So here's a tentative contest version of the code:
import sys import string
def show(seq, table=string.maketrans('ACBDGHK\nMNSRUTWVYacbdghkmnsrutwvy', 'TGVHCDM\nKNSYAAWBRTGVHCDMKNSYAAWBR')): seq = seq.translate(table)[::-1] for i in range(0, len(seq), 60): print seq[i:i+60]
def main(): seq = [] for line in sys.stdin: if line[0] in ';>': show(''.join(seq)) print line, del seq[:] else: seq.append(line[:-1]) show(''.join(seq))
main()
Looks pretty good. (And yes, I definitely prefer the unaliased ''.join and seq.append for readability's sake. Glad to know they try to grade on that too.) =)
Only one other suggestion: "range" in the show function should probably be "xrange". "range" is going to create an actual list of however many integers, while "xrange" will just create the integers as needed. "xrange" thus will be more memory friendly. (It's also occasionally faster, though this depends a lot on the rest of the code).
