Hi,
I'm trying to compile a regex Python with the re.VERBOSE flag (so that I can
add some friendly comments).
However, the issue is, I normally use constants to define re-usable bits of the
regex - however, these doesn't get interpreted inside the triple quotes.
For example:

It's essential to know about regex, of course, but often there's a better,

One of Python's aims is clarity and ease of reading.

I found another bug while looking through the source.
On line 495 in function SRE_COUNT:
if (maxcount end - ptr maxcount != 65535)
end = ptr + maxcount*state-charsize;
where 'end' and 'ptr' are of type 'char*'. That means that 'end - ptr' is

In function SRE_MATCH, the code for SRE_OP_GROUPREF (line 1290) contains this:
while (p e) {
if (ctx-ptr = end ||
SRE_CHARGET(state, ctx-ptr, 0) != SRE_CHARGET(state, p, 0))
RETURN_FAILURE;
p += state-charsize;

Look through some code I found this and wondered about what it does:
^(?Psalsipuedes[0-9A-Za-z-_.//]+)$

1) ^ match at start of string
2) ?Psalsipuedes if a match is found it will be accessible in a variable
salsipuedes
3)
901 - 1000 of 2838 matches
