Nested If Statement: Diploma in Python Programming: Nested If Statements | Alison
Nested if Statements
Your challenge
Please use python language with Nested if statements:
- Calculate total to charge for an order from an online store in the USA
- ask user what country they from and their order total
country = input("which country are you from?")
order_total = float(input("what's your order total?")
# Initialize the total charge with the order total
total_charge = order_total
- if the user from USA, ask which state
if country.lower() == "usa":
state = input("Which state are you from? ")
- if the order is from outside USA do not charge any taxes
- If the order was placed in USA, calculate tax based on states: Louisiana charge 1% sales taxes, all other states charge 3% sales tax.
if state.lower() == "louisiana":
tax_rate = 0.01 # 1% sales tax for Louisiana
else:
tax_rate = 0.03 # 3% sales tax for all other states
# Calculate the total charge including tax
total_charge += order_total * tax_rate
else:
# No tax for orders outside the USA
tax_rate = 0.00
# Print the total charge
print(f"Your total charge is: ${total_charge:.2f}")
--------------------------
# Ask the user for their country and order total
country = input("Which country are you from? ")
order_total = float(input("What's your order total? "))
# Initialize the total charge with the order total
total_charge = order_total
# Check if the user is from the USA
if country.lower() == "usa":
state = input("Which state are you from? ")
# Check if the state is Louisiana
if state.lower() == "louisiana":
tax_rate = 0.01 # 1% sales tax for Louisiana
else:
tax_rate = 0.03 # 3% sales tax for all other states
# Calculate the total charge including tax
total_charge += order_total * tax_rate
else:
# No tax for orders outside the USA
tax_rate = 0.00
# Print the total charge
print(f"Your total charge is: ${total_charge:.2f}")
------------------
Notes 1:
# Initialize a variable
total = 10
# Use the += operator to add 5 to the total
total += 5 # This is equivalent to total = total + 5
# Print the result
print(total) # Output: 15
Notes 2:
meaning: print(f"Your total charge is: ${total_charge:.2f}")
The line print(f"Your total charge is: ${total_charge:.2f}") is using an f-string, which is a way to format strings in Python introduced in version 3.6.
Here’s a breakdown of what it does:
f"...": This indicates that the string is an f-string. It allows you to embed expressions inside curly braces{}that are evaluated at runtime.Your total charge is:: This is a literal string that will be printed as is.${total_charge:.2f}: Inside the curly braces, you have the variabletotal_charge, which is formatted to two decimal places. The.2fspecifies that you want to format the number as a float with two digits after the decimal point.
So, if
total_charge were 10.456, the output would be: 10.46-------------------
