# Python – Get a sorted list of random integers with unique elements

Given lower and upper limits, generate a sorted list of random numbers with unique elements, starting from start to end.

Examples:

```Input: num = 10, start = 100, end = 200
Output: [102, 118, 124, 131, 140, 148, 161, 166, 176, 180]

Input: num = 5, start = 1, end = 100
Output: [37, 49, 64, 84, 95]
```

To generate random numbers in Python, `randint()` function of `random` module is used.

Syntax:

```randint(start, end)
```

`randint()` accepts two parameters: a starting point and an ending point. Both should be integers and the first value should always be less than the second.

Below is the implementation.

 `# Python program to create  ` `# a sorted list of unique random  ` `# numbers ` ` `  ` `  `import` `random ` ` `  ` `  `# Function to generate a sorted list   ` `# of random numbers in a given ` `# range with unique elements ` `def` `createRandomSortedList(num, start ``=` `1``, end ``=` `100``): ` `    ``arr ``=` `[] ` `    ``tmp ``=` `random.randint(start, end) ` `     `  `    ``for` `x ``in` `range``(num): ` `         `  `        ``while` `tmp ``in` `arr: ` `            ``tmp ``=` `random.randint(start, end) ` `             `  `        ``arr.append(tmp) ` `         `  `    ``arr.sort() ` `     `  `    ``return` `arr ` `  `  `# Driver's code ` `print``(createRandomSortedList(``10``, ``100``, ``200``)) ` `print``(createRandomSortedList(``5``))) `

Output:

```[102, 118, 124, 131, 140, 148, 161, 166, 176, 180]
[37, 49, 64, 84, 95]
```
