Answer 1

2 errors:
arr = ["rolf","golf","solf"]
val = filter(lambda name: name.startswith("r"),(arr))
print(next(val))

Typo in startswith
Lambda needed arr in parenthesis in order to assign value to name

Thank you rodwynnejones and Rik Wittkopp ☺

Answer 3

arr = ["rolf", "golf", "solf", "rock", "and", "roll"]
val = filter(lambda name: name.startswith("r"), arr)
for x in val:
print(x)
