Check if it is a vowel(a, e, i, o, u,) on the ```n``` position in a string (the first argument). Don't forget about uppercase.

A few cases:

```
{
checkVowel('cat', 1)  ->   true // 'a' is a vowel
checkVowel('cat', 0)  ->   false // 'c' is not a vowel
checkVowel('cat', 4)  ->   false // this position doesn't exist
}
```
P.S. If n < 0, return false

Solutions:
def check_vowel(s, i):
	return 0 <= i < len(s) and s[i] in 'aieouAEIOU'


def check_vowel(string, position):
	return 0 <= position < len(string) and string[position].lower() in 'aeiou'


def check_vowel(string, position):
	if position < 0:
		return False
	try:
		return string[position].lower() in ['a', 'e', 'i', 'o', 'u']
	except IndexError:
		return False


def check_vowel(s, pos):
	return 0 <= pos < len(s) and s.lower()[pos] in 'aeiou'


def check_vowel(string, position):
	return 0 <= position <= len(string) and string[position] in 'aeiouAEIOU'


def check_vowel(stg, position):
	return 0 <= position < len(stg) and stg[position].lower() in 'aeiou'


def check_vowel(s, i):
	return s[i].lower() in 'aeiou' if len(s) > i > -1 else False


def check_vowel(string, position):
	string = string + '             '
	vowles = ['a', 'e', 'i', 'o', 'u', 'A', 'E', 'I', 'O', 'U']
	if string[position] in vowles:
		return True
	else:
		return False


def check_vowel(string, position):
	if position < 0 or position > len(string):
		return False
	return string[position].lower() in 'aeiou'


def check_vowel(s, t):
	if t == 0 and s[t] in 'aioueAEIOU':
		return True
	return True if t > 0 and t < len(s) and (s[t] in 'aioueAEIOU') else False
	pass
