Initially I got my quotes from a broker daily to plug into a
spreadsheet, Then I found Yahoo and wrote a perl script to grab them.
When Yahoo quit supplying quotes I found AlphaVantage.co and rewrote
the perl script.
AlphaVantage.co has been down since last week and I found

For Friedrich's, Peter's and the many other responses, many thanks.
I will get a handle on python eventually and the many teachers on this

Let's say I want something that does most or all of foo's
functionality plus a little more and maybe tweek some of foo's
output, so I write a wrapper around foo and call it bar.
If inside bar are the call to foo, as well as methods baz(),
buz() and bug() that make their magic and bar ends up pe

In their discussion of 'List replication operator'
Steven D'Aprano and Ben Finney used these '_' and '__'.
Steve said, "[[] for _ in range(5)]".
Ben said, "[ [] for __ in range(5) ]".
These aren't listed separately in the index, where might I find
written discussion of these?
Thanks,
Mike
To the many who responded, many thanks.
I,too, found Nick Coghlan's answer iluminating.

I'm having understanding the use if the ellipsis.
I keep reading that it is used in slices but every time I use it I get
'Syntax error' in 2.7 if 'Type error' in 3.2.
In python2.7:
l=range(15)
l[...:11]
Syntax error
l[3:...]
Syntax error
l[3:...:11]
Syntax error
In python3.2 it becomes 'Type
OK so I installed python 3.2, which is the latest available as a
package in Debian Wheezy, because I've seen so many folks say it's a
waste of time to play with Py2.7.
Immediately my python playground 'my.python.py' failed as soon as
I changes the '#!' line to python3.2.
