I've got a script that is intended to sort my photo/video collection (Windows). The photos work fine as they are sortable by EXIF which is easily accessed.
Videos are harder because I have to get the file's "Media Creation Date" which is readable by only pywin32, to my understanding. However, once I've accessed the media creation date, shutil.move() does not work. It throws no error, it just runs indefinitely without progress until I manually kill the script:
Here's the snippet in question:
from datetime import datetime
import exifread
import os
from pathlib import Path
import shutil
from win32com.propsys import propsys, pscon
# get the file list, do stuff with photos, etc
# f is the file
# cr is the path root to which it will be moved
elif str(f).lower().endswith(("mp4", "mov")):
props = propsys.SHGetPropertyStoreFromParsingName(f)
dt = props.GetValue(pscon.PKEY_Media_DateEncoded).GetValue()
year, month = str(dt.year), str(dt.month).zfill(2)
new_fn = dt.strftime("%Y-%m-%d_%H%M%S")
new_fn = f"{new_fn}{os.path.splitext(f)[1]}"
move_path = os.path.join(cr, year, month, new_fn)
print(f"SRC: {f}")
print(f"DESTINATION: {move_path}")
print("----------------------------------")
shutil.move(f, move_path)
It prints the source correctly, and the destination correctly, but does not move the file. I have also tried os.rename() and os.replace() with the same result, which suggests that perhaps the propsys method still has a lock on the file? How do I free up this file for moving?
Yes, propsys is blocking the file (you can check in Process Explorer), try just deleting it:
fpath = r'c:\temp\user\t\test.mp4'
move_path = r'c:\temp\user\t\test moved.mp4'
props = propsys.SHGetPropertyStoreFromParsingName(fpath)
print( props.GetValue(pscon.PKEY_Media_DateEncoded).GetValue() )
del props
shutil.move(fpath , move_path)
I'am tasked with converting tons of .doc files to .pdf. And the only way my supervisor wants me to do this is through MSWord 2010. I know I should be able to automate this with python COM automation. Only problem is I dont know how and where to start. I tried searching for some tutorials but was not able to find any (May be I might have, but I don't know what I'm looking for).
Right now I'm reading through this. Dont know how useful this is going to be.
A simple example using comtypes, converting a single file, input and output filenames given as commandline arguments:
import sys
import os
import comtypes.client
wdFormatPDF = 17
in_file = os.path.abspath(sys.argv[1])
out_file = os.path.abspath(sys.argv[2])
word = comtypes.client.CreateObject('Word.Application')
doc = word.Documents.Open(in_file)
doc.SaveAs(out_file, FileFormat=wdFormatPDF)
doc.Close()
word.Quit()
You could also use pywin32, which would be the same except for:
import win32com.client
and then:
word = win32com.client.Dispatch('Word.Application')
You can use the docx2pdf python package to bulk convert docx to pdf. It can be used as both a CLI and a python library. It requires Microsoft Office to be installed and uses COM on Windows and AppleScript (JXA) on macOS.
from docx2pdf import convert
convert("input.docx")
convert("input.docx", "output.pdf")
convert("my_docx_folder/")
pip install docx2pdf
docx2pdf input.docx output.pdf
Disclaimer: I wrote the docx2pdf package. https://github.com/AlJohri/docx2pdf
I have tested many solutions but no one of them works efficiently on Linux distribution.
I recommend this solution :
import sys
import subprocess
import re
def convert_to(folder, source, timeout=None):
args = [libreoffice_exec(), '--headless', '--convert-to', 'pdf', '--outdir', folder, source]
process = subprocess.run(args, stdout=subprocess.PIPE, stderr=subprocess.PIPE, timeout=timeout)
filename = re.search('-> (.*?) using filter', process.stdout.decode())
return filename.group(1)
def libreoffice_exec():
# TODO: Provide support for more platforms
if sys.platform == 'darwin':
return '/Applications/LibreOffice.app/Contents/MacOS/soffice'
return 'libreoffice'
and you call your function:
result = convert_to('TEMP Directory', 'Your File', timeout=15)

I have worked on this problem for half a day, so I think I should share some of my experience on this matter. Steven's answer is right, but it will fail on my computer. There are two key points to fix it here:
(1). The first time when I created the 'Word.Application' object, I should make it (the word app) visible before open any documents. (Actually, even I myself cannot explain why this works. If I do not do this on my computer, the program will crash when I try to open a document in the invisible model, then the 'Word.Application' object will be deleted by OS. )
(2). After doing (1), the program will work well sometimes but may fail often. The crash error "COMError: (-2147418111, 'Call was rejected by callee.', (None, None, None, 0, None))" means that the COM Server may not be able to response so quickly. So I add a delay before I tried to open a document.
