Comment(by eviatarbach):
Append is marginally faster (by about one microsecond), probably because
for the other I had to declare a global ''index'' variable in Python.
Let me get this straight:
== Python ==
Filename: debruijn_sequence.py
Class name: DeBruijnSequence (DeBruijnSequences wouldn't make sense since
only one is generated)
== Cython ==
Filename: debruijn_sequence.pyx
Function name: debruijn_sequence
Is this correct?
Also, for some reason, when I use underscores in debruijn_sequence.py, I
get this error:
{{{
ImportError: dynamic module does not define init function
(initdebruijn_sequence)
}}}
Thank you!
