PYTHON WHILE LOOP [ SOLVED ]

Question

tracker = 0
while tracker <= 2:
tracker += 1
print(tracker)

Output : 1, 2, 3

Now my question is why it count 3 ? Anyone explain please .

Answer 1

Let's jump to the point where 2 is printed, so tracker is 2.
Next the condition (tracker <= 2) is checked and 2 <= 2 is true.
Then tracker is incremented to 3, and 3 is printed.
Then condition 3 <= 2 is false and execution ends

Answer 2

When tracker is 2, the loop still considers the statement true and goes again. This then is why tracker can increase to three and output it. All you have to do is remove the equal sign in the condition or put the print statement after the increment.

Answer 3

Thanks Benjamin Jürgens and Gabriel <3

Answer 4

tracker <=2 and goes thru the loop again

Answer 5

Technically its just because your print(tracker) is placed after the increment instruction.
Put the print(tracker) before tracker += 1 and see

Answer 6

Why cause <=. Less than or equal to.

Answer 7

The tracker variable is incremented before printing, hence it also prints 3!

Answer 8

2=2 positive loops one more time
3=2 negative breaks and program ends in 3
