Reading objects in generators

Based on my previous question here: How to filter a stream of data

I have encountered an error with the following code:

def alpha_mean(window, alpha):
    cut = alpha//2
    data = sorted(window)[cut:-cut]
    result = sum(data)/len(data)
    return result

def alphatrimmer(window_size, alpha, sensor_stream):
    window = []
    for item in sensor_stream:
        window.append(item)
        if len(window) >= window_size:
            break
    yield alpha_mean(window, alpha)

    for item in sensor_stream:
        window.pop(0)
        window.append(item)
        yield alpha_mean(window,alpha)

The output is a "generator object at 0x00000078' and when I try to iterate it over the generator object, I get an error that float cannot be iterated over. The problem is that I pass the input as floats. How do I fix the issue where floats passed in the generator can be iterated over and printed out? Thank you.
