Use variable with regular expression in python.

Question

How do i use a variable inside the regular expression given below.
v = re.findall(r'/VARIABLE/(\d\d\d)">', html)

Answer 1

The simplest would be to build the regex pattern by concatenating what is before the string variable, the variable itself and what is after it.

v = re.findall(VARIABLE+r'(\d\d\d)">', html)

Answer 2

concatenation!! haha. the answer was so simple yet it had worried.

Answer 3

Sure :)
Anyway, there are lots of good libraries for HTML parsing, you could try 'beautifulsoup' for example.
It makes the whole data scraping a loooot easier :)
