Create a function len_str that uses a built-in function to return the number of characters in the passed string str. Then print the result of a call to len_str passing in the string I love Python!. It should return 14.

        def len_str(str):
---
def len_str(str) #paired
---
    return len(str)
---
    Return len(str) #paired
---
print(len_str("I love Python!"))
---
print(len_str(I love Python!)) #paired

Create a function called bmi that takes height (in inches) and weight (in pounds) as parameters. It should calculate the ‘’bmi’’ by squaring the height then dividing the weight by the height squared and then converting to metric by multiplying by 703. Watch your indentation!

        def bmi(height, weight):
---
    heightSquared = height * height
---
    BMI = weight / heightSquared
---
    BMImetric = BMI * 703
---
    return BMImetric

Write two functions. The first is square(x), which returns x squared. The second function is sum_of_squares(x,y,z), which returns the sum of the squares of three numbers z, y, and z. For example, square(2) should return 4 and sum_of_squares(2, 4, 6) should return 56. For example, square(2) should return 4 and sum_of_squares(2, 4, 6) should return 56.

        def square(x):
---
    y = x * x
---
    return y
---
def sum_of_squares(x, y, z):
---
    a = square(x)
    b = square(y)
    c = square(z)
---
    return a + b + c

Create a function called average(num1, num2), which finds the average of two numbers num1 and num2. For example, average(10,4) should return 7.0. Note: there are two extra code blocks, and watch your indentation!

        def average(num1, num2):
---
def average(num1, num2) #paired

You are driving a little too fast, and a police officer stops you. Create a function called caught_speeding(speed, is_birthday) which returns the type of ticket the police officer will give you. If speed is 60 or less, the result is "no ticket". If speed is between 61 and 80 inclusive, the result is "minor ticket". If speed is 81 or more, the result is "major ticket". All this is true, unless it is your birthday – on that day, your speed can be 5 higher in all cases. Note: there are two extra code blocks and lots of indentation to watch out for!

        def caught_speeding(speed, is_birthday):
---
    if is_birthday:
---
        if speed <= 65:
---
        if speed < 65: #distractor
---
            return "no ticket"
---
        elif speed <= 85:

            return "minor ticket"

Create a check_guess(guess, target) function which computes if a guess is too low, too high, or correct compared to the target. Return 'too low' if guess is less than target, 'correct' if they are equal, and 'too high' if guess is greater than target. For example, check_guess(5, 7) returns 'too low', check_guess(7, 7) returns 'correct', and check_guess(9, 7) returns 'too high'. Note: there are three extra code blocks, and watch your indentation!

        def check_guess(guess, target):

Put the code blocks below to define the function alarm_clock. It will be given a day of the week encoded as 0 = Sun, 1 = Mon, 2 = Tue, …6 = Sat, and a boolean indicating if we are on vacation, and will return a string indicating when the alarm clock should ring. If we are on vacation and it is a weekend (0 = Saturday or 6 = Sunday), it should return "off", and otherwise return "10:00".
