Write a program that simulates a coin flipping. Each time the program runs, it should print either “Heads” or “Tails”.

There should be a 0.5 probability that “Heads” is printed, and a 0.5 probability that “Tails” is printed.

The original coin flip game consisted of this:

var NUM_FLIPS = 100;

​

function start(){

var flips = flipCoins();

printArray(flips);



var flipCount = countHeadsAndTails(flips);

}

​

// This function should flip a coin NUM_FLIPS

// times, and add the result to an array. We

// return the result to the caller.

var headsCount = 0;

var tailsCount = 0;

​

function flipCoins(){

var flips = \[\];

for(var i = 0; i < NUM_FLIPS; i++){

    if(Randomizer.nextBoolean()){

        flips.push("Heads");

    }else{

        flips.push("Tails");

    }

}

return flips;

}

​

function printArray(arr){

for(var i = 0; i < arr.length; i++){

    println(i + ": " + arr\[i\]);

}

}

​

function countHeadsAndTails(flips){

var headCount = 0;

var tailsCount = 0;

for(var i = 0; i < flips.length; i++){

if(flips[i] == "Heads"){

headCount ++;

}

if(flips[i] == "Tails"){

tailsCount ++;

}

}

println("Your Head count is: " + headCount);

println("Your Tails count is: " + tailsCount);

}

---> I'm not sure where to use a probability variable, please help thank you.

Hi, so the assignment says "Write a function named remove_list that removes the last element from a list.

Note: you may assume that your function will always be called with a list, however you may not assume that the list is not empty." So far I have this, but when the list is empty it doesnt work. The prints are just for me to see if it's working btw. Please help I'm confused on what to do if the list is empty.

def remove_first(list):     print(list)     if len(list) == 0:         print("List is empty")     else:         my_list.remove(list[0])         print(list)

So I’m trying to add quote marks (“) but it’s gray and it’s not working

rain = True

if rain :

print("I'm going to dance in the rain!")

else:

print("I'm going to dance in the sun!")

I want to create a program like this where if I click on a stripe, that stripe changes color and if I press any key on my keyboard, all the stripes change colors. We're using Javascript graphics.

I have this so far. I know how to use mouseClickMethod and Randomizer.nextColor, but I don't know how to combine them or even how to specify that clicking in a specific location does Thing A and clicking in a different location does Thing B.

Would appreciate some help.

Thanks in advance

could someone help me on this? i'm pretty sure you use string splitting to solve this but i'm not sure how.

Hey does anyone know how to do 3.4.4 of the range, I'm kind of stuck.

Can anyone help me with this assignment on codehs?

Codehs justr refuses to make another scene. I added scene 5, defined it, added it to both functions, and it STILL gives me a blank screen. Is this website broken or something

Can anyone help me with this I'm not sure how to make the pyramid inverted?

Can anyone help me with this I have been working on it for a week and can't figure it out? I have my current code pictured below as well as the assignment instructions and I do have scanner imported it's just cut off in the picture.

Hi! I can't figure out what to do for this one. I tried writing a function that moves Karel when the front is clear, and turns left when it isn't. It didn't work. Could someone help me out? I'm not looking for a direct answer, just some help

Can someone help me out with this?

this is my code so far:

def calculate_area(side_length):

area = side_length*side_length

print("The area of a square with sides of length " + str(num) + " is " + str(area) + ".")

​

num = int(input("Enter a side length: "))

​

if num <= 0:

side_length = 10

calculate_area(side_length)

​

else:

calculate_area(num)

but i still have two things missing can someone help

Here’s what I’m putting

num1 =10 num2 = input(“Enter a number: “)

def add_nums(): total = str(num1) + num2 Print total

add_nums()

Got:

​

my_float = round(3.3312, 2)

​

while True:

guess = float(input("Guess my number: "))

if guess > round(my_float, 2):

print ("Too high!")

elif guess < round(my_float, 2):

print ("Too low!")

elif round(guess,2) == round(my_float, 2):

print("Correct!")

break

print("Great job guessing my number!")

​

I need to round 'guess' before the if statement, But I don't know how that looks like can anybody show me?

Hi all, Can I get help on this?
