The list comprehension will iterate over the list and create a new list with a boolean for each value. The value of the boolean depend of the type of the element. Then, all() will check if all the elements in the sequence is True.

array_a = [{"name": "john", "address": "usa"},
          {"name": "adam", "address": "china"}]
array_b = ["Country", "State"]
array_c = ["Country", "State", {"name": "adam", "address": "china"}]

print(all(isinstance(elem, str) for elem in array_a))
# False
print(all(isinstance(elem, str) for elem in array_b))
# True
print(all(isinstance(elem, str) for elem in array_c))
# False

If you don't know this form of statement [<expression> for <variable> in <iterable>], this is how it works: Data Structures - List Comprehensions
