Well, the OP said the function was returning None which meant
no match which implies None means composite for the given example 2.

If None was supposed to mean prime, then why would returing None
for 2 be a  problem?

But isn't this kind of silly?

##    3 None
##    4 <_sre.SRE_Match object at 0x011761A0>
##    5 None
##    6 <_sre.SRE_Match object at 0x011761A0>
##    7 None
##    8 <_sre.SRE_Match object at 0x011761A0>
##    9 <_sre.SRE_Match object at 0x011761A0>
##    10 <_sre.SRE_Match object at 0x011761A0>
##    11 None
##    12 <_sre.SRE_Match object at 0x011761A0>
##    13 None
##    14 <_sre.SRE_Match object at 0x011761A0>
##    15 <_sre.SRE_Match object at 0x011761A0>
##    16 <_sre.SRE_Match object at 0x011761A0>
##    17 None
##    18 <_sre.SRE_Match object at 0x011761A0>
##    19 None
