The problem is, that in your script, you're doing something entirely
different than what you do above:
[...]
|    echo $username:$password >> /root/Desktop/programming_lab/tp
[...]
| chpasswd /root/Desktop/programming_lab/tp;

The chpasswd command reads a list of user name and password pairs from
standard input, but you provide nothing as standard input to chpasswd in
your script.
Try
| chpasswd < /root/Desktop/programming_lab/tp
instead.

BTW: what are those ';' you terminate some lines with intended to do?
You're writing a shell script, not C code.
