Here is an alternative suggestion:

def func(s):
    for c in 'aeiouAEIOU':
        s = ''.join(s.split(c))
    return s

When you do:

for j in new_string:
    ...
    new_string.remove(...)

you are modifying a list while looping on it (see e.g. strange result when removing item from a list).

You could simply skip vowels when you create new_list in the first place:

for i in letter:
  if not i in 'aeiou':
    new_string.append(i)
final = ''.join(new_string)

You don't need two loops for this!

letter = 'raeiou'
new_string = letter
vowels = ('a', 'e', 'i', 'o', 'u')
for i in letter:
    if i in vowels:
        new_string = new_string.replace(i,"");
print('The string after removing the vowels is {}'.format(new_string))
