python list数据等间隔抽取并新建list存储的例子

原始数据如下：

['e3cd', 'e547', 'e63d', '0ffd', 'e39b', 'e539', 'e5be', '0dd2', 'e3d6', 'e52e', 'e5f8', '0000', 'e404', 'e52b', 'e63d', '0312', 'e38b']

将其分割为4路数据，分别存储在fetal1、fetal2、mother1、ECG的列表中，各列表对齐，不能整除于4的数据舍去，操作如下：

da = ['e3cd', 'e547', 'e63d', '0ffd', 'e39b', 'e539', 'e5be', '0dd2', 'e3d6', 'e52e', 'e5f8', '0000', 'e404', 'e52b', 'e63d', '0312', 'e38b']
k = 0
num1 = 0
fetal1 = []
fetal2 = []
mother1 = []
ECG = []
for k in range(len(da)-int(len(da) ％ 4)):
 if num1 == 1:
   fetal2.append(da[k])
 elif num1 == 2:
   mother1.append(da[k])
 elif num1 == 3:
   ECG.append(da[k])
 else:
   num1 = 0
   fetal1.append(da[k])
 num1 += 1
print("fetal1:", fetal1)
print("fetal2:", fetal2)
print("mother1", mother1)
print("ECG:", ECG)

运行结果如下：

fetal1: ['e3cd', 'e39b', 'e3d6', 'e404']
fetal2: ['e547', 'e539', 'e52e', 'e52b']
mother1 ['e63d', 'e5be', 'e5f8', 'e63d']
ECG: ['0ffd', '0dd2', '0000', '0312']
