Why python regexps look expecting a begin match, but not an ending one?
My impression is that the regexps behave a little bit odd:
>>> import re
>>> r=re.compile("test")
>>> r.match("test")
<re.Match object; span=(0, 4), match='test'>
>>> r.match("1test")
>>> r.match("test2")
<re.Match object; span=(0, 4), match='test'>
>>> r.match("1test2")
>>>
I have also tried python-pcre, it behaves on the same way. If the "regexp" is only a single word, it should behave as a substring match (or a full-line match). It seems matching lines starting with "test", but not the ones ending with it (or containining it somewhere).
Why?

The documentation for re.match(...) is explicit that it only matches at position 0.
If you're asking this question, what you probably want is re.search(...) to match at any point within the string.
