Replace \0 by \g<0> in python sub
> The back reference \g<0> substitutes in the entire substring > matched by the RE. > http://docs.python.org/2/library/re.html#re.sub The documentation does not mention \0 as an alias to it. Although \1 to \9 works. I guess this alias (\0 <=> \g<0>) existed in old python version, but it is not the case any more. In python 2.7 and 3.3: > import re; re.compile(r'123').sub(r'@\0@',"ab123cd") 'ab@\x00@cd' # KO > import re; re.compile(r'123').sub(r'@\g<0>@',"ab123cd") 'ab@123@cd' # OK
