# n+1 in for loop

Hi, Could you please explain for i in range(1, n+1)

Thank you

Hey Shekhar,

Thanks for reaching out!

The following line of code:

`for i in range(1, n+1)`

is the start of a `for`

loop that will iterate over a sequence of numbers generated by the `range()`

function.

Here's a breakdown:

- The `range()`

function includes the start value but **excludes** the end value. Therefore, `range(1, n+1)`

generates a sequence of numbers starting from `1`

and ending at `n`

. To include `n`

in the sequence, you'd specify `n+1`

as the end value.

- `for i in ...`

iterates over each number in that sequence, and with each iteration, the variable `i`

will take on the next value in the sequence.

For example, if `n=5`

, the loop will iterate over the values 1,2,3,4, and 5. In each iteration, you can use the value of `i`

inside the loop to perform some operation or computation.

For a more in-depth explanation, please refer to the following lecture from the course:

Hope this helps.
