A currency formatter written in Python.

currency_formatter.py

# all num is converted into float
def currency_format(num):
	sol = str(float(num)).split(".")
	sol[0] = sol[0][::-1]
	final = ""
	while len(sol[0]):
		sol_r_e = sol[0][:3]#slice (get 3 characters)
		sol[0] = sol[0][3:]#slice (decrease)
		if len(sol_r_e) == 3 and not len(sol[0]) == 0:sol_r_e += ","
		final += sol_r_e
	return "P {0}.{1}".format(final[::-1], sol[1])

def currency_unformat(cur):
	price=cur.split()
	if len(price) == 2:
		return price[1].replace(",","")
	elif len(price) == 1:
		return price[0].replace(",","")
	else:
		return ""
	
print(currency_format(1234.20))
print(currency_unformat(currency_format(1234.20)))

'''
outputs:
>> $ 1,234.2
>> 1234.2

The reason for doing this is that I couldn't find any solution online, that's working on python verson 2.6 and below.
