Hello all
I am trying to solve this problem[1] using regular expression. I wrote this
code but I am getting time limit exceed. Could some one please tell me how to
make this code run faster.
import re
if __name__ == "__main__":
n = int ( raw_input() )
c = 1
while c <= n :
email = filter ( lambda x : x != None , [ re.search (
'[^~!@#$%^&*()<>?,.]*[a-zA-Z0-9][a-zA-Z0-9._][a-zA-Z0-9._][a-zA-Z0-9._][a-zA-Z0-9._][a-zA-Z0-9._]*@[a-zA-Z0-9]+.(com|edu|org|co.in)[^~!@#$%^&*()<>?,.a-zA-Z0-9]*'
, x ) for x in raw_input().split(' ') ] )
t = len ( email )
print 'Case #' + str ( c ) + ': ' + str ( t )
for i in xrange ( t ):
print email[i].group()
c += 1
Also rather than breaking the string at space, I tried to use findall but I am
not getting correct result.
>>> re.findall (
>>> '[^~!@#$%^&*()<>?,.]*[a-zA-Z0-9][a-zA-Z0-9._][a-zA-Z0-9._][a-zA-Z0-9._][a-zA-Z0-9._][a-zA-Z0-9._]*@[a-zA-Z0-9]+.(com|edu|org|co.in)[^~!@#$%^&*()<>?,.a-zA-Z0-9]*[
>>> ]+','mukeshtiwari.iiitm...@gmail.com mukeshtiwari.iiitmm...@gmail.com')
['com']
I am suppose to get [ mukeshtiwari.iiit...@gmail.com ,
mukeshtiwari.iiit...@gmail.com] ?
