## Range() in a for Loop 1/2

Imagine that we wish to print numbers from 1 to 100. Naturally, we could do this manually:

But that would be incredibly time-consuming!

If we had to print numbers from 1 to 1,000,000, we'd be counting manually for the rest of our lives!

To tackle this challenge, we'll employ the `for` loop in conjunction with the `range()` function!

Take a look at the following code:

How does the code work?

The `range()` function provides a sequence of numbers that starts at 0 (by default) when the initial limit is unspecified. It increments by 1 (by default) until it reaches a final limit (the final limit itself is not included).

The format of the `range()` function is: `range(start, end, step)`.

If our intention is to operate with decreasing numbers, we can achieve this by inputting a negative step argument into the `range()` function.

Look at the code below:

Print numbers from -1 to -5, follow these steps:

1. Configure the `for` loop to display decreasing numbers from `-1` to `-5`.
2. Print each number within the loop.

Everything was clear?
