# Exercise 1: Calculate Area of a Triangle
#
# Write a function named `calculate_area_triangle` that takes the base and height of a triangle and returns the area.
# The area formula is (base * height) / 2.
#
# Examples:
# calculate_area_triangle(10, 5) should return 25.0.
# calculate_area_triangle(7, 3) should return 10.5.
#
# Define your function and call it below.


def calculate_area_triangle(base, height):
    return (base * height) / 2


print("Exercise 1:", calculate_area_triangle(7, 3))


# Exercise 2: Calculate Simple Interest
#
# Write a function named `simple_interest` that takes principal, rate of interest (as a percentage), and time (years).
# Calculate and return the simple interest using the formula (principal * rate * time) / 100.
#
# Examples:
# simple_interest(1000, 5, 2) should return 100.
# simple_interest(1500, 3.5, 5) should return 262.5.
#
# Define your function and call it to see the result.


def simple_interest(principal, ROI, time):
    return (principal * ROI * time) / 100


print("Exercise 2:", simple_interest(1500, 3.5, 5))


# Exercise 3: Apply a Discount
#
# Write a function named `apply_discount` that takes a product's price and a discount percentage (from 0 to 100).
# Return the new price after applying the discount.
#
# Examples:
# apply_discount(100, 25) should return 75.
# apply_discount(80, 10) should return 72.
#
# Define your function and call it to display the discounted price.


def apply_discount(Pprice, dis):
    return Pprice - (Pprice * (dis / 100))


print("Exercise 3:", apply_discount(80, 10))


# Exercise 4: Convert Temperature
#
# Write a function called `convert_temperature` that takes a
# temperature and a unit ('C' for Celsius, 'F' for Fahrenheit)
# and converts the temperature to the other unit.
# The formula for converting Celsius to Fahrenheit is (Celsius * 9/5) + 32.
# The formula for converting Fahrenheit to Celsius is (Fahrenheit - 32) * 5/9.
#
# Examples:
# convert_temperature(0, 'C') should return 32.0.
# convert_temperature(32, 'F') should return 0.0.
#
# Define the function and then call it below.


def convert_temperature(temp, unit):
    if unit == "C":
        return (temp * 9 / 5) + 32
    else:
        return (temp - 32) * 5 / 9


print("Exercise 4: Convert 0°C to Fahrenheit:", convert_temperature(0, "C"))
print("Exercise 4: Convert 32°F to Celsius:", convert_temperature(32, "F"))


# Exercise 5: Sum to N
#
# Write a function named `sum_to` that takes a single integer n and returns the sum of all integers from 1 to n.
#
# Examples:
# sum_to(6) should return 21.
# sum_to(10) should return 55.
#
# Define the function and then call it below.


def sum_to(one_num):
    sum = 0
    for num in range(one_num + 1):
        sum += num
    return sum


print("Exercise 5:", sum_to(10))


# Exercise 6: Find the Largest Number
#
# Write a function named `largest` that takes three integers as arguments and returns the largest of them.
#
# Examples:
# largest(1, 2, 3) should return 3.
# largest(10, 4, 2) should return 10.
#
# Define your function and test it with different inputs.


def largest(*args):
    large = args[0]  # assume first is the largest num
    for num in args:
        if num > large:
            large = num
    return large


print("Exercise 6:", largest(10, 4, 2))


# Exercise 7: Calculate a Tip
#
# Create a function called `calculate_tip`. It should take the bill amount and the tip percentage (as a whole number).
# The function should return the amount of the tip.
#
# Examples:
# calculate_tip(50, 20) should return 10.
#
# Write your function and test its output below.


def calculate_tip(bill, tipPrc):
    return bill * (tipPrc / 100)


print("Exercise 7:", calculate_tip(50, 20))


# Exercise 8: Calculate Product of Numbers
#
# Write a function named `product` that takes an arbitrary number of numbers, multiplies them, and returns the product.
# Review your notes on *args for handling an arbitrary number of arguments.
#
# Examples:
# product(-1, 4) should return -4.
# product(2, 5, 5) should return 50.
#
# Define the function and call it with different sets of numbers to test.


def product(nN, *args):
    FProdunct = nN
    for mult in args:
        FProdunct *= mult
    return FProdunct


print("Exercise 8:", product(2, 5, 5))


# Exercise 9: Basic Calculator
#
# Create a function named `basic_calculator` that takes three arguments:
# two numbers and a string representing an operation ('add', 'subtract', 'multiply', 'divide').
# Perform the provided operation on the two numbers. In operations where the order of numbers is important,
# treat the first parameter as the first operand and the second parameter as the second operand.
#
# Examples:
# basic_calculator(10, 5, 'subtract') should return 5.
# basic_calculator(10, 5, 'add') should return 15.
# basic_calculator(10, 5, 'multiply') should return 50.
# basic_calculator(10, 5, 'divide') should return 2.
#
# Define the function and then call it below.


def basic_calculator(Fnum, Snum, oper):
    if oper == "subtract":
        return (lambda num1, num2: num1 - num2)(Fnum, Snum)
    elif oper == "add":
        return (lambda num1, num2: num1 + num2)(Fnum, Snum)
    elif oper == "multiply":
        return (lambda num1, num2: num1 * num2)(Fnum, Snum)
    elif oper == "divide":
        return (lambda num1, num2: num1 / num2)(Fnum, Snum)


print("Exercise 9 Result:", basic_calculator(10, 5, "subtract"))
print("Exercise 9 Result:", basic_calculator(10, 5, "add"))
print("Exercise 9 Result:", basic_calculator(10, 5, "multiply"))
print("Exercise 9 Result:", basic_calculator(10, 5, "divide"))
