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 variable total_charge, which is formatted to two decimal places. The .2f specifies 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
