Welcome.

In this kata you are required to, given a string, replace every letter with its position in the alphabet.

If anything in the text isn't a letter, ignore it and don't return it.

`"a" = 1`, `"b" = 2`, etc.

## Example

```python
alphabet_position("The sunset sets at twelve o' clock.")
```
Should return `"20 8 5 19 21 14 19 5 20 19 5 20 19 1 20 20 23 5 12 22 5 15 3 12 15 3 11"` (as a string)

Solutions:
def alphabet_position(text):
	return ' '.join((str(ord(c) - 96) for c in text.lower() if c.isalpha()))


def alphabet_position(s):
	return ' '.join((str(ord(c) - ord('a') + 1) for c in s.lower() if c.isalpha()))


alphabet = 'abcdefghijklmnopqrstuvwxyz'

def alphabet_position(text):
	if type(text) == str:
		text = text.lower()
		result = ''
		for letter in text:
			if letter.isalpha() == True:
				result = result + ' ' + str(alphabet.index(letter) + 1)
		return result.lstrip(' ')
