Describe the difference between a chained conditional and a nested conditional. Give your own example of each. Do not copy examples from the textbook.
 
Well, chained conditionals are usually at the same level, that means we have only one level of branching _main_ >>  ( if - elif -else)
 
While the nested conditionals contain multiple levels of branching, __main__ >> first_level of branching ( if >> second_level_of_branching( if >> third_level … -elif-else )  - elif - else )
