```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]
```
