Python Remove Comma In Dollar Amount

Question

Using Python v2, I have the user entering an amount into a string as below:

RawPurchaseAmount = raw_input(\"Please enter purchase amount: \")

PurchaseAmount         


        

Answer 1

>>> x = '$10,00.00'
>>> ''.join(e for e in x if e.isdigit() or e == '.')
'1000.00'

Remove the $, any other character, except a digit or a . in one go.
