[Why do you give your key file a .py extension? .pem would be better.]

Your key in the next posting (when the broken lines are reconstructed)
seems to be in PKCS1 format. That's what -----BEGIN RSA PUBLIC KEY-----
indicates. However,  M2Crypto.RSA.load_pub_key expects the key in X.509
format, which starts with -----BEGIN PUBLIC KEY----- and also has a
different format inside, so just changing the header and trailer won't
work. 

Anyway, I doubt that the key is correct as it seems to large for just a
public key. How was that key generated?
