Hi, @debasisnath !

Well an error happens because of the space between function and colon.

Also Check all the indentation. And look at this:

try:
    # Tries to do something
except Error:
    # Goes here if gets error
else:
    # Gets here only if no exception AND try doesnt have return or any other stopper like abort.

I think the problem may be "valueerror" instead of "ValueError"
