Return and print without assigning a variable?

Question

Curiously, is there a way for both printing and returning within a single function without assigning output to a variable?

Consider this code:

def secret_number(secret_number_range): return random.randrange(1, secret_number_range + 1) 

Is there a way to refer to this variable stored for the return statement?

Answer 1

I think there is no direct or “easy” way to do this. However, one way would be to define a decorator that prints this. For instance:

  import random def print_return(func): def func_wrapper(param): rv = func(param) print("Return value: {0}".format(rv)) return rv return func_wrapper @print_return def secret_number(secret_number_range): return random.randrange(1, secret_number_range + 1) # with this, this call would result in "Return value: 3" being printed. c=secret_number(4)
