  2. [40pts] Assuming the following definitions, fill in the table. 
    
a = b"hello world"
b = "hello world"
c = 0b1101 
d = 0x73
    Possible types are:
      str, int, bytes, float     		 
    expressiontypevalue
    a[1]
    b[1]
    c | 0x10
    c & 0x10
    chr(d ^ 0x40)
    d >> 4
    c / 2
    c // 2
    c % 7
    (-c) % 7
  3. [10pts] What is the output of the following code, and why? 
    def f(a, b, c):
  a = 3; b[0] = "t"; c['k'] = "hello"

x = 1
y = [1]
z = {'k':0}
f(x,y,z)
print(x, y, z)

    Output:

Why:
  4. [15pts] What is the output of each of the following pieces of code? Explain. 
    a = "hello"
def f():
  print(a)

f()

def f():
  global a
  a = "jello"
  print(a)

f()
print(a)
