Here is the code that i used

import M2Crypto
from M2Crypto import RSA

def encrypt():
    recip = M2Crypto.RSA.load_pub_key(open
('recipient_public_key.pem','rb').read())
    #recip = M2Crypto.RSA.load_pub_key('recipient_public_key.pem')
    print recip;
    plaintext =" whatever i need to encrypt"
    msg = recip.public_encrypt(plaintext,RSA.pkcs1_padding)
    print msg;


    encrypt()


error coming like - IOError: [Errno 2] No such file or directory:
'recipient_public_key.pem'

Is this not the inbuilt file.
How should i create such type of file.
