[Tutor] Re: Convert list to literal string.

[Decibels]

I can make a loop and process the info. But you can pass Yahoo
an entire list of symbols and it will return the information.
I can make this work:

def addstock_info(addstock):
        stock = addstock
        scount = len(stock)  
        print "Getting Stockinfo data from Yahoo"
        for x in range(0,scount):
                results=quotes.findQuotes(stock[x])

With that I can pass from the command-line for example:

--addstocks  IBM,EK,MO,UTX

and loop thru them.  

I was just thinking that I could do it without looping,
since if you bypass the 'addstock' and do this:

def addstock_info(addstock):
        stock = "IBM,EK,MO,UTX'  #ignoring string passed from command-line
        print "Getting Stockinfo data from Yahoo"
        results=quotes.findQuotes(stock)

This will work also, but doesn't allow user input.

I have other functions doing stuff with command-line, but I am processing parts 
of the string. So accessing parts of it is fine.

Don't know, it might be just as fast? Was thinking it might be faster to get the quotes
from Yahoo in one swoop instead of looping.  So wanted to change to a literal string
if could figure out how. Maybe it should work, but when you send the symbols from
the command-line it doesn't unless I pass each one seperately. I must be doing something
wrong.
