while x <= 5:
    print(x ** 2)
    x += 1

Write a while loop that prints out the value of x plus 10 while x is less than or equal to 15 and the remainder of x divided by 5 is 0. Be careful not to end up with an infinite loop!

x = 10

20

while x <= 15 and x % 5 == 0:
    print(x + 10)
    x += 1

Write a while loop that prints out the value of x times y while x is greater than or equal to 5 and less than 10, and prints out the result of x divided by y when x becomes 10. Be careful not to end up with an infinite loop!

x = 5
y = 2

while x >= 5 and x < 10:
    print(x * y)
    x += 1
else:
    print(x / y)

Write code that will iterate over the x and y lists and multiply each element of x with each element of y, also printing the results to the screen.

Hint: use nesting!

x = [2, 4, 6]
y = [5, 10]

for i in x:
    for j in y:
        print(i * j)

Write code that will iterate over the x and y lists and multiply each element of x that is greater than 5 with each element of y that is less than 12, also printing the results to the screen.

Hint: use nesting!

x = [2, 4, 6, 8]
y = [5, 10, 15, 20]

for i in x:
    for j in y:
        if i > 5 and j < 12:
            print(i * j)

Write code that will iterate over the x and y lists and multiply each element of x with each element of y that is less than or equal to 10, also printing the results to the screen. For ys elements that are greater than 10, multiply each element of x with y squared.

            print(i * j)
        else:
            print(i * j ** 2)

Write code that will print out each character in x doubled if that character is also inside y. Hint: use nesting!

x = "cryptocurrency"
y = "blockchain"

for i in x:
    if i in y:
        print(i * 2)

Write code that will iterate over the range generated by range(10) and for each element  that is between 3 and 7 inclusively print out the result of multiplying that element by the third element in the same range.

Hint: use nesting!

my_range = range(10)

6

10
12
14

for i in my_range:
    if 3 <= i <= 7:
        print(i * my_range[2])

Write code that will iterate over the range starting at 5, up to but not including 25, with a step of 5, and for each element that is between 10 and 21 inclusively print out the result of multiplying that element by the second to last element of the same range. For any other element of the range (outside [10-21]) print Outside! Finally, after the entire range is exhausted print out The end!

Hint: use nesting!

Outside!
150
225

The end!

for i in range(5,25,5):
    if 10 <= i <= 21:
        print(i * range(5,25,5)[-2])
    else:
        print("Outside!")
else:
    print("The end!")

Insert a break statement where necessary in order to obtain the following result:

x = [1, 2]
y = [10, 100]

    for j in y:
        if i % 2 == 0:
            break
            print(i * j)
        print(i)
    print(j)

Insert a continue statement where necessary in order to obtain the following result:

x = [1, 2]
