Q: What will be the output of the following Python code?
def f(i, values = []):
values.append(i)
return values
f(1)
f(2)
v = f(3)
print(v)Solution: Execute in the shell to verify
Q: What will be the output of the following Python code? numbers = [1, 2, 3, 4] numbers.append([5,6,7,8]) print(len(numbers))

addItem(mylist)
print(len(mylist))Solution: + will append the element to the list.
Q: What will be the output of the following Python code?
def increment_items(L, increment):
i = 0
while i < len(L):
L[i] = L[i] + increment
i = i + 1
values = [1, 2, 3]
print(increment_items(values, 2))
print(values)Solution: Execute in the shell to verify.
