The if Statement

                  The if statement is the simplest conditional statement. Here, a statement or a collection of statements
                  within the if block is executed only if a certain condition or expression evaluates to True. If the condition
                  evaluates to False, then the control of execution is passed to the next statement after the if block. The
                  syntax of the if statement is given below:

                  Syntax:
                                                                                                              False
                  if (Test Expression):                                                   Test Expression
                      Indented statement block

                  # if block ends here                                                             True


                                                                                             Body of if
                                        Tech Fact

                    In Python, the non-zero value is interpreted as true.
                            None and 0 are interpreted as false.                       Statement just below if







                   Program 1: To check whether a given number is positive.
















                  On running the above program, we get the following output:
