I am running the following block of code to create the path to a new file:
# Opens/create the file that will be created
device_name = target_device["host"].split('.')
path = "/home/user/test_scripts/configs/" + device_name[-1] + "/"
print(path)
# Check if path exists
if not os.path.exists(path):
os.makedirs(path)
# file = open(time_now + "_" + target_device["host"] + "_config.txt", "w")
file = open(path + time_now + "_" + device_name[0] + "_config.txt", "w")
# Time Stamp File
file.write('\n Create on ' + now.strftime("%Y-%m-%d") +
' at ' + now.strftime("%H:%M:%S") + ' GMT\n')
# Writes output to file
file.write(output)
# Close file
file.close()
The code run as intended with the exception that it creates and saves the files on the directory: /home/user/test_scripts/configs/ instead on the indented one that should be: /home/user/test_scripts/configs/device_name[-1]/.
Please advise.

Try using os.path.join(base_path, new_path) [Reference] instead of string concatenation. For example:
path = os.path.join("/home/user/test_scripts/configs/", device_name[-1])
os.makedirs(path, exist_ok=True)
new_name = time_now + "_" + device_name[0] + "_config.txt"
with open(os.path.join(path, new_name), "w+") as file:
file.write("something")
Although I don't get why you're creating a directory with device_name[-1] and as a file name using device_name[0].

I tried to generate a file named, for example, 23-10-2022|21-03-11.xml or if the user enters his own name userGeneratedName23-10-2022-21-03-11.xml. I don't know why when I tried to specify a particular folder where the generated file should be saved the program throws me an Invalid argument error. I suspect that I am using join incorrectly, I don't really know how to correct it

I have python script which synchronizes files from the remote server by comparing with the local files. It uses a file downloading tool written injava. I store filepath, file size and its name in dictionary which looks like:
eddsFilesDict = {'/part07_data07/Science/TGO/ACS/SDU_': ['860904
SDU__DACS_51FC_023D8101_2021-155T02-12-17__00001.EXM', '17660866
SDU__DACS_51FB_023D8101_2021-155T02-10-16__00001.EXM', '17660866
SDU__DACS_51FA_023D8101_2021-155T 02-02-18__00001.EXM', '17660866
SDU__DACS_51F9_023D8101_2021-155T02-00-16__00001.EXM']}
To list up files on the local machine I use next part of the code:
filenames = []
for top, dirs, files in os.walk('/data/local/'):
for fn in files:
filenames.append(os.stat(os.path.join(top, fn)).st_size.__str__() + ' ' + os.path.join(fn))
But in the following part of my script usage of CPU goes up to 100% and it lasts for 1-2 minutes. I cannot understand why. By experimental way I understood that subprocess is not the thing.
for pathname, fileName in eddsFilesDict.items():
for f in fileName:
if f not in filenames:
logger.info('REQUESTING FILE: ' + pathname + '/' + f.split('.')[0].split(' ')[1] + ' FILE SIZE: '
+ f.split(' ')[0])
if 'SDU' in f:
argsFile = shlex.split(
'/home/user1/client/bin/fs_client --arc tar') # here I call java tool to start file downloading
p1 = subprocess.Popen(argsFile, stderr=subprocess.PIPE)
out, err = p1.communicate()
logger.warning('REQUESTING FILE: ' + pathname + '/' + f.split('.')[0].split(' ')[1] + ' FILE SIZE: '
+ f.split(' ')[0] + '\n' + err.__str__())
elif 'SCI' in f:
argsFile = shlex.split(
'/home/user1/client/bin/fs_client --arc tar')
p2 = subprocess.Popen(argsFile, stderr=subprocess.PIPE)
out, err = p2.communicate()
logger.warning('REQUESTING FILE: ' + pathname + '/' + f.split('.')[0].split(' ')[1] + ' FILE SIZE: '
+ f.split(' ')[0] + '\n' + err.__str__())
I have a requirement to get the file details for certain locations (within the system and SFTP) and get the file size for some locations on SFTP which can be achieved using the shared code.
def getFileDetails(location: str):
filenames: list = []
if location.find(":") != -1:
for file in glob.glob(location):
filenames.append(getFileNameFromFilePath(file))
else:
with pysftp.Connection(host=myHostname, username=myUsername, password=myPassword) as sftp:
remote_files = [x.filename for x in sorted(sftp.listdir_attr(location), key=lambda f: f.st_mtime)]
if location == LOCATION_SFTP_A:
for filename in remote_files:
filenames.append(filename)
sftp_archive_d_size_mapping[filename] = sftp.stat(location + "/" + filename).st_size
elif location == LOCATION_SFTP_B:
for filename in remote_files:
filenames.append(filename)
sftp_archive_e_size_mapping[filename] = sftp.stat(location + "/" + filename).st_size
else:
for filename in remote_files:
filenames.append(filename)
sftp.close()
return filenames
There are more than 10000+ files in LOCATION_SFTP_A and LOCATION_SFTP_B. For each file, I need to get the file size. To get the size I am using
sftp_archive_d_size_mapping[filename] = sftp.stat(location + "/" + filename).st_size
sftp_archive_e_size_mapping[filename] = sftp.stat(location + "/" + filename).st_size
# Time Taken : 5 min+
sftp_archive_d_size_mapping[filename] = 1 #sftp.stat(location + "/" + filename).st_size
sftp_archive_e_size_mapping[filename] = 1 #sftp.stat(location + "/" + filename).st_size
# Time Taken : 20-30 s
If I comment sftp.stat(location + "/" + filename).st_size and assign static value It takes only 20-30 seconds to run the entire code. I am looking for a way How can optimize the time and get the file size details.
The Connection.listdir_attr already gives you the file size in SFTPAttributes.st_size.
There's no need to call Connection.stat for each file to get the size (again).

