def __init__(self, signal):
self.signal = signal
Now, with the requirement that Numeric doesn't inherit from numpy.ndarray, how do I have to extend that definition that Numeric behaves like a numpy.ndarray?
edit: signal should be a np.ndar... |
I have a large text file that reads like
Kyle 40Greg 91Reggie 58

array = ([Kyle, 40], [Greg, 91], [Reggie, 58])

for j in range (0, 10):
new.append(foo)
