                     If a = 8, b = 2 and c = 20, then what will be the output of the following statements:

                     1.   print(a > b and b < c)    =    _____________________
                     2.  print(a ** b + c)            =   _____________________
                     3.  print(a, b, c)         =    _____________________
                     4.  print(a > b or b > c)   =   _____________________
                     5.  print(a // b – 2 + c)    =   _____________________



                  There are situations in life where we must make decisions based on the circumstances. For example,
                  if it rains, we will stay at home, or else we will visit the market. Similar situations arise in programming
                  as well, where we need to make some decisions and, based on these decisions, execute a set of
                  commands. Whether the outcome is true or false, we must decide which action to take and which
                  statement to execute. In this chapter, we will learn about conditional statements in Python.



                         CONDITIONAL STATEMENTS


                  Conditional  statements,  also  known as  decision-making  or control  flow statements,  are used  in
                  programming to execute different blocks of code based on certain conditions. The following conditional
                  statements are available in Python:
                     if statement
                     if...else statement

                     Nested if statement
                     if…elif…else ladder
