So  i have this problem  I got tuple  1 2 3  which i should print with string formatting  eg   tup    1 2 3  print  this is a tuple  something     tup    and this should print tuple representation with brackets  like     This is a tuple  1 2 3    But I get TypeError  not all arguments converted during string formatting instead   How in the world am I able to do this  Kinda lost here so if you guys could point me to a right direction

Talk is cheap  show you the code    gt  gt  gt  tup    10  20  30   gt  gt  gt  i   50  gt  gt  gt  print   d       s   i tup  50   10  20  30   gt  gt  gt  print   s   tup    10  20  30   gt  gt  gt

gt  gt  gt  thetuple    1  2  3   gt  gt  gt  print  this is a tuple   s     thetuple   this is a tuple   1  2  3    Making a singleton tuple with the tuple of interest as the only item  i e  the  thetuple   part  is the key bit here

Even though this question is quite old and has many different answers  I d still like to add the imho most  pythonic  and also readable concise answer   Since the general tuple printing method is already shown correctly by Antimony  this is an addition for printing each element in a tuple separately  as Fong Kah Chun has shown correctly with the  s syntax   Interestingly it has been only mentioned in a comment  but using an asterisk operator to unpack the tuple yields full flexibility and readability using the str format method when printing tuple elements separately   tup    1  2  3  print  Element s  of the tuple  One  0   two  1   three  2   format  tup     This also avoids printing a trailing comma when printing a single-element tuple  as circumvented by Jacob CUI with replace   Even though imho the trailing comma representation is correct if wanting to preserve the type representation when printing    tup    1    print  Element s  of the tuple  One  0   format  tup

This doesn t use string formatting  but you should be able to do   print  this is a tuple     1  2  3    If you really want to use string formatting   print  this is a tuple  s    str  1  2  3     or print  this is a tuple  s      1  2  3      Note  this assumes you are using a Python version earlier than 3 0

Please note a trailing comma will be added if the tuple only has one item  e g   t    1   print  this is a tuple     format t    and you ll get    this is a tuple  1      in some cases e g  you want to get a quoted list to be used in mysql query string like   SELECT name FROM students WHERE name IN   Tom    Jerry      you need to consider to remove the tailing comma use replace            after formatting because it s possible that the tuple has only 1 item like   Tom     so the tailing comma needs to be removed   query string    SELECT name FROM students WHERE name IN     format t  replace              Please suggest if you have decent way of removing this comma in the output

You can try this one as well   tup    1 2 3  print  this is a tuple  something   format something tup     You can t use  something with  tup  just because of packing and unpacking concept with tuple

Try this to get an answer    gt  gt  gt d     1    2     gt  gt  gt  print  Value   s    d   Traceback  most recent call last     File   lt stdin gt    line 1  in  lt module gt  TypeError  not all arguments converted during string formatting   If we put only-one tuple inside     it makes a tuple itself    gt  gt  gt   d    1    2     This means the above print statement will look like   print  Value   s     1    2    which is an error   Hence    gt  gt  gt   d      1    2      gt  gt  gt     Above will be fed correctly to the print s arguments

Note that the   syntax is obsolete  Use str format  which is simpler and more readable   t   1 2 3 print  This is a tuple  0   format t

gt  gt  gt  tup    1  2  3   gt  gt  gt  print  Here it is   s     tup   Here it is   1  2  3   gt  gt  gt    Note that  tup   is a tuple containing a tuple  The outer tuple is the argument to the   operator  The inner tuple is its content  which is actually printed    tup  is an expression in brackets  which when evaluated results in tup    tup   with the trailing comma is a tuple  which contains tup as is only member

t    1  2  3     the comma     concatenates the strings and adds a space print  this is a tuple    t     format is the most flexible way to do string formatting print  this is a tuple  0   format t     classic string formatting   I use it only when working with older Python versions print  this is a tuple  s    repr t  print  this is a tuple  s    str t

I think the best way to do this is   t    1 2 3   print  This is a tuple   s    str t    If you re familiar with printf style formatting  then Python supports its own version  In Python  this is done using the     operator applied to strings  an overload of the modulo operator   which takes any string and applies printf-style formatting to it   In our case  we are telling it to print  This is a tuple     and then adding a string   s   and for the actual string  we re passing in a string representation of the tuple  by calling str t     If you re not familiar with printf style formatting  I highly suggest learning  since it s very standard  Most languages support it in one way or another

Besides the methods proposed in the other answers  since Python 3 6 you can also use Literal String Interpolation  f-strings     gt  gt  gt  tup    1 2 3   gt  gt  gt  print f this is a tuple  tup    this is a tuple  1  2  3

Many answers given above were correct  The right way to do it is    gt  gt  gt  thetuple    1  2  3   gt  gt  gt  print  this is a tuple   s     thetuple   this is a tuple   1  2  3    However  there was a dispute over if the     String operator is obsolete  As many have pointed out  it is definitely not obsolete  as the     String operator is easier to combine a String statement with a list data   Example    gt  gt  gt  tup    1 2 3   gt  gt  gt  print  First   d  Second   d  Third   d    tup First  1  Second  2  Third  3   However  using the  format   function  you will end up with a verbose statement   Example    gt  gt  gt  tup    1 2 3   gt  gt  gt  print  First   d  Second   d  Third   d    tup  gt  gt  gt  print  First      Second      Third      format 1 2 3   gt  gt  gt  print  First   0 0    Second   0 1    Third   0 2    format tup   First  1  Second  2  Third  3 First  1  Second  2  Third  3 First  1  Second  2  Third  3   Further more      string operator also useful for us to validate the data type such as  s   d   i  while  format   only support two conversion flags    s  and   r
