New to Python; trouble understanding the output of a for loop statement-CodePudding

With an input of

And the code:

stop = int(input())
result = 0
for n in range(10):
    result  = n   2
    if result > stop:
        break
    print(n)
print(result)

The result is:

0
1
9

I'm still pretty new to Python and coding in general. I don't know if I'm going down the right path in trying to "translate" the code in my head into something more digestible? Here's how I read it:

We start with 0. We assign the variable n, and there are 10 n in the range. We take the result variable, and add itself n 2. Itself is 0, n is 0, so result becomes 2. Since the variable result is less than the input, which is 6, we print n, which is 0. So that part I get.

The next output is 1. I get that because it's the next n in range. And result then increases to n n 2, which would be 2 2 2. So we're at six, now. The output being 0, 1, I get. The next one I feel like should be 2? But it's 9. Why? Where does this 9 come from?

CodePudding user response：

The 9 is coming from the print(result). You broke out of the loop because 9 > 6, so you don't do any more print(n) calls.

CodePudding user response：

Your print(result) is outside your loop, so you print(n) on the first two loop (0, 1) then it breaks and you print results which is (2 3 4=9).

CodePudding user response：

At each step of the loop result increases by n 2, at each step n increases by 1

Step 0
result = 0

Step 1
n = 0
result = 0 (0 2) = 2
-> 0 is printed

Step 2
n = 1
result = 2 (1 2) = 5
-> 1 is printed 

Step 3
n = 2
result = 5 (2 2) = 9
result is greater than 6: loops break

-> 9 is printed
