on executing above code, interpretor throwing syntax error saying syntax error as below.

 print(?The sum of ?, x, ? and ?, y, ? is ?, sum, ?.?, sep=??)

SyntaxError: invalid syntax

Answer 1

The single quote used in the print statement is ' with ascii value 39.

>>> ord("'")
39

The one ’ used in the print statement in the question is not a quote ' but RIGHT SINGLE QUOTATION MARK' (U+2019)

>>> u"’"
u'\u2019'

Since, you are using python 2, to use sep in the print statement you need to import the functionality from the future.

from __future__ import print_function
print('The sum of ', x, ' and ', y, ' is ', x+y, '.', sep='')

Answer 2

It's because of those wacky quote characters like ’. Change them to ' characters and you should not have any problem.

Answer 3

First, replace the ’ by '

Second, you may need to add one more sentence: from __future__ import print_function
