Hello,
For example I have a string : "Halo by by by"
Then I want to take and know the possition of every "by"
how can I do it in python?
I tried to use:
p = re.compile(r"by ")
m = p.search("Helo by by by")
print m.group() # result "by"
print m.span() # result (5,7)
How can I get the information of the other by ?
Sincerely Yours,

You need re.findall() (or, equivalently, the findall() method of an re).

Hello,
I have a text file that I load up to a string. The text includes
certain expression like {firstName} or {userName} that I want to match
and then replace with a new expression. However, I want to use the
text included within the brackets to do a lookup so that I can replace
the expression with the new text.

Hi,
reg expressions are very handy but it's not my speciality. Can someone help
me constructing one for the next problem?
PxxyyPxxyyPxxyyy
Thats the string I have to split. The Pxx is always constructed like that, a
'P' and 2 numbers or letters.
The yy can be 1 or more numbers or letters.
The xx's and yy's belong to a group combined with the 'P' and I need both of
the values.
I guess I have to loop through a matchCollection.

Hi,
I am replaceing a big string using different regular expressions (see
some example at the end of the message). The problem is whenever I
apply a "replace" it makes a new copy of string and I want to avoid
that. My question here is if there is a way to pass either a memory
stream or array of "find", "replace" expressions or any other way to
avoid multiple copies of a string.
Any help will be highly appreciated

Hi,
i'm using the regular expression \b\w to find the beginning of a word,
in my C# application. If the word is 'public', for example, it works.
However, if the word is '<public', it does not work: it seems that <
is not a valid character, so the beginning of the word starts at
theletter 'p' instead of '<'.
Because I'm not an expert in regular expressions, maybe someone of you
guys can help me? I need the correct regex to find the...

I have a regular expression (^(.+)(?=\s*).*\1 ) that results in
matches. I would like to get what the actual regular expression is.
In other words, when I apply ^(.+)(?=\s*).*\1 to " HEART (CONDUCTION
DEFECT) 37.33/2 HEART (CONDUCTION DEFECT) WITH
CATHETER 37.34/2 " the expression is "HEART (CONDUCTION DEFECT)". How
do I gain access to the expression (not the matches) at runtime?
Thanks,

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
