“Can only join an iterable” python error

Question

I\'ve already looked at this post about iterable python errors:

"Can only iterable" Python error

But that was about the error \"cannot assign an iterab

Answer 1

splitlist1.reverse(), like many list methods, acts in-place, and therefore returns None. So tobereversedlist1 is therefore None, hence the error.

You should pass splitlist1 directly:

splitlist1.reverse()
reversedlist = ' '.join(splitlist1)

Answer 2

string join must satisfy the connection object to be iterated(list, tuple)

splitlist1.reverse() returns None, None object not support iteration.
