I'm confused how the "while" statement works.

Question

I'm just don't understand how while works. Can someone explain it to me?

Answer 1

syntax:

while <condition>:
<statement>
<statement>
...
<after while loop>

explanation:
1. the condition is evaluated;
2. if the condition is true, execute the statements; if it is false jump to what comes after the while loop
3. start over from step 1.

Answer 2

Suppose you want to draw the black balls from a Box having 10 balls.

noOfBalls = 10
while(noOfBalls not equal to 0):
#keep on drawing the balls
noOfBalls-=1

So you need to keep on drawing the balls till the box becomes empty.

so if you take a condition after writing while, then the loop within that while statement will keep on getting executed till the condition is satisfied.

Answer 3

until condition is true, while loop is executes
while (i>10) now the statements in while are executes until the valid of i is greater than 10
