 18.1.2. Understanding If construct

02:40

The general syntax of if statement in Python is,

If test expression:   
	 statement(s)  

• The if-construct is a selective construct. The statements within the if block are executed only once when the condition evaluates to True. Otherwise, the control goes to the first statement after the if-construct.
• In Python, the body (block of statements) of the If statement is indicated by indentation and the first unindented line marks the end.
• Python interprets non-zero values as True. None and 0 are interpreted as False.

Here is a simple program to illustrate the simple if-statement:

if (12 % 2 == 0):
	 print("12 is divisible by 2") # Notice the Indentation
print("Execution done")

Write a program to check whether the given integer is divisible by 3 or not, and print the result to the console as shown in the examples.

Sample Input and Output 1:

num: 66
divisible by 3
End of program

Sample Input and Output 2:

num: 52
End of program

EXAMPLE PROGRAM

num = int(input("num: "))
if(num%3==0):
    print("divisible by 3")
    print("End of program")

else:
    print("End of program")
