The line
/************
is a (beginning of a) comment in C/C++/C#/Java and other languages. In Python, that is not a comment and causes a syntax error. Just delete all the comments with the welcome message.
In Python, you start a comment with the hash symbol: #. Alternatively, you can mark things as a string literal that would have a similar effect as a comment if you never assign it to a variable:
# This is a comment
''' This also works as a comment '''
print('Hello!')
If you still have problems that you cannot overcome, please, share your entire code.
Good luck!
