Implement a function is$\_$all$\_$strings that accepts a single iterable and returns True if it contains ONLY strings. Otherwise, it should return false. Print

is$\_$all$\_$strings$([\text{'}$a$\text{'},\text{'}$b$\text{'},\text{'}$c$\text{'}])$ #True

is$\_$all$\_$strings$([2,\text{'}$a$\text{'},\text{'}$b$\text{'},\text{'}$c$\text{'}])$ #False

is$\_$all$\_$strings$((\text{'}$hello$\text{'},$ 'goodbye'$))$ #True
