In Python, the `range()`

function is a versatile tool for generating numerical sequences efficiently. Let’s explore its functionality, applications, and usage through practical examples.

**Understanding range() Function**

The `range()`

function in Python is used to generate a sequence of numbers. Its syntax is as follows:

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

`start`

: Optional parameter specifying the starting value of the sequence (default is 0).`stop`

: Parameter indicating the ending value of the sequence (exclusive).`step`

: Optional parameter representing the step size (default is 1).

**Example 1: Generating a Sequence**

```
for i in range(5):
print(i, end=' ')
```

**Output 1:**

```
0 1 2 3 4
```

**Example 2: Specifying Start and Stop**

```
for i in range(2, 10):
print(i, end=' ')
```

**Output 2:**

```
2 3 4 5 6 7 8 9
```

**Example 3: Using Step Size**

```
for i in range(1, 10, 2):
print(i, end=' ')
```

**Output 3:**

```
1 3 5 7 9
```

**Example 4: Creating a List**

```
numbers = list(range(5))
print(numbers)
```

**Output 4:**

```
[0, 1, 2, 3, 4]
```

**Points to Remember**

- The
`range()`

function generates numerical sequences efficiently. - It is commonly used in for loops to iterate over a sequence of numbers.
`range()`

supports specifying start, stop, and step parameters to customize the sequence.- Use
`list(range())`

to generate a list based on the range.
