示例1: __init__
def __init__(self, initial_array, delta_t=None, epoch="", dtype=None, copy=True):
if len(initial_array) < 1:
raise ValueError('initial_array must contain at least one sample.')
if delta_t is None:
try:
delta_t = initial_array.delta_t
except AttributeError:
raise TypeError('must provide either an initial_array with a delta_t attribute, or a value for delta_t')
if not delta_t > 0:
raise ValueError('delta_t must be a positive number')
# We gave a nonsensical default value to epoch so we can test if it's been set.
# If the user passes in an initial_array that has an 'epoch' attribute and doesn't
# pass in a value of epoch, then our new object's epoch comes from initial_array.
# But if the user passed in a value---even 'None'---that will take precedence over
# anything set in initial_array. Finally, if the user passes in something without
# an epoch attribute *and* doesn't pass in a value of epoch, it becomes 'None'
