Regular expression in Python won't match end of a string

Question

I\'m just learning Python, and I can\'t seem to figure out regular expressions.

r1 = re.compile(\"$.pdf\")
if r1.match(\"spam.pdf\"):
    print \'yes\'
else:
            


        

Answer 1

Your Question

$ means "end of string". So, you need a regex like \.pdf$ to match:

1. A dot (.), escaped because it is a special character in regular expressions.
2. String "pdf"
3. End of string.

Regular expressions go beyond languages, Python or others, so you should read some tutorials about them firstly. Consider regular-expressions.info. This is not a Python question actually, it is a fundamental regular expression question.
