This is only applicable to the interpreter, though. It's perfectly legal to

Nice mention of the struct module, Alan. I had forgotten about it and

Seems like when they press "op" you assume that the current number is
done being executed and save the value. Then when they press another
op, you evaluate the previous op with the new value. You don't update
the display until they start typing again.
However, when they press =, you evaluate the

It probably won't be fast enough. I wrote an NES emu in python and I ran into a

If you're new to emu scene, start with David winters' doc and write a chip-8

Instead of nested fors which will grow exponentially in running time, consider

Next time you email tutor, start a new email msg instead of clearing out the
contents of a reply to a different e-mail. When you do it like that it breaks

I confess I don't know a lot about C so I may be off base here... But it looks
like your c func extendarray returns a pointer to the new extended array, but
you are not capturing this pointer in your python when you call the c func. So
the python code is pointing at the old deallocated array.
If you can assume a well formatted file I would just parse it linearly, should
be much faster. Read the file in as lines if the XML is already in human
readable form, or just read in blocks and append to a list and do a join() when

Read() does return a string. I guess the better question would be... Are you
using read? 'cause in the example you sent you used readlines() which returns a

Not really a python question, but maybe look at that pyexcel or whatever.
Should be able to add links to it that way. Csv is jus a data interchange

otherwise don't use csv for this.

It's saying one of your variables is not a string. Is one of them a sequence?
Perhaps Mir-seq? If so, you need to come up with a way to build a string from
this object. You can call the str method and pass in your object or you can
explicitly create a string from the data in the object.

effort you could make would be to find the relevant Python 3 document
