That is because you are using single quote for main string as well as '*'.

Python interprets it as -

print( f'Hey, {Username}, your password is {'# string ends here.
*' * Password}. The password is **{len(Password)}** long.')

The last bracket goes unmatched and hence the error.

A quick fix would be to use double quotes in one of the strings.

print(f'Hey, {Username}, your password is {"*" * Password}. The password is **{len(Password)}** long.')
