How to join entries in a set into one string

Question

Basically  I am trying to join together the entries in a set in order to output one string  I am trying to use syntax similar to the join function for lists  Here is my attempt   list     gathi-109   itcg-0932   mx1-35316   set 1   set list  set 2   set   mx1-35316    set 3   set 1 - set 2 print set 3 join         However I get this error  AttributeError   set  object has no attribute  join   What is the equivalent call for sets

Set s do not have an order - so you may lose your order when you convert your list into a set  i e     gt  gt  gt  orderedVars     0    1    2    3    gt  gt  gt  setVars   set orderedVars   gt  gt  gt  print setVars   4    2    3    1     Generally the order will remain  but for large sets it almost certainly won t   Finally  just incase people are wondering  you don t need a      in the join    Just      join set

I wrote a method that handles the following edge-cases    Set size one  A      join   abc    will return  a  b  c   My desired output was  abc   Set including integers  Empty set should returns        def set to str set to convert  separator                set size   len set to convert          if not set size              return            elif set size    1               element     set to convert             return str element          else              return separator join map str  set to convert

You have the join statement backwards try   print      join set 3

I think you just have it backwards   print      join set 3

Nor the set nor the list has such method join  string has it       join set   a   b   c       By the way you should not use name list for your variables  Give it a list   my list or some other name because list is very often used python function

Sets don t have a join method but you can use str join instead        join set 3    The str join method will work on any iterable object including lists and sets   Note  be careful about using this on sets containing integers  you will need to convert the integers to strings before the call to join   For example  set 4    1  2       join str s  for s in set 4

join set 3    The join is a string method  not a set method
