How can you modify this code to check if val is either a string or a list using type()?
if type(val) == str:
    print("String")
Aif type(val) == str and list:
Bif type(val) == (str, list):
Cif type(val) in ('str', 'list'):
Dif type(val) == str or type(val) == list:
Step-by-Step Solution
Solution:
  1. Step 1: Understand the goal

    We want to check if val is either a string or a list.
  2. Step 2: Evaluate options

    if type(val) == str or type(val) == list: uses 'or' with two type comparisons correctly. if type(val) == (str, list): incorrectly compares to a tuple. if type(val) in ('str', 'list'): compares to strings incorrectly. if type(val) == str and list: uses 'and' incorrectly.
  3. Final Answer:

    if type(val) == str or type(val) == list: -> Option D
  4. Quick Check:

    Use 'or' to check multiple types with type() [OK]
Quick Trick: Use 'or' to combine multiple type() checks [OK]
Common Mistakes:
MISTAKES
  • Using 'and' instead of 'or'
  • Comparing to tuple directly
  • Misusing 'in' without context
