I am trying to get a list input by the user and then sort the list elements (which are integers) in ascending order. But the elements are stored as strings and I don't know how to convert each element into `int` type. For example:

```
p = input("Enter comma separated numbers:")
p = p.split(",")
p.sort()
print(p)

```

When I input

```
-9,-3,-1,-100,-4

```

I get the result as:

```
['-1', '-100', '-3', '-4', '-9']

```

But the desired output is:

```
[-100, -9, -4, -3, -1]

```
