I keep getting the answer of not even or odd regardless of which numbers I enter in this program

def is_list_even(my_list):

x = 0

while x < len(my_list):

if x % 2 != 0:

return False

x= x + 1

return True

def is_list_odd(my_list):

x = 0

while x < len(my_list):

if x % 2 == 0:

return False

x = x + 1

return True

if __name__ == '__main__':

num_Vals = int(input())

input_list = []

for x in range(num_Vals):

input_list.append(num_Vals)

if is_list_even(input_list):

print('all even')

elif is_list_odd(input_list):

print('all odd')

else:

print('not even or odd')
