I am working on a Python script which opens an excel using win32com and make modification to it.
I am facing an issue while calling objNewRange=objWrkBook.Worksheets('Sheet1').Range('$A$2:$T$15').
I am getting the error :
Run-time error -2147352573: Member not found.
The script works fine when I run it from python shell, but I am calling the same code from HP ALM. I am able to write specifically to a cell using 'Cells' method but it looks like Python is unable to find the Range method.
Below is the Code fragment

I am trying to perform XSLT transform using saxonpy with Python code as attached:
from saxonpy import PySaxonProcessor
import os
class XMLProcessor:
proc = PySaxonProcessor(license = False)
def processXSLT2(self, sourceXmlDocPath, xsltStyleSheetPath):
# https://www.saxonica.com/saxon-c/doc1.2/html/saxonc.html#PyXslt30Processor
print(self.proc.version)
self.proc.set_cwd(os.getcwd()) #set the CWD first
xsltproc = self.proc.new_xslt30_processor()
output = xsltproc.transform_to_string(source_file = sourceXmlDocPath,
stylesheet_file = xsltStyleSheetPath)
return output
In my main py file, it is called using XMLProcessor.processXSLT2(XMLProcessor, LOCAL_XML_FILE, os.environ['LAMBDA_TASK_ROOT'] + '/metadata.xsl')
However, the console shows this error message:
Saxon/C 1.2.1 running with Saxon-HE 9.9.1.5C from Saxonica

this is my first time using pycharm and flask library. i am fairly new to advanced programing and i was trying to create an executable link for my program but im getting a syntax error. when i run the same script in idle without the flask functions and without the if __name__=="__main__": line in python IDLE, it works just as expected.

this is the output I got. I was expecting a link to come which when one visited opens a dialogue box for the tkinter function used
You can't just have a decorator on its own. A decorator needs to state a function.
Your code should be in a function anyway.
(Note though, it makes no sense to try to use tkinter in a Flask app. Why are you using Flask at all here?)
I'm right now trying to code a Maltego tranform to search through the Breach Compilation data, using query.sh
Code:
#!/usr/bin/env python
# Maltego transform for grabbing Breach Compilation results locally.
from MaltegoTransform import *
import sys
import os
import subprocess
email = sys.argv[1]
mt = MaltegoTransform()
try:
dataleak = subprocess.check_output("LOCATION OF QUERY.SH" + email, shell=True).splitlines()
for info in dataleak:
mt.addEntity('maltego.Phrase', info)
else:
mt.addUIMessage("")
except Exception as e:
mt.addUIMessage(str(e))
mt.returnOutput()
Empty value for #org.simpleframework.xml.Text(data=false,
required=true, empty=) on method 'value' in class
com.paterva.maltego.transform.protocol.v2api.messaging.TransformResponse$Notification
at line 26
Not sure what the problem is.
Turns out
else:
mt.addUIMessage("")
except Exception as e:
mt.addUIMessage(str(e))
that bit of code was the problem. Got it working just fine.
So I am new to parallel processing, but I was starting to get it working for parsing multiple Excel files simultaneously. It works well with when I only use openpyxl, but that is a basic XML parser as I understand it. When I include the part that uses XLWings (I like to take advantage of its ability to evaluate equations in Excel for file verification purposes), I get the following error:
pywintypes.com_error: (-2147221008, 'CoInitialize has not been called.', None, None)
This is roughly the code I use to initialize a new XLWings instance and load a workbook:
def openWorkbook(self, filePath):
app = xw.apps.add()
app.display_alerts = False
app.screen_updating = False
wb = self.app.books(filePath) #Note that this is called only once for each workbook.
app.screen_updating = True
app.quit()
Is there some way to get XLWings to open several simultaneous instances of Excel? Should I try doing something like this? If so, I am not sure how the initialization would work with giving threads over to XLWings.
So I figured out the solution, it was actually surprisingly easy. I just added pythoncom.CoInitialize() from pythoncom package before my xw.apps.add() call:
ParallelProcessController.py
from multiprocessing.dummy import Pool
from LoadWorkbook import openWorkbook
def callOpenWorkbookInParallel(self, lsExcelFiles):
pool = Pool(processes=3)
pool.map(openWorkbook, lsExcelFiles)
LoadWorkbook.py
import xlwings as xw
import pythoncom
def openWorkbook(self, filePath):
pythoncom.CoInitialize()
app = xw.apps.add()
wb = app.books(filePath)
app.quit()
I have read many article over the last 6 hours and i still don't understand mocking and unit-testing. I want to unit test a open function, how can i do this correctly?
i am also concerned as the bulk of my code is using external files for data import and manipulation. I understand that i need to mock them for testing, but I am struggling to understand how to move forward.
Some advice please. Thank you in advance

import os
import sys

def openSetupConfig (a):
"""

"""
try:
setupConfig = open(a, "r")
return setupConfig.read()
except Exception as ve:
ve = (str(ve) + "\n\nPlease ensure setup file " + str(a) + " is available")
sys.exit(ve)
dirPath = openSetupConfig("Setup.dat")

So the rule of thumb is to mock, stub or fake all external dependencies to the method/function under test. The point is to test the logic in isolation. So in your case you want to test that it can open a file or log an error message if it can't be opened.
import unittest
from mock import patch
from prototype5 import openSetupConfig # you don't want to run the whole file
import __builtin__ # needed to mock open
def test_openSetupConfig_with_valid_file(self):
"""
It should return file contents when passed a valid file.
"""
expect = 'fake_contents'
with patch('__builtin__.open', return_value=expect) as mock_open:
actual = openSetupConfig("Setup.dat")
self.assertEqual(expect, actual)
mock_open.assert_called()
#patch('prototype5.sys.exit')
def test_openSetupConfig_with_invalid_file(self, mock_exit):
"""
It should log an error and exit when passed an invalid file.
"""
with patch('__builtin__.open', side_effect=FileNotFoundError) as mock_open:
openSetupConfig('foo')
mock_exit.assert_called()
