                  Let’s PLug-in


                    State whether the following statements are true or false.
                    1.    A low-level language is a programming language that is machine
                      dependent.                                                                       __________
                    2.    Python provides two commonly used functions input() and print() for input
                       and output.                                                                     __________
                    3.   Variables are memory reference points where we store values which can be

                       accessed or changed later.                                                       __________
                    4.   Assignment operators are used to compare the value of the two operands
                       and returns True or False accordingly.                                           __________




                 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



                                                                                    Conditional Statements in Python  103
