Answer 1

In this way you can see how the loop works:
in the last loop x become 12. After that the loop again check the value of x. And x is no more smaller than 12. So the loop ends.

x = 7
print("x is",x)
print("while statement run:")
while x<12:
print("while before add x is",x)
x +=1
print("while after add x is",x)
print("while statement end.")
print("But now x is",x)

Answer 2

You can save the code on here on playground. The add in addition a print statement after x+=1 and look what happend.

Answer 3

Please share the code so we easily understand what's your doubt

Answer 4

The orders in your while loop states: print the x, then add 1. The last integer that met the condition was 11, so 11 was printed, then, "behind the scenes" x was updated to 12.
