How to import OpenSSL in python

Question

I am trying to run this simple code to retrieve SSL certificate:

import ssl, socket

#print ssl.get_server_certificate(('www.google.com', 443))
cert=ssl.get_server_certificate(('www.google.com', 443))
# OpenSSL
x509 = OpenSSL.crypto.load_certificate(OpenSSL.crypto.FILETYPE_PEM, cert)
x509.get_subject().get_components()

But I get error saying:

Traceback (most recent call last):
  File "C:\Users\e\Desktop\Python\ssl\test.py", line 6, in <module>
    x509 = OpenSSL.crypto.load_certificate(OpenSSL.crypto.FILETYPE_PEM, cert)
NameError: name 'OpenSSL' is not defined

I am aware that I have to import OpenSSL. But I do not know how? and where to get the OpenSSL from? I downloaded a module called pyOpenSSL from https://pypi.python.org/pypi/pyOpenSSL Which contains two folders: pyOpenSSL-0.15.1.dist-info and OpenSSL. When I tried to add import OpenSSL or import pyOpenSSL I get errors. Can you explain clearly please, how to import these libraries or modules? where they should be placed? if not in the same directory of my code file? how to write the path in the import syntax?? Please, help.

EDIT: when tried to add from OpenSSL import SSL in the code, I got:

    C:\Users\e\Desktop\Python\ssl>test.py
Traceback (most recent call last):
  File "C:\Users\e\Desktop\Python\ssl\test.py", line 2, in <module>
    from OpenSSL import SSL
  File "C:\Users\e\Desktop\Python\ssl\OpenSSL\__init__.py", line 8, in <module>
    from OpenSSL import rand, crypto, SSL
  File "C:\Users\e\Desktop\Python\ssl\OpenSSL\rand.py", line 9, in <module>
    from six import integer_types as _integer_types
ImportError: No module named six

pip install six or pip install requests[security] – Padraic Cunningham Jun 02 '15 at 18:37 — Padraic Cunningham, Jun 02 '15 at 18:37

From the tests:

from OpenSSL import SSL

Response to the edit: pip install pyopenssl should have installed six. If you're trying to install yourself, I'd not do this, but you can install the dependencies manually using pip install six cryptography and then your import should work fine. If not, leave a comment and I'll do some further investigation.

Response to comment: There are instructions on installing pip on windows.

I am a windows user. I tried the command but I get: " 'pip' is not recognized as an internal or external command, operable program or batch file." – user2192774 Jun 02 '15 at 19:24
@user2192774, please type 'python -m pip install pyopenssl'. – lcieslak Aug 23 '19 at 08:23
