How Do I create a list from numpy array?

How do I get numpy array into python list?

looking for ('foo', 1, 2, 3, 4) series is a numpy array

symbol = 'foo'

def rowp (symbol,series):
            rowp=[]
            series = series[0:4]
            ss = series.tolist     
            rowp.append(symbol)     
            rowp.append(ss)      
            print rowp

I get error:

['foo', <built-in method tolist of numpy.ndarray object at 0x05D07D40>]

As you can already see by the error message, tolist [docs] is a method. That means you have to call it: 

ss = series.tolist()

Update: Use extend instead of append:

rowp.extend(series.tolist())

Btw, the result you get is not an error.
