You can simplify this considerably:

user_input = []  # list is a keyword so makes a bad variable name.

while len(user_input) < 10:
    print '\nNo.', len(user_input) + 1, ', h or t? '
    pre_user = raw_input()
    if pre_user not in ["h","t"]:   # Note you can also use <code>not
in "ht"</code>
        print '\njust enter \'h\' or \'t\' please'
        continue
    user_input.append(pre_user)

print user_input

HTH.
