You've been collecting change all day, and it's starting to pile up in your pocket, but you're too lazy to see how much you've found.

Good thing you can code!

Create ```change_count()``` to return a dollar amount of how much change you have!

Valid types of change include:
```
penny: 0.01
nickel: 0.05
dime: 0.10
quarter: 0.25
dollar: 1.00
```

```if:python
These amounts are already preloaded as floats into the `CHANGE` dictionary for you to use!
```
```if:ruby
These amounts are already preloaded as floats into the `CHANGE` hash for you to use!
```
```if:javascript
These amounts are already preloaded as floats into the `CHANGE` object for you to use!
```
```if:php
These amounts are already preloaded as floats into the `CHANGE` (a constant) associative array for you to use!
```

You should return the total in the format ```$x.xx```.

Examples:

```python
change_count('nickel penny dime dollar') == '$1.16'
change_count('dollar dollar quarter dime dime') == '$2.45'
change_count('penny') == '$0.01'
change_count('dime') == '$0.10'
```

Warning, some change may amount to over ```$10.00```!

	count = 0
	for coin in change.split():
		count += money[coin]
	result = '%.2f' % count
	return '$' + result

	total = 0
	for i in change.split(' '):
		if i == 'penny':
			total += 0.01
		elif i == 'nickel':
			total += 0.05
		elif i == 'dime':
			total += 0.1
		elif i == 'quarter':
			total += 0.25
		elif i == 'dollar':
			total += 1.0
	return '${:.2f}'.format(total)
print(change_count('dime penny dollar'))
print(change_count('dime penny nickel'))
print(change_count('quarter quarter'))
print(change_count('dollar penny dollar'))


CHANGE = {'penny': 1, 'nickel': 5, 'dime': 10, 'quarter': 25, 'dollar': 100}

	x = round(b + 1e-07, 2)
	a = '$' + '%.2f' % x
	y = a.split()
	if len(y) == 4:
		y.append('0')
		return sum(y)
	else:
		return a

	total = float(0.0)
	ch = ch.split()
