Python CSV：读取以逗号终止的行将导致结果为空

忽略每行的最后一个元素：

with open(waveform, 'rb') as f:    reader = csv.reader(f)    for row in reader:        print row[:-1]

或将每一行转换成字典：

columns = ['value']with open(waveform, 'rb') as f:    reader = csv.reader(f)    for row in reader:        rec = dict(zip(columns, row))        print rec
