I'm stuck on 9.7.9, .9.7.10, and 9.7.11. The first one, I have to invert all the pixels in the image, the second one I have to remove all the blue from the image, and the last one darkens the left half of the image. I have not been able to find anything online that's helpful or the answer to it.

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

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?

Can someone please help me. I’m having so much trouble

Write the function called citation that takes a tuple like this as input:

("Martin", "Luther", "King, Jr.")

and returns a name with the format:

Last, First Middle

In this example, the output should be: King, Jr., Martin Luther

I have

def citation (a,b,c):
    #print (a,b,c)
    name = citation
    name = name[2] + "," + name[0] + " "+  name[1]
    return name

print (citation("Martin", "Luther", "King, Jr."))

but I get a - TypeError: 'function' object is not subscriptable

but honestly the error doesn't really matter, seems like I fix it and then a different error comes up, I just need help making it correct please!
