Python generate string based on regex format -


i have difficulties learning regex in python. want parse tornado web route configuration along arguments request path string without handlers request.path method. example, have route patterns like:

/entities/([0-9]+)

/product/([0-9]+/actions

the expected result combine integer parameter (123) string like:

/entities/123

/product/123/actions

how generate string based on pattern?

thank in advance!

this might possible duplicate to:
reversing regular expression in python
generate string matches regex in python

using answer provided @bjmc solution works this:

>>> import rstr >>> intermediate = rstr.xeger(\d+) >>> path = '/product/' + intermediate + '/actions'

depending on how long want intermediate integer, replace regex: \d{1,3}
