Given a predicate function, fn, and a prop string, this curried function will then take an object to inspect by calling the property and passing it to the predicate.
Return a lambda function that takes an object and applies the predicate function, fn to the specified property.
def check_prop(fn, prop):
return lambda obj: fn(obj[prop])
check_age = check_prop(lambda x: x >= 18, 'age')
user = {'name': 'Mark', 'age': 18}
check_age(user) # True
