문제

Go ahead and create a function, spam, that prints the string "Eggs!" to the console. 

Don't forget to include a comment of your own choosing (enclose it in triple quotes!).

문제

We've set up a function, square. 

Call it on the number 10 (by putting 10 between the parentheses of square()) on line 9!

문제

Check out the function in the editor, power.

It should take two arguments, a base and an exponent, and raise the first to the power of the second.

It's currently broken, however, because its parameters are missing.

Replace the ___s with the parameters base and exponent and call power on a base of 37 and a power of 4.

문제

Let's look at the two functions in the editor: one_good_turn (which adds 1 to the number it takes in as an argument) 

and deserves_another (which adds 2).

Change the body of deserves_another so that it always adds 2 to the output of one_good_turn.

문제

1.First, def a function called cube that takes an argument called number. Don't forget the parentheses and the colon!

2.Make that function return the cube of that number (i.e. that number multiplied by itself and multiplied by itself once again).

3.Define a second function called by_three that takes an argument called number.

4.if that number is divisible by 3, by_three should call cube(number) and return its result. Otherwise, by_three should return False.

Don't forget that if and else statements need a : at the end of that line!

문제

Before we try any fancy importing, let's see what Python already knows about square roots. 

On line 3 in the editor, ask Python to

which we would expect to equal five.

문제

You'll need to do two things here:

1. Type import math on line 2 in the editor.

2. Insert math. before sqrt() so that it has the form math.sqrt(). 

   This tells Python not only to import math, but to get the sqrt() function from within math.

Then hit Save & Submit to see what Python now knows.

문제

Let's import only the sqrt function from math this time.

(You don't need the () after sqrt in the from math import sqrt bit.)

문제

Use the power of from module import * to import everything from the math module on line 3 of the editor.

문제

The code in the editor will show you everything available in the math module.

Click Save & Submit Code to check it out (you'll see sqrt, along with some other useful things like pi, factorial, and trigonometric functions).

문제

Try out the max() function on line 3 of the editor.

You can provide any number of integer or float arguments to max().

문제

Go ahead and set minimum equal to the min() of any set of integers or floats you'd like.

문제

Set absolute equal to the absolute value of -42 on line 2

문제

Have Python print out the type of an int, a float, and a str string in the editor. 

You can pick any values on which to call type(), so long as they produce one of each.

문제

1. First, def a function, shut_down, that takes one argument s. Don't forget the parentheses or the colon!

2. Then, if the shut_down function receives an s equal to "yes", it should return "Shutting down"

3. Alternatively, elif s is equal to "no", then the function should return "Shutdown aborted".

4. Finally, if shut_down gets anything other than those inputs, the function should return "Sorry"

문제

Import the math module in whatever way you prefer. 

Call its sqrt function on the number 13689 and print that value to the console.

문제

1. First, def a function called distance_from_zero, with one argument (choose any argument name you like).

2. If the type of the argument is either int or float, the function should return the absolute value of the function input.

3. Otherwise, the function should return "Nope"

문제

Write a function called answer that takes no arguments and returns the value 42.

Even without arguments, you will still need parentheses.

Don't forget the colon at the end of the function definition!

문제

Define a function called hotel_cost with one argument nights as input.

The hotel costs $140 per night. So, the function hotel_cost should return 140 * nights.

문제

1. Below your existing code, define a function called plane_ride_cost that takes a string, city, as input.

2. The function should return a different price depending on the location, similar to the code example above. Below are the valid destinations 

   and their corresponding round-trip prices.

"Charlotte": 183

"Tampa": 220

"Pittsburgh": 222

"Los Angeles": 475

문제

1. Below your existing code, define a function called rental_car_cost with an argument called days.

2. Calculate the cost of renting the car:

3. Every day you rent the car costs $40.

4. if you rent the car for 7 or more days, you get $50 off your total.

5. Alternatively (elif), if you rent the car for 3 or more days, you get $20 off your total.

6. You cannot get both of the above discounts.

7. Return that cost.

Just like in the example above, this check becomes simpler if you make the 7-day check an if statement and the 3-day check an elif statement.

문제

1. Below your existing code, define a function called trip_cost that takes two arguments, city and days.

2. Like the example above, have your function return the sum of calling the rental_car_cost(days), hotel_cost(days), and plane_ride_cost(city) 

    functions.

It is completely valid to call the hotel_cost(nights) function with the variable days. Just like the example above where we call double(n) with the

 variable a, we pass the value of days to the new function in the argument nights.

문제

1. Modify your trip_cost function definition. Add a third argument, spending_money.

2. Modify what the trip_cost function does. Add the variable spending_money to the sum that it returns.

문제

After your previous code, print out the trip_cost( to "Los Angeles" for 5 days with an extra 600 dollars of spending money.

Don't forget the closing ) after passing in the 3 previous values!
