python 从二进制文件中读取浮点数据

import numpy as np

def toDoubleList(dataStr):
    bytesTotal = len(dataStr)

    # 下面的双斜线是除法结果为整数

    # 如果考虑字节序,字节序为big-endian,则以下语句改为  data = struct.unpack('>'+str(bytesTotal/8)+'d',dataStr)
    # 相关匹配格式和字节序请见: https://docs.python.org/zh-cn/3/library/struct.html#struct.calcsize

#### 测试代码

file_bin = "path/to/binfile"
with open(file_bin, 'rb') as f_r:
    dataStr = f_r.read()
    data_vs = toFloat32List(dataStr)
