Why this happened?

When I'm writing-
count = 0
while count <= 10:
   count = count+1
   if count % 2 == 0:
      continue
   print(count)
In the third line, of the code I'm writing, count = count+1.But if I write this line at the end of the code it's not giving any output. While writing another one code like the code below- 
count = 0

while count <15:
   if count == 5:
      break
   print(count)
   count += 1
I'm writing count = count+1 at the last of the code and yet getting output , why is this happening?why I'm not able to write count = count+1 at the last of the code in the 1st one set?Please answer me.
And
When I sit to solve a problem , I probably get confused by loops(in case of solving a problem).I can't understand when should I use 'while loop' and when should I use 'for loop'! So, please help me to overcome this one confusion.

Answer 1

The key factor here is not the position of 'count = count + 1', but rather the 'continue' statement.

'continue' just dimisses everything after it, and not before it. So in your case, when the counter%2==0, then everything after that conditional will not be executed. Thus if you write count=count+1 before it will run, but if you write it after then it won't.

Thank you for your valuable answer.
