re.sub and re.MULTILINE

[nyenyec]

I feel like a complete idiot but I can't figure out why re.sub won't
match multiline strings:

This works:

>>re.search("^foo", "\nfoo", re.MULTILINE)

<_sre.SRE_Match object at 0x6c448>

This doesn't. No replacement:

>>re.sub("^foo", "bar", "\nfoo", re.MULTILINE)

'\nfoo'

Why?

Thanks,
nyenyec

Check the arguments to re.sub.

>>re.sub('(?m)^foo', 'bar', '\nfoo', count=0)

'\nbar'
