How clean the code up so usage is

ema(x, 5) returns the data now in emaout. Im trying to enclose everything in one def.

ex:

def ema(series, period):
   return ema

Right now its in a for loop and a def. and would work with numpy array.

x = [32.47, 32.70, 32.77, 33.11, 33.25, 33.23, 33.23, 33.0, 33.04, 33.21]

def ema(series, period, prevma):
    smoothing = 2.0 / (period + 1.0)                
    return prevma + smoothing * (series[bar] - prevma)

prevema = x[0] 
emaout =[]

for bar, close in enumerate(x):
    curema = ema(x, 5, prevema) 
    prevema = curema
    emaout.append(curema)

print 
print emaout  

How can I rework the code up that ema(x, 5) returns the data now in emaout? I'm trying to enclose everything in one def.

Right now its in a for loop and a def.

x = [32.47, 32.70, 32.77, 33.11, 33.25, 33.23, 33.23, 33.0, 33.04, 33.21]

def ema(series, period, prevma):
    smoothing = 2.0 / (period + 1.0)                
    return prevma + smoothing * (series[bar] - prevma)

prevema = x[0] 
emaout =[]

for bar, close in enumerate(x):
    curema = ema(x, 5, prevema) 
    prevema = curema
    emaout.append(curema)

print 
print emaout

x could be a NumPy array.
