What is Apple?
The output of:
x = "123"
print(x * 2)
What is "123123"?
x = {1, 2, 3}

What is 5?
What the acronym "SQL" stands for
What is Structured Query Language?

What is the error?
def func(x):
x += 1
return x

def mystery(n):
if n == 0:
return 0
return n + mystery(n-1)
Computes the sum of numbers from 1 to n recursively
What is the error?
def factorial(n):
return n * factorial(n - 1)
print(factorial(5))
RecursionError, because there’s no base case, leading to infinite recursion

What is 1101?
What HTTPS stands for
What is HyperText Transfer Protocol Secure?
The first computer bug
What was the first computer bug?
What is the output?
def mystery(n):
return [i * 2 for i in range(n) if i % 2 == 0]
print(mystery(5))
[0, 4, 8], because it doubles only even numbers in range(n), which are [0, 2, 4]
What is the error?
x = 10
def change():
x += 5
print(x)
change()
UnboundLocalError, because x += 5 tries to modify x inside the function without declaring it as global first
