paramiko installation problem

[D. Xenakis]

>>> import sys
>>> print (sys.path)

returns:

['C:\\Python33\\Lib\\idlelib', 'C:\\Python33\\lib\\site-packages\\pip-1.4-py3.3.egg', 'C:\\Windows\\system32\\python33.zip', 'C:\\Python33\\DLLs', 'C:\\Python33\\lib', 'C:\\Python33', 'C:\\Python33\\lib\\site-packages']

then if i type:
>>> sys.path.append('C:\\Python33\\Lib\\site-packages\\paramiko')

and then again..
>>> print (sys.path)

returns:

['C:\\Python33\\Lib\\idlelib', 'C:\\Python33\\lib\\site-packages\\pip-1.4-py3.3.egg', 'C:\\Windows\\system32\\python33.zip', 'C:\\Python33\\DLLs', 'C:\\Python33\\lib', 'C:\\Python33', 'C:\\Python33\\lib\\site-packages', 'C:\\Python33\\Lib\\site-packages\\paramiko']

then if i type:
>>> import paramiko

i get this:

Traceback (most recent call last):
  File "<pyshell#3>", line 1, in <module>
    import paramiko
  File "C:\Python33\lib\site-packages\paramiko\__init__.py", line 64, in <module>
    from transport import SecurityOptions, Transport
  File "C:\Python33\Lib\site-packages\paramiko\transport.py", line 296
    except socket.error, e:
                       ^
SyntaxError: invalid syntax

----------------------------------------------
when i close and reopen IDLE, then 'C:\\Python33\\Lib\\site-packages\\paramiko' is getting deleted.

If my problem from the first post above has to do something with the path, then what exactly should i do?

I would also like to ask here something extra.. :)

in system enviroment variables my path contains the following things:

C:\Python33\Lib\site-packages\PyQt5;C:\Python33\Scripts\;C:\Python33\;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;C:\Program Files\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Live;C:\Python33\Lib\site-packages\paramiko;C:\Program Files (x86)\Intel\iCLS Client\;C:\Program Files\Intel\iCLS Client\;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files (x86)\Intel\OpenCL SDK\2.0\bin\x86;C:\Program Files (x86)\Intel\OpenCL SDK\2.0\bin\x64;C:\Program Files (x86)\QuickTime\QTSystem\;C:\Program Files\NEST;C:\Program Files (x86)\Windows Live\Shared

so what exactly is the difference between this path and the above.?

A huge THANKS for the one who will find the courage to answer to this newbie !
