Nothing about this message makes any sense to me. The function 
display_friends() has no body.  Code for load_friends() is missing.  You 
seem to be confusing variable names with literal strings. You open an 
input file "friends.csv", but never use the file handle.  You store the 
return value of load_friends() in d, but never use it.  The "desire 
outcome" includes lots of stuff that this code won't be producing.

And I cannot understand the question you ask at the end.  However, one 
thing I see that's wrong is the user is apparently typing a leading and 
trailinb blank on the line.  If you want to strip out whitespace before 
and after, just use strip().
