Randomize characters in string but keep formatting

So I have string such as: 

id = 'ee9baadc-46bc-4486-a78b-830f5b2bcfc9'

How can I go about randomizing the characters of the string, but keeping the dashes in the same location, such as:

id2 = '9eebaadc-46bc-4846-7a8b-380f5b2bcf9c'

This is what I have currently, but it scrambles the dash locations as well:

id2 = ''.join(random.sample(id,len(id)))

You can randomize each section and preserve dash locations using split (on dashes), sample to randomize each sub-list and a couple of joins to tie it all back together:

from random import sample

id_ = 'ee9baadc-46bc-4486-a78b-830f5b2bcfc9'
id_ = "-".join("".join(sample(s, len(s))) for s in id_.split("-"))

Avoid calling variables id--it overwrites a builtin function.

base_id = 'ee9baadc-46bc-4486-a78b-830f5b2bcfc9'
base = base_id.split('-')[0]
random_base = ''.join(random.sample(base,len(base)))
id = re.sub(r'ee9baadc', random_base, base_id)

this will suffice, randomizes first set of chars...if I wanted to, I could iterate on that over the entire string.
