### Range

In Python, `range`

is a built-in function that is used to generate a sequence of numbers. It is commonly used in `for`

loops to iterate a specific number of times or to create sequences of numbers. The basic syntax of the `range`

function is as follows:

```
range(stop)
range(start, stop)
range(start, stop, step)
```

`start`

(optional): The starting value of the sequence. If not specified, it defaults to`0`

.`stop`

: The exclusive upper limit of the sequence. The sequence will stop before reaching this value.`step`

(optional): The step or the difference between each number in the sequence. If not specified, it defaults to`1`

.

Here are a few examples to illustrate the usage of the `range`

function:

__Using__`range`

with a Stop Value:for i in range(5): print(i)Output:

In this example,

`range(5)`

generates a sequence of numbers from`0`

to`4`

.__Using__`range`

with Start and Stop Values:for i in range(2, 8): print(i)Output:

2 3 4 5 6 7Here,

`range(2, 8)`

generates a sequence from`2`

to`7`

.__Using__`range`

with Start, Stop, and Step Values:for i in range(1, 10, 2): print(i)Output:

In this case,

`range(1, 10, 2)`

generates a sequence with a step of`2`

between numbers.__Creating a List with__`range`

:numbers = list(range(3, 15, 3)) print(numbers)Output:

[3, 6, 9, 12]Here,

`range(3, 15, 3)`

is used to create a list of numbers with a step of`3`

.

The `range`

function is useful when you need to iterate over a sequence of numbers or when you want to create a list of numbers with a specific pattern. Keep in mind that the `range`

function does not create a list directly; it produces a range object. If you need a list, you can convert it using the `list()`

constructor, as shown in the last example.
