# Mixed-up Code Questions¶

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.

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!

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.

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!

Create a function called `swapValues(val1, val2)`

, which takes two values and swaps them.
It then returns val1. For example, `swapValues(8,2)`

should return `2`

. Note: there is an extra code block, and
watch your indentation!

Write a function called `swapValues(val1, val2)`

, which takes two values and swaps them. It then returns val1. For example, `swapValues(8,2)`

should return `2`

Create a function called `get_avg_drop_lowest(num_list)`

which returns the average of a list of numbers, ignoring the lowest value. However, if the list only contains one value, then return that. For example, `get_avg_drop_lowest([90])`

returns `90`

, `get_avg_drop_lowest([90, 10])`

also returns `90`

, and `get_avg_drop_lowest([90, 10, 0])`

returns `50`

.

Create a function called `compare(p1, p2)`

which returns whichever is greater of its two parameters. Note:
there are two unused code blocks.

Write a function called `compare(p1, p2)`

which returns whichever is greater of its two parameters.

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!

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'`

.

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"`

. If we are not
on vacation and it is a weekend, it should return `"10:00"`

, and otherwise return
`"7:00"`

. Note: there are two extra code blocks, and watch your indentation!

First create a function called `square_it`

which
squares the parameter `n`

and returns the result. Then, create a function called `cube_it`

which cubes
the parameter `n`

and returns the result. Note : there are three extra code blocks, and watch your indentation!

Create a function called `distance`

which returns the distance between two coordinates using
the distance formula: d = √((x_2 - x_1)² + (y_2 - y_1)²). Use two functions in Python’s math module (`math.pow`

, `math.sqrt`

).
The function `math.pow(a,b)`

returns `a`

raised to the `b`

power. The function `math.sqrt(a)`

returns the square root of `a`

.
