My students are adult programmers, working in the Silicon Valley.
I have to try to make the class efficient, useful, and fun. Many
are sent to us by their employers.
So far, they seem very happy and engaged with the class. Let's hope
In all my jillion years of teaching C, I never had all the students
show up on time for the first class. But all 19 people made it to the
first python class on time. What does this mean?
A few were a little late to the second class but all were present.
After the first class, I start on time.

YES. I learned Perl because I wanted something new to teach and it
was so popular at the time. When I started learning the OO 'features'
I dropped it like a hot rock and decided I could never teach something
I disliked so much.
Someone suggested I look at python, and like everyone else, I flipped.

Great! I'll point my students to this.
What a huge help this list is! Something about this language is like
a generator of sense in a confused world. I'm almost a fanatic, and
I'm not the fanatical type.
