Conditional Statement in Python

This Statement is used to solve the condition based program using if,elif, and else statement.

It provides a block-level statement to write code without using curly brackets. Block will be managed by indent.

Indent provides structure to write code using the outer statement and inner statement.
all parallel statements of the same indent will work as an outer and after press tab or space it will be an inner indent.

if condition:
  statement  //inner statement
statement//outer statement

 Type of Conditional Statement:-

1 If:- when the condition will be true then we can use simple if statement

if condition:

2 If--else:-

it will work when the condition is true or false.

if condition:

WAP to increase mark of a student with five grace marks if the entered subject mark is <33 otherwise the same mark will be displayed?

3 Nested if-else:-

   it is used to solve more than one condition based problem without using the logical operator.
   nested should not be preferred for the complex conditions because python not provide block-level syntax easily.

if condition:
   if condition:
  if condition:

WAP to check divisibility from 3 and 5 both of any entered numbers without using logic and operator?

num = int(input("enter number"))
if num%3==0:
    if num%5==0:
        print("divisible by 3 and 5 both")
        print("Only divisible by 3 not five")
    if num%5==0:
     print("divisible by 5")
     print("not divisible by 3 and 5") 

4 Ladder if--else:-

Ladder means step by step, it will execute the first if statement when it will false then process to next
statement continuously when none of the statements will be true then it will execute else statement.

if condition:
elif condition:
elif condition:

Q) WAP to check vowel and consonant using nested and ladder both?

Q) WAP to Calculate Marksheet using five different subjects with the following condition.

1 all subject marks should be 0 to 100.

2 if only one subject mark is <33 then suppl.

3 if all subject marks is >33 then percentage and division should be calculated.

4 if a student is suppl then five bonus mark can be applied to the student to be pass then the student will be passed by grace.

5 Display Grace Subject name, distinction subject name,suppl subject name and failed subject name.

Q) WAP to check the greatest using four different numbers using a ladder and nested both?

5 Multiple If:-

Multiple Condition with multiple results.

WAP to check divisibility of number that number is divisible by 3,5 and 9 with all combinations?



WAP to check leap year?

WAP to check the greater number?

WAP to find a middle number in three different numbers?

WAP to check the greatest number?

WAP to check that salary is in income tax criteria or not .if in income tax then display income tax slave.
