Re: [Tutor] How Match a Dot?

I tried that in the re test program (Perl style-re tester) provided
with Pyton 2.4 and ... Ah, I used /.  It works. But I also used \.
Well, I see the culprit. I had one too many \d in: dateRe =
re.compile(r'v\d\d\d\d\d\d\d\d_\d\d\d\d\d\d\.\d\d.*')
Got it. Thanks.

There must be some sort of escape.

  
  
Assuming you want to match in a regular _expression_, use \ as an escape
and use raw strings.

In [40]: import re

In [41]: m=re.search(r'\.', 'abc.de')

In [43]: m.start()
Out[43]: 3

How do I match a dot in, for example, abc.txt? I want to match it
exactly. There must be some sort of escape.
