Suppose I want a regular expression that matches both "Sent from my iPhone" and "Sent from my iPod". How do I write such an expression?
I tried things like:
re.compile("Sent from my [iPhone]|[iPod]")
but doesn't seem to work.

@lapinkoira My answer wouldn't match the stringsiPhoneoriPodon there own. It will only matchSent from my iPhoneorSent from my iPod, just like the OP wants. There is a difference between what is matched and what is captured, and the OP only asked about what is matched.re.compile("(iPhone|iPod)")would find a match in the stringRed iPhone, but my answer doesn't, since my answer requires the string to haveSent from mybefore eitheriPhoneoriPod. Btw, regular expressions don't output anything, so I'm not sure what you mean by that.

The other answer just suppresses capturing the group, so while both of our answers givematch.group(0) == 'Sent from my iPhone', mine also allows you to get just the part that was captured separately if you want usingmatch.group(1) == 'iPhone', whereasmatch.group(1)in the other answer would throw anIndexError: no such group.

re.compile("Sent from my (?:iPhone|iPod)")
If you need to capture matches, remove the ?:.
Fyi, your regex didn't work because you are testing for one character out of i,P,h,o,n,e or one character out of i,P,o,d..

No they are testing for "Sent from my " and then one of the characters i, P, h, o, n, or e; OR one of the characters i, P, o, or d. The vertical bar for OR is topmost scope, and the left hand side has "Sent from my" in it but the right hand side does not.
