I'm trying to translate some Java code that uses BouncyCastle  to  Python
using PyCrypto.
Does any one know what the equivalent code in python would be for the
snippet below?

public String getMAC(byte[] macData, byte[] macKey)
    byte[] macBytes = new byte[4];
    CbcBlockCipherMac macCipher = new CbcBlockCipherMac(new DesEdeEngine());

    DesEdeParameters keyParameters = new DesEdeParameters(macKey);
    DesEdeEngine engine = new DesEdeEngine();
    engine.Init(true, keyParameters);

    macCipher.BlockUpdate(macData, 0, macData.Length);
    macCipher.DoFinal(macBytes, 0);
