list_1 = ["A", "B", "C"]
list_2 = list_1
list_3 = list_2

del list_1[0]
del list_2
print(list_3) - answer['B', 'C']

nums = [1, 2, 3]
vals = nums
del vals[1:2]
print(nums) - answer[1, 3]

i=0
while i <= 3:
i += 2 # On first iteration, i becomes 2
print("*") # 2 is less than 3 so the loop prints another "*"
# Because 2+2 > 3, the loop stops and only 2 "*"s are printed - answer*
*

var = 1
# First iteration, 1 < 10, "#" is printed
# THEN var is incremented
# var << 1 = var * 2^1 = 2

# Second iteration, 2<10, "#" is printed
# 2*2^1 = 4

# Third iteration, 4 < 10, "#" is printed
# 4 * 2^1 = 8

# Fourth iteration, 8 < 10, "#" is printed
# 8 * 2^1 = 16

# 16 > 10, loop stops, 4 "#"s printed

while var < 10:
...print("#")
var = var << 1 - answer#

my_list = [1, 2, 3]

for v in range(len(my_list)):
my_list.insert(1, my_list[v])

print(my_list)

# First iteration: my_list[v] is my_list[0], which is 1
# my_list becomes [1, 1, 2, 3]
# This means that my_list[1] = 1
# # my_list becomes [1, 1, 1, 2, 3] - answer[1, 1, 1, 1, 2, 3]

# Example 1
def wishes():
print("My Wishes")
