str1 = "apple"

str2 = str1

str2 += "s"

print(str1)

What would the code above have as an output?

• apple

• apples

• s

• str1

Related to previous question:

Why was the output "apple"?

• Python string are mutable

• Python string are immutable

How do we use shallow/deepcopy?

• We just call the respective functions

• Depends on my computer

• Import then call the respective functions

lst1 = [1, 2, 3]

lst2 = [2, 4, 6]

lst2[2] = [5]

print(lst1)

What's the output of this code?

• [1,2,3]

• [1,5,3]

• [1,2,5]

• [2,4,6]

lst1 = [1, 2, 3]

lst2 = lst1

lst2[1] = 9

print(lst1)

What is the output of the code above?

• [1,2,3]

• [1,2,9]

• [9,2,3]

• [1,9,3]
