had anyone successfully import and used libpst via python, to extract outlook PST files : http://www.five-ten-sg.com/libpst/ from source package?
It have python bindings but i cannot import after installing (even test.py script comes with it dont work)
Here is Mercurial repo to latest version. Can you guys give a try? i need help..
Actually libpst Python is not well developed , and i had to use from readpst commandline , wrapping inside subprocess call.
So i have to answer this my own.

I am writing a simple script using python to be used on macOS BigSur. I was wondering if there is a way to find the version of an application using python. I know it's possible on Windows using PyWin32 library, however, I could not find anything for MacOS.
Thanks #sudden_appearance for the approach
import os
stream = os.popen('mdls -raw -name kMDItemVersion /Applications/Firefox.app')
targetVer = stream.read()
print(targetVer)
I am trying to get clear concept on how to get the Erwin generated DDL objects with python ? I am aware Erwin API needs to be used. What i am looking if what Python Module and what API needs to used and how to use them ? I would be thankful for some example !
Here is a start:
import win32com.client
ERwin = win32com.client.Dispatch("erwin9.SCAPI")
I haven't been able to browse the scapi dll so what I know is from trial and error. Erwin publishes VB code that works, but it is not straightforward to convert.
Install pywin32 (run the below from pip folder e.g. c:\Program Files\Python37\Scripts)
python -m pip install pywin32
python pywin32_postinstall.py -install
Sample script to extract DDL using Erwin's Forward Engineer functionality (change paths accordingly):
import win32com.client
api = win32com.client.Dispatch("erwin9.SCAPI")
unit = api.PersistenceUnits.Add("c:/models/data_model.erwin", "RDO=Yes")
unit.FEModel_DDL("c:/scripts/ddl_script.sql")
For the above to work, Erwin application should be running (probably).
Iam new bee to the jmeter
My code is working in the Python 2.7 with importing additional packages Dateutil, parser .
Problme : But when I am trying to run same code in the J Meter-JSR-223 PreProcessors , an error saying No module named dateutil in.
So , I have tried another approach to use Jython .
Installed the Jython ( downloaded the dateutil) and provide the packages reference under
import sys
sys.path.append('C:/Jython27/Lib/site-packages')
sys.path.append('C:/Jython27/Lib/site-packages/python_dateutil-2.4.2-py2.7/dateutil')
sys.path.append('C:/Jython27/Lib/site-packages/python_dateutil-2.4.2-py2.7/dateutil')
Now packages error is gone but string syntax error is present .
java.sql.Date' object has no attribute .
I believe dateutil package can be picked up from CPython as it doesn't require any extra wrappers for Java.
Install dateutil normally using pip like:
pip install python-dateutil
Add site-packages folder of Python (not Jython) installation to sys.path like:
sys.path.append("C:\Python27\Lib\site-packages")
That's it, now you should be able to use dateutil module functions from the JSR223 Test Elements:
Be aware that invoking Python scripts via Jython interpreter is not the best idea from performance perspective and if you're about to invoke your Python code only limited number of times and/or with a single thread - it might be better to go for the OS Process Sampler.
If you plan to use the Python code to create the main load - consider using Locust tool instead of JMeter. If you don't want to change JMeter a good approach would be rewriting your Python code in Groovy - it will be way better from the performance perspective.
hi please find follwing
import sys
sys.path.append('C:/Python27/Lib/site-packages')
sys.path.append('C:/Python27/Lib/site-packages/python_dateutil-2.4.2-py2.7/dateutil')
from dateutil.parser import *
sourceDateTimeOfEvent = ""
dateTimeOfEvent = ""
a=parse('2016-07-01 13:00:00')
sourceDateTimeOfEvent = a.isoformat()+"+05:30Z"
dateTimeOfEvent = a.isoformat()+ "Z"
vars.put("sourceDateTimeOfEvent", sourceDateTimeOfEvent)
vars.put("dateTimeOfEvent", dateTimeOfEvent)
This sourceDateTimeOfEvent and dateTimeOfEvent considered as two variables and passed it to the json file
I'm trying to play around with hbase in python and I am using the cloudera repository to install the hadoop/hbase packages. It seems to work as I can access and work on the database using the shell but its not fully working within python.
I know to communicate with hbase I need thrift so I downloaded and complied it from source, I can import thrift into python but when I do from hbase import Hbase, I get module not found errors.
Does anyone know what package/module I would need to get it to work? I tried to look around easy_install and yum(I'm using centos6) and no luck. I did find an article where a person using debain installed it by doing sudo aptiutde install python-hbase I don't have that command/package, so I'm not sure how to get it(or if I have to compile from source to get it).
Also if it helps, I installed most of the base from cloudera and followed some instructions(the ones didn't require install) from http://yannramin.com/2008/07/19/using-facebook-thrift-with-python-and-hbase/
Any help/tips/suggestions would be great.
Thanks!
Have a look at HappyBase (see https://github.com/wbolster/happybase for info). It is the modern way to interact with HBase from Python. It covers the complete Thrift API but wraps it in a much better interface.
Okay, I figured it out. If anyone else is having problems with this in the future its actually pretty easy. In the step where you run thrift --gen py Hbase.thrift, it creates a hbase folder in the location you ran that command. Simply take that command and copy it to your default module folder(or in the folder where you run your program and it should work).
search for /src/contrib/thriftfs/gen-py under hadoop installation folder
Copy the output of thrift --gen py Hbase.thrif onto the location below (part till /home/hadoop/data/ will differ in your case) /home/hadoop/data/hadoop-1.0.4/src/contrib/thriftfs/gen-py
then
$ python
import sys
sys.path.append("/home/hadoop/data/hadoop-1.0.4/src/contrib/thriftfs/gen-py")
import hbase
It should work now
I am using Python 2.6.1 and I want to connect to MySQLdb, I installed mySQL in my system, and I am trying to connect MySQL-python-1.2.2.win32-py2.6 from http://www.codegood.com/archives/4 site but its not working
while running my application its saying that No module named MySQLdb
please any one provide me the proper setup for MySQLdb.
thanks in advance
The best setup for Windows that I've found:
http://www.codegood.com/downloads?dl_cat=2
EDIT: Removed original link (it's an ad farm now :( )
The module is not likely in your python search path..
Check to see if that module is in your Python Path... In windows...you may find it in the registry
HKLM\Software\Python\PythonCore\2.6\PythonPath
Be careful editing it...
You may also alter the Python Path programmaticly by the following
import sys
sys.path.append('somepath_to_the_module_you_wanted')
import the_module_you_wanted
Hope that helps
I was having this problem and then I realised I was importing MySQLdb erroneously - it's case sensitive:
Incorrect: >>>import mysqldb
Correct: >>>import MySQLdb
Silly mistake, but cost me a few hours!
generally, (good) python modules provide a 'setup.py' script that takes care of things like proper installation (google for 'distutils python'). MySQLdb is a "good" module in this sense.
since you're using windows, things might be a bit more complex. I assume you already installed MySQLdb following the instructions and it still gives this problem. what I would do is open a cmd.exe window, cd to the directory containing the 'setup.py' script and there type something like
C:\Python26\Python.exe setup.py install
if this does not work, then grab the module somewhere else, maybe at the place where it is actively developed: http://sourceforge.net/projects/mysql-python/
See this post on the mysql-python blog: MySQL-python-1.2.3 beta 2 released - dated March 2009. Looks like MySQLdb for Python 2.6 is still a work in progress...
I went for compiled binary , thats the best way to go on windows. There is a good source maintained by someone.
I wrote about it here before because some months down the lane I will forget how I solved this and be searching Stack again :/
