Hi,

Yes, someone else also suggested a dictionary, and I agree it is the
best way to go. Potential name clashes had not occurred to me till you
mentioned it, though.

I'm trying to produce a list of DNA sequences for further manipulation
with the names and the values of the sequences read from a file into
strings, and so in this case, the value of foo would be the name of
the sequence, and the value of bar would be the value of the sequence.

However, I'll look at what other people have suggested. I am new to
python and so don't even understand the answers, but will read up on
exec etc.

I own one of your books, by the way (Accelerated C++). :-)

Thanks to everyone who replied.
