Challenge: Snake and Sum

Task

Implement the function that can take optional arguments and keyword arguments. This function should return the snake string and summary of integer values.

  1. Define the snake_and_sum() function that should take many arguments and keyword arguments.
  2. Create a loop for iteration on optional arguments:
    • if the argument is a string, append this value to the snake list.
    • if the argument is an integer, add this argument to the summary variable.
  3. Create a loop for iteration on keyword arguments:
    • all keywords are string, append it to the snake list.
    • if the value is an integer, add this value to the summary variable.
  4. The snake_and_sum() function returns a tuple with two values (string and integer). Unpack these values to the variables string and result.
