- The way your code handles the variable `i` within the `for` loop seems to indicate a wrong understanding of the meaning of
- for i in range(1,n+2):
`range(1,n+2)` will provide an object of type `range`. This object represents the sequence of numbers from `1` to `n+2`. At the begin of each iteration the next element from that sequence is fetched and assigned to `i`, _no matter what happened to `i` in between_.- In other words, you can not "skip" elements from the `range` object just by incrementing `i` within the `for` loop. You can see this with the help of the following example code:
- for i in range(3):
- print("Value of i at start of loop body: i = ", i)
- i += 20
- print("Value of i after modification: i = ", i)
