1.Describe the difference between a chained conditional and a nested conditional. Give your own example of each. Do not copy examples from the textbook. # A conditional statement with a series of alternative branches while a nested conditional statement appears in one of the branches of another conditional statement. peter=42 john=33 if john > peter: print('john is taller than peter') elif john < peter: print('john is shorter than peter') else: print('either john or peter is taller') OUTPUT: john is shorter than peter peter=42 john=42 if peter > john: print('peter is taller than john') if peter == john: print('either peter or john is taller') else: print('john is taller than peter') OUTPUT: either peter or john is taller 2. Deeply nested conditionals can become difficult to read. Describe a strategy for avoiding nested conditionals. Give your own example of a nested conditional that can be modified to become a single conditional, and show the equivalent single conditional. Do not copy the example from the textbook. # the strategy of avoiding nested conditionals is by using logical operator ‘and’ and ‘or’ a=23 b=23 c=25 d=27 if a < b: print('I am less than 30') if b == c: print('I am equivalent to 30') if c > d: print('I am greater than 30') else: print('none of us is above 30') OUTPUT: none of us is above 30 a=23 b=23 c=25 d=27 if a < b or b == c or c > d: print('I am less than 30') print('I am equivalent to 30') print('I am greater than 30') else: print('none of us is above 30') OUTPUT: none of us is above 30