After doing these two steps, the program will work perfectly with no failure anymore. The demo code is as below. If you have encountered the same problems, try to follow these two steps. Hope it helps.
import os
import comtypes.client
import time
wdFormatPDF = 17
# absolute path is needed
# be careful about the slash '\', use '\\' or '/' or raw string r"..."
in_file=r'absolute path of input docx file 1'
out_file=r'absolute path of output pdf file 1'
in_file2=r'absolute path of input docx file 2'
out_file2=r'absolute path of outputpdf file 2'
# print out filenames
print in_file
print out_file
print in_file2
print out_file2
# create COM object
word = comtypes.client.CreateObject('Word.Application')
# key point 1: make word visible before open a new document
word.Visible = True
# key point 2: wait for the COM Server to prepare well.
time.sleep(3)
# convert docx file 1 to pdf file 1
doc=word.Documents.Open(in_file) # open docx file 1
doc.SaveAs(out_file, FileFormat=wdFormatPDF) # conversion
doc.Close() # close docx file 1
word.Visible = False
# convert docx file 2 to pdf file 2
doc = word.Documents.Open(in_file2) # open docx file 2
doc.SaveAs(out_file2, FileFormat=wdFormatPDF) # conversion
doc.Close() # close docx file 2
word.Quit() # close Word Application

Works very nicely for doc, docx, ppt, pptx, xls, xlsx.
Very useful if you need to convert docs or save/convert to certain formats on a server.
As an alternative to the SaveAs function, you could also use ExportAsFixedFormat which gives you access to the PDF options dialog you would normally see in Word. With this you can specify bookmarks and other document properties.
doc.ExportAsFixedFormat(OutputFileName=pdf_file,
ExportFormat=17, #17 = PDF output, 18=XPS output
OpenAfterExport=False,
OptimizeFor=0, #0=Print (higher res), 1=Screen (lower res)
CreateBookmarks=1, #0=No bookmarks, 1=Heading bookmarks only, 2=bookmarks match word bookmarks
DocStructureTags=True
);
The full list of function arguments is: 'OutputFileName', 'ExportFormat', 'OpenAfterExport', 'OptimizeFor', 'Range', 'From', 'To', 'Item', 'IncludeDocProps', 'KeepIRM', 'CreateBookmarks', 'DocStructureTags', 'BitmapMissingFonts', 'UseISO19005_1', 'FixedFormatExtClassPtr'
It's worth noting that Stevens answer works, but make sure if using a for loop to export multiple files to place the ClientObject or Dispatch statements before the loop - it only needs to be created once - see my problem: Python win32com.client.Dispatch looping through Word documents and export to PDF; fails when next loop occurs
If you don't mind using PowerShell have a look at this Hey, Scripting Guy! article. The code presented could be adopted to use the wdFormatPDF enumeration value of WdSaveFormat (see here).
This blog article presents a different implementation of the same idea.
I have modified it for ppt support as well. My solution support all the below-specified extensions.
word_extensions = [".doc", ".odt", ".rtf", ".docx", ".dotm", ".docm"]
ppt_extensions = [".ppt", ".pptx"]

I have modified code from Docx2PDF
I tried the accepted answer but wasn't particularly keen on the bloated PDFs Word was producing which was usually an order of magnitude bigger than expected. After looking how to disable the dialogs when using a virtual PDF printer I came across Bullzip PDF Printer and I've been rather impressed with its features. It's now replaced the other virtual printers I used previously. You'll find a "free community edition" on their download page.
The COM API can be found here and a list of the usable settings can be found here. The settings are written to a "runonce" file which is used for one print job only and then removed automatically. When printing multiple PDFs we need to make sure one print job completes before starting another to ensure the settings are used correctly for each file.
