Break and Continue: While Loops

[Elizabeth Weiss]

CODE #1:

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

------
I understand that i=0 and i will only be printed if 1=1
The results of this is
0
1
2
3
4
Breaking

Why is Breaking going to be printed if i only goes up to 4? It does say if i>=5? Shouldn't this mean that the results should be:
0
1
2
3
4
5

CODE #2:

i=0
while True:
   i=i+1
  if i==2:
     print("Skipping 2")
     continue
  if i==5:
     print("Breaking")
     break
   print(i)

------

Questions:
1. what does the word True have to do with anything here? 
2. i=i+1- I never understand this. Why isn't it i=i+2?
3. Do the results not include 2 of 5 because we wrote if i==2 and if i==5?
4. How is i equal to 2 or 5 if i=0?

Thanks for all of your help!
