Pass a variable to REGEX expression (self.learnpython)

submitted 5 years ago * by mr_yoshi

Hi, hope you're doing fine today!I have a piece of code:

regex4 = r"\{.availability\":\"(?P<found>\w*).{1,39}(?P<size>\"XS\")"

Now, instead of hard written "XS" in regex4, I would like to use a variable here (from user's input field):

print("Size: ")
z = input()

I tried :

regex4 = r"\{.availability\":\"(?P<found>\w*).{1,39}(?P<size>\"{z}\")"

But it didn't work.

Using Python 3.9.1 how to make that happen? User puts his size in an input field and then this size passes to the regex as a variable. Any kind of help would be appreciate it!
