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.
