Regular Expressions in Python


Here is the way of matching an expression in Python program. Its absolutely very easy to do this. All that you need to do is importing regular expression re and use re.search(pattern,string).  The below example gives a brief idea of how it is done.

import re
pat=raw_input("Enter the pattern:")
f=open('b.txt', 'r')
l=f.read()
match=re.search(pat,l)
if match :
	print match.group()
else:
	print 'pattern was not found'
