Question

I am trying to match a text in a file

In [44]: with open(path) as f:
   ....:     for line in f:
   ....:         matched = re.search('^PARTITION BY HASH',line)
   ....:         if matched is not None:
   ....:             print matched.group()
   ....:

The file contains lines like
PARTITION BY HASH(SOME_THING);
And also some other lines among which there is
SUBPARTITION BY HASH(SOME_THING) which shouldn’t be matched

After the match i would like to delete that line.
But the print matched.group fails why ?

Answer 1

something like this:

In [29]: strs1="PARTITION BY HASH(SOME_THING)"

In [30]: strs2="SUBPARTITION BY HASH(SOME_THING)"

In [31]: bool(re.match(r"^PARTITION BY HASH",strs1))
Out[31]: True

In [32]: bool(re.match(r"^PARTITION BY HASH",strs2))
Out[32]: False
