"Note that patterns which start with positive lookbehind assertions will never match at the beginning of the string being searched; you will most likely want to use the search() function rather than the match() function:"

>>> re.match(r'(?<=^)abc', 'abc').group()
'abc'
>>> re.match(r'(?<=\b)abc', 'abc').group()
'abc'
>>> re.match(r'(?<=\A)abc', 'abc').group()
'abc'
>>> re.match(r'(?<=\A)abc', 'abc', re.DEBUG).group()
assert -1 
  at at_beginning_string 
literal 97 
literal 98 
literal 99 
'abc'
>>>


in some cases match() can match
