Nested If Statement
A nested if statement is a construct in programming where an if statement is placed within another if statement’s
block. This allows for the evaluation of multiple conditions in a hierarchical manner. In Python, indentation is crucial for
defining the scope of each if statement.
The syntax of nested if statement is shown below:
if (Test Expression1):

if (Test Expression2):
Indented block 1
else:
Indented block 2
else:
Indented block 3

Program 17: To demonstrate the use of the nested if statement
# Input the total purchase amount
total_purchase_amount = float(input("Enter the total purchase amount: Rs. "))
# Initialize the discount rate and discounted amount
discount_rate = 0

discounted_amount = 0
# Calculate the discount rate and discounted amount based on the total purchase amount
if total_purchase_amount >= 10000:
discount_rate = 0.10 # 10% discount
print(f"Congratulations! You get a 10% discount.")
else:
if total_purchase_amount >= 5000:
discount_rate = 0.05 # 5% discount
print(f"Congratulations! You get a 5% discount.")

else:
print("You are not eligible for getting discount!!")
# Calculate the discounted amount
discounted_amount = total_purchase_amount - (total_purchase_amount * discount_rate)
# Output the final amount after applying the discount
print(f"Total Amount: Rs. {total_purchase_amount:.2f}")
print(f"Discount Rate: {discount_rate * 100}%")
print(f"Discounted Amount: Rs.{discounted_amount:.2f}")
Output:

Enter the total purchase amount: Rs. 5500
Congratulations! You get a 5% discount.
Total Amount: Rs. 5500.00
Discount Rate: 5.0%
Discounted Amount: Rs. 5225.00
