Using a loop, write numbers from -20 to 20. Then write:

def funk_4():

#The first 6 numbers
for item in range(-20, 21)[0:6]:
    print(item)

#The last 6 numbers
for item in range(-20, 21)[35:41]:
    print(item)

# All even numbers
for item in range(-20, 21):
    if item%2 == 0:
        print(item)

# All numbers except 5
for item in range(-20, 21):
    if item != 5:
        print(item)

# All numbers up to and including 7
for item in range(-20, 21)[0:28]:
