Set default value and type for parameter

Question

How can I do something like this:

def profile(request, pk=0 : int):
    #to do

I need pk to be int (without converting in function).

Like this:

def profile(request, pk: int):

If pk empty - set value to 0 and type to int.

Answer 1

My code works for any input type of pk: integer, string with integer, string without integer

import re
    def intCheck(pk):
      contains_number = bool(re.search(r'\d', pk))
      if contains_number:
        return int(re.search(r'\d+', pk).group())
      else:
        return 0

def profile(request, pk=0):
    pk = intCheck(pk)
    print(request + " " + str(pk))

profile('request', "232")
profile('request', 123)
profile('request', "no number")

Output:

request 232
request 123
request 0
