You've got a bunch of textual data with embedded phone numbers. Write a function `area_code()` that finds and returns just the area code portion of the phone number.
```python
>>> message = "The supplier's phone number is (555) 867-5309"
>>> area_code(message)
'555'
```
The returned area code should be a string, not a number.
Every phone number is formatted like in the example, and the only non-alphanumeric characters in the string are apostrophes `'` or the punctuation used in the phone number.

Solutions:
def area_code(text):
	return text[text.find('(') + 1:text.find(')')]


import re

def area_code(text):
	return re.search('\\((\\d{3})\\)', text).group(1)


def area_code(text):
	return text[text.index('(') + 1:text.index(')')]


def area_code(text):
	area = text.find('(')
	return text[area + 1:area + 4]


def area_code(text):
	return text.split('(')[1].split(')')[0]


def area_code(text):
	parenth1 = text.find('(')
	parenth2 = text.find(')')
	return text[parenth1 + 1:parenth2]


import re

def area_code(message):
	return re.search('\\((\\d{3})\\)', message).group(1)


import re

def area_code(text):
	ac = re.search('\\((\\d{3})\\)\\s\\d{3}\\-\\d{4}', text)
	return ac.group(1)


import re

def area_code(text):
	return re.search('\\((.*)\\)', text).group(1)
