Why is this regex not matched in python

I need to find "7.1/10" in "7.1/10&nb" with the following regex:

d{1}.?d{0,2}/10

But the following code does not match anything:

rating= "7.1/10&nb"
p = re.compile(re.escape("d{1}.?d{0,2}/10"))
m = p.match(rating)
if m:
    print("rating: {}".format(m.group()))
else:
    print("no match found in {}".format(rating))

What's the problem with my code?
