My script returns no values

Your code should return a string, not print a string. Replace the print statements in donuts(), both_ends() fix_start() and mix_up() with code that creates and returns a string to be printed by test(). For example, donuts() should look like this:

def donuts(count):
    if count < 10:
        return 'Number of donuts: ' + str(count)
    return 'Number of donuts: many'

And when testing in the interpreter you should call main().

Output:
>>> main()
donuts
 OK  got: 'Number of donuts: 4' expected: 'Number of donuts: 4'
 OK  got: 'Number of donuts: 9' expected: 'Number of donuts: 9'
 OK  got: 'Number of donuts: many' expected: 'Number of donuts: many'
 OK  got: 'Number of donuts: many' expected: 'Number of donuts: many'

both_ends
 OK  got: 'spng' expected: 'spng'
 OK  got: 'Helo' expected: 'Helo'
 OK  got: '' expected: ''
 OK  got: 'xyyz' expected: 'xyyz'

 OK  got: 'ba**le' expected: 'ba**le'
 OK  got: 'a*rdv*rk' expected: 'a*rdv*rk'
 OK  got: 'goo*le' expected: 'goo*le'
 OK  got: 'donut' expected: 'donut'

mix_up
 OK  got: 'pox mid' expected: 'pox mid'
 OK  got: 'dig donner' expected: 'dig donner'
 OK  got: 'spash gnort' expected: 'spash gnort'
