• Conditions with the if statements can also be written within (). It is totally optional.
• else statement is optional and if required can be only one else statement in one if block.
• It is must to specify colon (:) after writing a condition with the if statement.
• The number of statements (also called as a block) written within if can be of any size.
Let us understand the flow of conditional statements:
if (Condition):
Num=int(input("Enter the number: "))
statements to be executed if a condition evaluates
if Num>9 and Num<100:
to True
print("Two Digit Number")
always indented
if (Condition): Num=int(input("Enter the number: "))
Statements for True will be executed if Num>0:
else: print("Positive Number")
Statements for False will be executed else:
print("Negative Number")
if (Condition): Num=int(input("Enter the number: "))
Statements for condition1 will be executed if Num%2==0:
elif (Condition): print("Even Number")
Statements for condition2 will be executed elif Num%3==0:
elif (Condition):
print("Multiple of 3")
Statements for condition2 will be executed
elif Num%5==0:
.
print("Multiple of 5")
.
else:
.
print("Invalid Number")
else:
Statements executed when all above conditions are
False
Few examples of conditional statements:
[1]: Age=int(input("Enter the age: "))
if Age>18:
print("Eligible for Voting")
else:
print("Not Eligible for Voting")
Enter the age: 25
Eligible for Voting
[2]: Year=int(input("Enter year: "))
if Year%4==0 or Year%100==0 and Year%400==0:
print("Leap Year")
else:
print("Not a Leap Year")
Enter year: 2025
