I solved it

Answer 5

... if len(revrs2) ==16:
for j in range (16)
if revrs2[j] >9:
.............."

Answer 6

if 16<len(my_list)<16:
print('not valid')
It's the same as:
if len(my_list)>16 and len(my_list)<16:
print("not valid")
if the length of my_list is greater than 16 and less than 16, it will print not valid.
How this can even execute in any condition?
It should be:
if len(my_list)>16 or len(my_list)<16:
print("not valid")

Answer 7

# try:

if len(my_list) != 16:
print("not valid")

Answer 8

because if length is equals to 16, your code print a space, and then continue to do the rest of your code (other checks) and finally print "valid" or "not valid" even if the length is different from 16 ^^
