I am
not a programmer. I am using a book called Python Data Analytics to try
to learn some of Python. I am at a section for reading and writing JSON
data. The example JSON file is:
Listing 5-13. books.json

Interesting problem, John.
I have probably even less experience with json than you do, so I'm
taking this as an opportunity to learn with you.
Suggestions:
1. Try your example with Python 2 rather than Python 3.
Bill,
Thanks for the reply. I wasn't sure how

It looks to me like the root cause of the problem was that they copied
the code from a web page, and the web page contained invalid JSON.
Thank you, Thomas.

I am trying to make practice data for plotting purposes. I am using

plt.plot(t,y1)

Greetings,
I am attempting to learn Python. I have no programming background. I'm
on a computer with Windows 7. I checked the PATH in System Variables and
Python and Python\Scripts are in the path. I have a book, Python for
Biologists and it supplies example scripts, one is called comment.py.

I had a misconception of how the Python interpreter works. If I have a
script, call it example.py, in order to run it, I shouldn't be in the
interpreter? In other words, I should be at the Windows command prompt,
for example

and not

I am using Python 3.6 on Windows 7.

Python People,
I am learning about assertions. I wrote a small script that takes 2
inputs, an amino acid sequence and one residue symbol. The script should
return what percent of the sequence is residue in output. The point of
this script is to use assert for debugging. My script seems to work
ChrisA,
Thank you for pointing out my error: using print() when I should have
used return().
