A little question about "continue" in the loop "while".

What happens if I put a "continue" in a while loop.

I believe that the "continue" reset the loop and start again the code in the while.

Is it okay?

You are correct. Using continue in a while loop will go to the next iteration of the loop, ignoring any code blocks after the continue.

For example:

counter = 5
while counter > 0:               
    counter = counter -1
    if counter == 3:
        continue
    print 'Current count:', counter

This code will count down from 5 to 0 and print the current number. However, if the number is 3, the continue statement will skip the print and go to the next number. The output looks like this:

Current count: 4
Current count: 2
Current count: 1
Current count: 0

Using continue in a while (or a for) loop is valid syntax, and is OK to do.
