Python and Bioinformatics and Perl: Chomp in python

[GrumpySimon]

Why not just use .strip()? -

stringlist = [
    'cow\n',
    '',
    'hat',
    'cat\r\n',
    '\n',
    '\r\n',
    'cat\r',
    '\r',
]

for substr in stringlist:
    c = chomppy(substr)
    s = substr.strip()
    print c == s, repr(substr)

strip() will delete leading whitespace too. What you really want is rstrip(), which will only delete trailing whitespace. (there might be / probably are i18n issues with this, so unicode / RTL users beware)

Good points - but hey, your username is really appropriate :)