I have a large folder having 900+ sub-folders, each of which has another folder inside it which in turn has a zipped file.
Its like -
-MyFolder
-----MySubfolder
---------MySubSubfolder
-------------MyFile.zip
How can I decompress all the zipped files in their respective folder OR in a separate folder elsewhere in Windows using Python?
Any help would be great!!
You could try something like:
import zipfile,os;
def unzip(source_filename, dest_dir):
with zipfile.ZipFile(source_filename) as zf:
for member in zf.infolist():
extract_allowed = True;
path = dest_dir;
words = member.filename.split('/');
for word in words:
if (word == '..'):
extract_allowed = False;
break;
if (extract_allowed == True):
zf.extract(member, dest_dir);
def unzipFiles(dest_dir):
for file in os.listdir(dest_dir):
if (os.path.isdir(dest_dir + '/' + file)):
return unzipFiles(dest_dir + '/' + file);
if file.endswith(".zip"):
print 'Found file: "' + file + '" in "' + dest_dir + '" - extracting';
unzip(dest_dir + '/' + file, dest_dir + '/');
unzipFiles('./MyFolder');
I am trying to:
Loop through a bunch of files
makes some changes
Copy the old file to a sub directory. Here's the kicker I don't want to overwrite the file in the new directory if it already exists. (e.g. if "Filename.mxd" already exists, then copy and rename to "Filename_1.mxd". If "Filename_1.mxd" exists, then copy the file as "Filename_2.mxd" and so on...)
save the file (but do a save, not a save as so that it overwrites the existing file)
it goes something like this:
for filename in glob.glob(os.path.join(folderPath, "*.mxd")):
fullpath = os.path.join(folderPath, filename)
mxd = arcpy.mapping.MapDocument(filename)
if os.path.isfile(fullpath):
basename, filename2 = os.path.split(fullpath)
# Make some changes to my file here
# Copy the in memory file to a new location. If the file name already exists, then rename the file with the next instance of i (e.g. filename + "_" + i)
for i in range(50):
if i > 0:
print "Test1"
if arcpy.Exists(draftloc + "\\" + filename2) or arcpy.Exists(draftloc + "\\" + shortname + "_" + str(i) + extension):
print "Test2"
pass
else:
print "Test3"
arcpy.Copy_management(filename2, draftloc + "\\" + shortname + "_" + str(i) + extension)
mxd.save()
So, 2 things I decided to do, was to just set the range of files well beyond what I expect to ever occur (50). I'm sure there's a better way of doing this, by just incrementing to the next number without setting a range.
The second thing, as you may see, is that the script saves everything in the range. I just want to save it once on the next instance of i that does not occur.
Hope this makes sense,
Mike
Use a while loop instead of a for loop. Use the while loop to find the appropriate i, and then save afterwards.
The code/pseudocode would look like:
result_name = original name
i = 0
while arcpy.Exists(result_name):
i+=1
result_name = draftloc + "\\" + shortname + "_" + str(i) + extension
save as result_name
This should fix both issues.
thanks to Maty suggestion above, I've come up with my answer. For those who are interested, my code is:
result_name = filename2
print result_name
i = 0
# Check if file exists
if arcpy.Exists(draftloc + "\\" + result_name):
# If it does, increment i by 1
i+=1
# While each successive filename (including i) does not exists, then save the next filename
while not arcpy.Exists(draftloc + "\\" + shortname + "_" + str(i) + extension):
mxd.saveACopy(draftloc + "\\" + shortname + "_" + str(i) + extension)
# else if the original file didn't satisfy the if, the save it.
else:
mxd.saveACopy(draftloc + "\\" + result_name)
