I'm just having fun, but can it be done better?

oob = lambda name: ''.join([letter if letter not in "aeiouAEIOU" else "oob" for letter in name])
oob("Name")

Outputs >>>"Noobmoob"

Maybe a translation table?

>>> mapping = str.maketrans({letter: "oob" for letter in "aeiou"})
>>> oob = "nilamo".translate(mapping)
>>> oob
'noobloobmoob'

Or a regular expression:

>>> import re
>>> re.sub("[aeiou]", "oob", "nilamo")
'noobloobmoob'

That's a bad use of lambda. You should only use lambda for single use functions passed as a parameter. Otherwise define a function. Here's a better use of lambda for this case:

oob = ''.join(map(lambda letter: 'oob' if letter.lower() in 'aeiou' else letter, 'Ichabod'))

Granted, but that's not what I asked about.
