The while Loop

while <expr>:
    <statement(s)>
    <break> #will take you out of the loop
    <statements>
    <continue>
    <statements>

<statements> #break will bring you here


Example:
x = 10
 while x > 0:
    x -= 1
    if x == 5:
        break
    if x == 8:
        continue #Don't print when its 8
    print(x)

print("outside loop")
