python - Regular expression to match $price -

i in need of regular look matches cost like: $200, $143.

so requirements are, there should spaces before , after cost like: ... $130 ...

and there should dollar sign "$" before digits.

help please.

p.s. using python

something like:

\s\$(\d+)\s

edit:

as avinash raj noted in answer, including spaces in pattern prevent match of sequences of prices. improve way 1 shows lookarounds:

(?<=\s\$)(\d+)(?=\s)

here's demo.
