Why my second lambda function is not work

Question

# add with lambda
add = lambda a,b: a + b
print(add(4,5))

even =""lambda a: a%2==0
print(even(10))

Answer 1

The only wrong Thing I can see are the quotation marks in the second Function.

add = lambda a,b: a + b
print(add(4,5))

Output is '9', that's right.

even = lambda a: a%2==0
print(even(10))

Output is 'True', that's right, too.

Answer 2

Sebastian can you also solve this
def to_power(num , *args):
if args:
return (i**num for i in args)
else:
return "U didn't pass any input'"
print(to_power(2, *[2,3,4]))

Answer 3

i unpacked the list but still this not working