import os, re, time, datetime, win32com.client
def print_to_Bullzip(file):
util = win32com.client.Dispatch("Bullzip.PDFUtil")
settings = win32com.client.Dispatch("Bullzip.PDFSettings")
settings.PrinterName = util.DefaultPrinterName # make sure we're controlling the right PDF printer
outputFile = re.sub("\.[^.]+$", ".pdf", file)
statusFile = re.sub("\.[^.]+$", ".status", file)
settings.SetValue("Output", outputFile)
settings.SetValue("ConfirmOverwrite", "no")
settings.SetValue("ShowSaveAS", "never")
settings.SetValue("ShowSettings", "never")
settings.SetValue("ShowPDF", "no")
settings.SetValue("ShowProgress", "no")
settings.SetValue("ShowProgressFinished", "no") # disable balloon tip
settings.SetValue("StatusFile", statusFile) # created after print job
settings.WriteSettings(True) # write settings to the runonce.ini
util.PrintFile(file, util.DefaultPrinterName) # send to Bullzip virtual printer
# wait until print job completes before continuing
# otherwise settings for the next job may not be used
timestamp = datetime.datetime.now()
while( (datetime.datetime.now() - timestamp).seconds < 10):
if os.path.exists(statusFile) and os.path.isfile(statusFile):
error = util.ReadIniString(statusFile, "Status", "Errors", '')
if error != "0":
raise IOError("PDF was created with errors")
os.remove(statusFile)
return
time.sleep(0.1)
raise IOError("PDF creation timed out")
I was working with this solution but I needed to search all .docx, .dotm, .docm, .odt, .doc or .rtf and then turn them all to .pdf (python 3.7.5). Hope it works...
import os
import win32com.client
wdFormatPDF = 17
for root, dirs, files in os.walk(r'your directory here'):
for f in files:
if f.endswith(".doc") or f.endswith(".odt") or f.endswith(".rtf"):
try:
print(f)
in_file=os.path.join(root,f)
word = win32com.client.Dispatch('Word.Application')
word.Visible = False
doc = word.Documents.Open(in_file)
doc.SaveAs(os.path.join(root,f[:-4]), FileFormat=wdFormatPDF)
doc.Close()
word.Quit()
word.Visible = True
print ('done')
os.remove(os.path.join(root,f))
pass
except:
print('could not open')
# os.remove(os.path.join(root,f))
elif f.endswith(".docx") or f.endswith(".dotm") or f.endswith(".docm"):
try:
print(f)
in_file=os.path.join(root,f)
word = win32com.client.Dispatch('Word.Application')
word.Visible = False
doc = word.Documents.Open(in_file)
doc.SaveAs(os.path.join(root,f[:-5]), FileFormat=wdFormatPDF)
doc.Close()
word.Quit()
word.Visible = True
print ('done')
os.remove(os.path.join(root,f))
pass
except:
print('could not open')
# os.remove(os.path.join(root,f))
else:
pass
The try and except was for those documents I couldn't read and won't exit the code until the last document.
You should start from investigating so called virtual PDF print drivers.
As soon as you will find one you should be able to write batch file that prints your DOC files into PDF files. You probably can do this in Python too (setup printer driver output and issue document/print command in MSWord, later can be done using command line AFAIR).
import docx2txt
from win32com import client
import os
files_from_folder = r"c:\\doc"
directory = os.fsencode(files_from_folder)
amount = 1
word = client.DispatchEx("Word.Application")
word.Visible = True
for file in os.listdir(directory):
filename = os.fsdecode(file)
print(filename)
if filename.endswith('docx'):
text = docx2txt.process(os.path.join(files_from_folder, filename))
print(f'{filename} transfered ({amount})')
amount += 1
new_filename = filename.split('.')[0] + '.txt'
try:
with open(os.path.join(files_from_folder + r'\txt_files', new_filename), 'w', encoding='utf-8') as t:
t.write(text)
except:
os.mkdir(files_from_folder + r'\txt_files')
with open(os.path.join(files_from_folder + r'\txt_files', new_filename), 'w', encoding='utf-8') as t:
t.write(text)
elif filename.endswith('doc'):
doc = word.Documents.Open(os.path.join(files_from_folder, filename))
text = doc.Range().Text
doc.Close()
print(f'{filename} transfered ({amount})')
amount += 1
new_filename = filename.split('.')[0] + '.txt'
try:
with open(os.path.join(files_from_folder + r'\txt_files', new_filename), 'w', encoding='utf-8') as t:
t.write(text)
except:
os.mkdir(files_from_folder + r'\txt_files')
with open(os.path.join(files_from_folder + r'\txt_files', new_filename), 'w', encoding='utf-8') as t:
t.write(text)
word.Quit()

I would suggest ignoring your supervisor and use OpenOffice which has a Python api. OpenOffice has built in support for Python and someone created a library specific for this purpose (PyODConverter).
If he isn't happy with the output, tell him it could take you weeks to do it with word.
