from c++ to pyqt4 QByteArray

[amleto]

sigh. Next time please be more wary of wasting people's time with nonsense code. Also use code tags!
I still don't understand what this is meant to be doing

char nucl = seq[i];
char complNucl = map.at(nucl); // map.at takes an int - why is a char being passed here?  You get trouble if char is signed and a negative number...

char nucl = seq[i];
char complNucl = map.at(nucl); // map.at takes an int - why is a char being passed here?  You get trouble if char is signed and a negative number...
