While    join is more pythonic  and the correct answer for this problem  it is indeed possible to use a for loop   If this is a homework assignment  please add a tag if this is so    and you are required to use a for loop then what will work  although is not pythonic  and shouldn t really be done this way if you are a professional programmer writing python  is this   endstring      mylist     first    second    other   for word in mylist    print  This is the word I am adding      word   endstring   endstring   word print  This is the answer I get      endstring   You don t need the  prints   I just threw them in there so you can see what is happening

That s not how you do it    gt  gt  gt     join   first    second    other     firstsecondother    is what you want   If you do it in a for loop  it s going to be inefficient as string  addition  concatenation doesn t scale well  but of course it s possible     gt  gt  gt  mylist     first    second    other    gt  gt  gt  s       gt  gt  gt  for item in mylist         s    item      gt  gt  gt  s  firstsecondother

If you must  this is how you can do it in a for loop   mylist     first    second    other   endstring      for s in mylist    endstring    s   but you should consider using join        join mylist