So, I'll explain briefly my idea, then, what I've tried and errors that I've got so far.
I want to make a Python script that will:
Search for files in a directory, example: /home/mystuff/logs
If he found it, he will execute a command like print('Errors found'), and then stop.
If not, he will keep it executing on and on.
But other logs will be there, so, my intention is to make Python read logs in /home/mystuff/logs filtering by the current date/time only.. since I want it to be executed every 2 minutes.
Here is my code:
import time
import os
from time import sleep
infile = r"/home/mystuff/logs`date +%Y-%m-%d`*"
keep_phrases = ["Error",
"Lost Connection"]
while True:
with open(infile) as f:
f = f.readlines()
if phrase in f:
cmd = ['#print something']
erro = 1
else:
sleep(1)
I've searched for few regex cases for current date, but nothing related to files that will keep changing names according by the date/time.. do you have any ideas?
You can't use shell features like command substitutions in file names. To the OS, and to Python, a file name is just a string. But you can easily create a string which contains the current date and time.
from datetime import datetime
infile = r"/home/mystuff/logs%s" % datetime.now().strftime('%Y-%m-%d')
(The raw string doesn't do anything useful, because the string doesn't contain any backslashes. But it's harmless, so I left it in.)
You also can't open a wildcard; but you can expand it to a list of actual file names with glob.glob(), and loop over the result.
from glob import glob
for file in glob(infile + '*'):
with open(file, 'r') as f:
# ...
If you are using a while True: loop you need to calculate today's date inside the loop; otherwise you will be perpetually checking for files from the time when the script was started.
In summary, your changed script could look something like this. I have changed the infile variable name here because it isn't actually a file or a file name, and fixed a few other errors in your code.
# Unused imports
# import time
# import os
from datetime import datetime
from glob import glob
from time import sleep
keep_phrases = ["Error",
"Lost Connection"]
while True:
pattern = "/home/mystuff/logs%s*" % datetime.now().strftime('%Y-%m-%d')
for file in glob(pattern):
with open(file) as f:
for line in f:
if any(phrase in line for phrase in keep_phrases):
cmd = ['#print something']
erro = 1
break
sleep(120)
I am writing some code that will go through a file, edit it as a temp file, and than copy the temp file over the new file so as to make the edit. However when using the move method from shutil I keep getting this error :
IOError: [Errno 22] Invalid Argument
I've tried using copy, copy2, and copyfile. Here is a copy of the code :
def writePPS(seekValue,newData):
PPSFiles = findPPS("/pps")
for file in PPSFiles:
#create a temp file
holder,temp = mkstemp(".pps")
print holder, temp
pps = open(file,"r+")
newpps = open(temp,"w")
info = pps.readlines()
#parse through the pps file and find seekvalue, replace with newdata
for data in info:
valueBoundry = data.find(":")
if seekValue == data[0:(valueBoundry)]:
print "writing new value"
newValue = data[0:(valueBoundry+1)] + str(newData)
#write to our temp file
newpps.write(newValue)
else: newpps.write(data)
pps.close()
close(holder)
newpps.close()
#remove original file
remove(file)
#move temp file to pps
copy(temp,"/pps/ohm.pps")
I am not exactly sure why you are getting that error, but to start you could try cleaning up your code a bit and fixing all those import statements. Its hard to see where the functions are coming from and for all you know you could have a namespace collision eventually.
Lets start here with some actually runnable code:
import shutil
import os
import tempfile
def writePPS(seekValue,newData):
PPSFiles = findPPS("/pps")
for file_ in PPSFiles:
#create a temp file
newpps = tempfile.NamedTemporaryFile(suffix=".pps")
print newpps.name
with open(file_,"r+") as pps:
#parse through the pps file and find seekvalue, replace with newdata
for data in pps:
valueBoundry = data.find(":")
if seekValue == data[0:(valueBoundry)]:
print "writing new value"
newValue = data[0:(valueBoundry+1)] + str(newData)
#write to our temp file
newpps.write(newValue)
else:
newpps.write(data)
#move temp file to pps
newpps.flush()
shutil.copy(newpps.name,"/pps/ohm.pps")
You don't need to read all your lines into memory. You can just loop over each line. You also don't need to manage all those open/close file operations. Just use a with context and also a NamedTemporaryFile which will clean itself up when it is garbage collected.
Important note, that in your example and above, you are overwriting the same destination file each time for every source file. I left it that way for you to address. But if you start here, we can then begin to figure out why you are getting errors.
