Hey All,
I have been playing around with REs and could not get the following
code to run.
import re
vowel = r'[aeiou]'
re.findall(vowel, r"vowel")
anything wrong I have done?
Regards,
Atul.

Yes. You didn't paste the traceback into your message.
>>import re

re.findall(vowel, r"vowel")
['o', 'e']
It works as expected here.

>import re

['o', 'e']
It works as expected here.

When I key this input in IDLE it works but when I try to run the
module it wont work.

What's the name of your script? What happens when you run it? Does it print
a traceback? If so, what does it say? Please cut and paste, don't

Heureka!
The same file when I use with the following does not work.
import re
vowel =
r'[u"\u093e"u"\u093f"u"\u0940"u"\u0941"u"\u0942"u"\u0 943"u"\u0944"u"\u0945"u"\u0946"u"\u0947"u"\u0948"u "\u0949"u"\u094a"u"\u094b"u"\u094c"]'
print re.findall(vowel, u"\u092f\u093e\u0902\u091a\u094d\u092f\u093e",
re.UNICODE)
atul@atul-desktop:~/Work/work/programs$ python fourth.py
[]
atul@atul-desktop:~/Work/work/programs$
is this the way to use Unicode in REs?

No, u"..." is part of the string, not the character. The regex becomes
# untested
vowel = u'[\u093e\u093f\u0940\u0941\u0942\u0943\u0944\u0945\u 0946\u0947\u0948\u0949\u094a\u094b\u094c]'

Unfortunately you cannot embed arbitrary Python string constants
(u"...") in regular expressions. What does work is something like:
>>vowel = u'[\u093e\u093f\u0940\u0941\u0942\u0943\u0944\u0945\u 0946\u0947\u0948\u0949\u094a\u094b\u094c]'
re.findall(vowel, u"\u092f\u093e\u0902\u091a\u094d\u092f\u093e")
[u'\u093e', u'\u093e'] This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics
