    After the if condition, on the next line, write an indented block of statements. When the condition
                      evaluates to true, the block of statements given below it is executed; otherwise, it is skipped and
                      control flows to the statement after if.

                      Here, if the age of the user is more than or equal to 18, ‘Eligible’ will be printed, otherwise nothing
                      will be printed.

                      Program 1. To demonstrate the use of the ‘if’ statement.
                          Program1.py

                       File  Edit  Format   Run    Options   Window    Help

                       age=int(input("Enter Age: "))
                       if(age>=18):
                           print("You are eligible to cast a vote")

                          Output

                       Enter Age: 20

                       You are eligible to cast a vote
                       Enter Age: 16

                      Program 2. To greet the user based on the time entered.

                          Program2.py
                       File  Edit  Format   Run    Options   Window    Help

                       time=int(input("Enter Time in 24-hour format: "))
                       if (time<12):
                           print("Good Morning")

                          Output

                       Enter Time in 24-hour format: 6                                   Write a Python program to enter a
                       Good Morning                                                      number. If it is less than 0, display:
                                                                                              ‘Negative numbers are
                       Enter Time in 24-hour format: 18
                                                                                                  not allowed’.

                      IF … ELSE … STATEMENT
                      The if…else… statement lets your program choose between two options. Python checks the
                      condition; if it’s true, it executes statement block 1 after the if statement—otherwise, it executes
                      statement block 2 after the else statement.
