以下是将该C++代码转换为Python语言的等效代码：

import os
import socket
import struct

scan_folder = ""
fp = None

class CCallbackImp:
    def __init__(self):
        self.isImageSaved = False
        self.nFrmHeaderLen = 0
        self.pBuffStartAddr = None

    def Process(self, nEventID, pEventParam):
        if nEventID == CR_EVT_NEW_FRAME:
            if self.isImageSaved:
                nBuffIdx = struct.unpack("i", pEventParam.pData)[0]
                ss = scan_folder

                ss += str(pEventParam.nWidth) + "x" + str(pEventParam.nHeight)
                folder = ss
                os.makedirs(folder, exist_ok=True)

                nImgSize = pEventParam.nWidth * pEventParam.nHeight * 2 + self.nFrmHeaderLen

                if self.pBuffStartAddr is not None:
                    pCurrFrame = self.pBuffStartAddr + nBuffIdx * nImgSize

                    nFrameId = struct.unpack("i", pCurrFrame + 8)[0]
                    ss = folder + "\\" + str(nFrameId % 9999).zfill(4) + ".raw"
                    print("frame", nFrameId)
                    PrintMatrix(ss, pCurrFrame[:nImgSize])

def PrintMatrix(filename, data):
    # 实现打印矩阵到文件的逻辑
    pass

# 示例用法
callbackImp = CCallbackImp()
nEventID = CR_EVT_NEW_FRAME
pEventParam = CR_Event()
# 设置pEventParam的属性值
callbackImp.Process(nEventID, pEventParam)

请注意，这只是一个简单的转换示例，并不能保证代码在Python中完全运行。你可能需要根据你的具体需求进行适当的调整和修改。
