Why python re module does not work with @? [duplicate]

Question

In the following example shows weird problem: Python pattern does not work.

import re
data = r'blah blah @Component blah blah'
m = re.match(r'\@Component', data)
print m

It would print out:

None

What did I miss here?

Answer 1

You need to use re.search instead, and @ has no special meaning so you do not need to escape it.

>>> re.search(r'@Component', data).group()
'@Component'

Answer 2

match tries to match the pattern at the beginning of the string. Use search instead. Also, @ doesn't have any special meaning in Python's regex, so you don't need to escape it.

Working code:

>>> re.search('(@Component)', data).groups()
('@Component',)
