Answer 1

i = 0
while True:
  print(i)
  i = i + 1
  if i >= 5:
    print("Breaking")
    break

print("Finished")

// Here you are printing i (which is 0) before incrementing it. That's why it will start from 0

Answer 2

i = 0
while i<5:
  i += 1
  if i==3:
    print("Skipping 3")
    continue
  print(i)

Here you incremented the i value (which was 0 and now it's 1 after incrementing) before printing it, that's why you get 1 and not a 0
