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.

Kind regards,
