Data Type Filtering

Filter mixed list elements using isinstance() to safeguard processes.

Instructions

  • Given 
    mixed = [42, "hello", 3.14, True, [1, 2], 55, "world"]
  • You want to retrieve only the integers, but 
    True
    is a subclass of int! You must check if the type is exactly 
    int
    or use 
    isinstance
    and not a boolean.
  • Create a list containing only elements where 
    type(item) is int
    . Print the sum of these integers using 
    sum()
    .
