Question: I am trying to ask for an input of an alphanumeric phone number and convert it to a list so that I can convert the alphabet letters to numbers.

I have this for the input:

```
number=str(input("Enter Alphanumeric phone number:"))
number.split("")

```

and to try and convert it I tried

`number.split("")`

which gave me an error, and 

`list(number)` 

which just left it as a string.

Any ideas on what is going wrong?

Answer: 
You can also use list comprehension for one line input. 
In this method you will not need to write more number of lines.

```
list = [int(i) for i in input()]

```

for input`123456789` you will get `[1,2,3,4,5,6,7,8,9]`
`list(number)` will convert the string to a list of characters. It sounds like you need to assign the result back to `number` though, like this:

```
number = list(number)

```
