In Python2  print was a keyword which introduced a statement   print  Hi    In Python3  print is a function which may be invoked   print   Hi     In both versions    is an operator which requires a string on the left-hand side and a value or a tuple of values or a mapping object  like dict  on the right-hand side   So  your line ought to look like this   print  a  d b  d     f x n  g x n      Also  the recommendation for Python3 and newer is to use   -style formatting instead of  -style formatting   print  a   d   b   d   format f x n  g x n      Python 3 6 introduces yet another string-formatting paradigm  f-strings   print f a  f x n  d   b  g x n  d

Other words printf absent in python    I m surprised  Best code is  def printf format   args       sys stdout write format   args    Because of this form allows not to print  n  All others no  That s why print is bad operator  And also you need write args in special form  There is no disadvantages in function above  It s a standard usual form of printf function

Python 3 6 introduced f-strings for inline interpolation  What s even nicer is it extended the syntax to also allow format specifiers with interpolation  Something I ve been working on while I googled this  and came across this old question     print f  account 40s    ratio 3 2f   - gt  AUD  splitAmount      PEP 498 has the details  And    it sorted my pet peeve with format specifiers in other langs -- allows for specifiers that themselves can be expressions  Yay  See  Format Specifiers

Because your   is outside the print      parentheses  you re trying to insert your variables into the result of your print call  print      returns None  so this won t work  and there s also the small matter of you already having printed your template by this time and time travel being prohibited by the laws of the universe we inhabit   The whole thing you want to print  including the   and its operand  needs to be inside your print      call  so that the string can be built before it is printed   print   a  d b  d     f x n   g x n       I have added a few extra spaces to make it clearer  though they are not necessary and generally not considered good style
