replace vowels

[haye]

is there a way to do it like this ? since i want EVERY vowels to be replaced by '-'

list1 = ['john', 'tony', 'luck', 'o']
 
def replace_vowel(mlist):
    vowels = 'aeiouAEIOU'
    newlist = [c.replace(vowels, '-') for c in mlist]
    return newlist

 
print replace_vowel(list1)

Output:
['john', 'tony', 'luck', '-']

or with:

     newlist = ['-' if c in 'aeiou' else c for c in mlist]
     return newlist

same output
