Iam coding in vs code with python3.
in the tutorial says that you should write
f=open("filename.txt")
and then run it and if you want to read it
f=open("filename.txt","r")
and I write a txt in my computre and I'm sure its exicts in my loptop but every time I run the code it gives me :(FileNotFoundError: [Errno 2] No such file or directory)
what should I do?
You can try to change "filename.txt" for the absolute path of that file. That means you should go to your file and copy the exact complete path from the storage through all directories until reaching it:
f=open("filename.txt","r")
f=open(r"C:\\Users\\your_user\\Desktop\\filename.txt","r") #Example of an absolute path, in this case the file is in Desktop but you have to copy the exact path you have
If that doesn't work, the file might be corrupted or defective, so you would have to try other solutions.

My work needs me to collect some file names and their generating time.
I am using the fileName = tkinter.filedialog.askopenfilenames() to realize the function, that the program pops up a window to ask for selecting files, then I can get the files' pathes and then use fileGeneratedTime = datetime.datetime.fromtimestamp(os.path.getmtime(fileName)) to get the files' generating time.
But now here comes the problem. When I want to get the path of a .lnk file, however, it returns the path of the file which the .lnk file is pointing to. It is OK to run the program on the origin computer that has the .lnk files, but when I copy the .lnk files to other computers, the program says FileNotFoundError.
So, is there any parameters that can make the fileName = tkinter.filedialog.askopenfilenames() returns the .lnk file itself's path (not the path of the file which the .lnk file points to)? Or is there any other ways to realize the same function?
Thanks for your answering!
I am working on the listener portion of a backdoor program (for an ETHICAL hacking course) and I would like to be able to read files from any part of my linux system and not just from within the directory where my listener python script is located - however, this has not proven to be as simple as specifying a typical absolute path such as "~/Desktop/test.txt"
So far my code is able to read files and upload them to the virtual machine where my reverse backdoor script is actively running. But this is only when I read and upload files that are in the same directory as my listener script (aptly named listener.py). Code shown below.
def read_file(self, path):
with open(path, "rb") as file:
return base64.b64encode(file.read())
As I've mentioned previously, the above function only works if I try to open and read a file that is in the same directory as the script that the above code belongs to, meaning that path in the above content is a simple file name such as "picture.jpg"
I would like to be able to read a file from any part of my filesystem while maintaining the same functionality.
For example, I would love to be able to specify "~/Desktop/another_picture.jpg" as the path so that the contents of "another_picture.jpg" from my "~/Desktop" directory are base64 encoded for further processing and eventual upload.
Any and all help is much appreciated.
Edit 1:
My script where all the code is contained, "listener.py", is located in /root/PycharmProjects/virus_related/reverse_backdoor/. within this directory is a file that for simplicity's sake we can call "picture.jpg" The same file, "picture.jpg" is also located on my desktop, absolute path = "/root/Desktop/picture.jpg"
When I try read_file("picture.jpg"), there are no problems, the file is read.
When I try read_file("/root/Desktop/picture.jpg"), the file is not read and my terminal becomes stuck.
Edit 2:
I forgot to note that I am using the latest version of Kali Linux and Pycharm.
I have run "realpath picture.jpg" and it has yielded the path "/root/Desktop/picture.jpg"
Upon running read_file("/root/Desktop/picture.jpg"), I encounter the same problem where my terminal becomes stuck.
[FINAL EDIT aka Problem solved]:
Based on the answer suggesting trying to read a file like "../file", I realized that the code was fully functional because read_file("../file") worked without any flaws, indicating that my python script had no trouble locating the given path. Once the file was read, it was uploaded to the machine running my backdoor where, curiously, it uploaded the file to my target machine but in the parent directory of the script. It was then that I realized that problem lied in the handling of paths in the backdoor script rather than my listener.py
Credit is also due to the commentator who pointed out that "~" does not count as a valid path element. Once I reached the conclusion mentioned just above, I attempted read_file("~/Desktop/picture.jpg") which failed. But with a quick modification, read_file("/root/Desktop/picture.jpg") was successfully executed and the file was uploaded in the same directory as my backdoor script on my target machine once I implemented some quick-fix code.
My apologies for not being so specific; efforts to aid were certainly confounded by the unmentioned complexity of my situation and I would like to personally thank everyone who chipped in.
This was my first whole-hearted attempt to reach out to the stackoverflow community for help and I have not been disappointed. Cheers!
A solution I found is putting "../" before the filename if the path is right outside of the dictionary.
test.py (in some dictionary right inside dictionary "Desktop" (i.e. /Desktop/test):
with open("../test.txt", "r") as test:
print(test.readlines())
test.txt (in dictionary "/Desktop")
Hi!
Hello!
Result:
["Hi!", "Hello!"]
This is likely the simplest solution. I found this solution because I always use "cd ../" on the terminal.
This not only allows you to modify the current file, but all other files in the same directory as the one you are reading/writing to.
path = os.path.dirname(os.path.abspath(__file__))
dir_ = os.listdir(path)
for filename in dir_:
f = open(dir_ + '/' + filename)
content = f.read()
print filename, len(content)
try:
im = Image.open(filename)
im.show()
except IOError:
print('The following file is not an image type:', filename)
I have files .sh files and .json files in which there are file paths given to point to a specific directory, but I should keep on changing the file path, depending on where my python scipt is run.
eg:content of one of my .sh file is
"cd /home/aswany/BotStudioInstallation/databricks/platform/databricksastro"
and I should change the file path via python code where the following path
"/home/aswany/BotStudioInstallation/" keep on changing depending on where databicks is located,
I tried the following code:
replaceAll(str(self.currentdirectory)+
"/databricks/platform/devsettings.json",
"/home/holmes/BotStudioInstallation",self.currentdirectory)
and function replaceAll is:
def replaceAll(self,file,searchExp,replaceExp):
for line in fileinput.input(file, inplace=1):
if searchExp in line:
line = line.replace(searchExp,replaceExp)
sys.stdout.write(line)
but above code only replaces a line
"home/holmes/BotStudioInstallation" to the current directory I am logged in,bt it cannot be sure that "home/holmes/BotStudioInstallation" is the only possibility it keep on changing like "home/aswany/BotStudioInstallation","home/dev3/BotStudioInstallation" etc ,I thought of regular expression for this.
please help me
Not sure I 100% understood your issue, but maybe I can help nonetheless.
As pointed out by J.F. Sebastian, you can use relative paths and remove the base part of the path. Using ./databricks/platform/devsettings.json might be enough. This is by far the most elegant solution.
If for any reason it is not, you can keep the directory you need to access, then append it to the base directory whenever you need it. That should allow you to deal with changes in the base directory. Though in the case the files will be used by other applications than your own, that might not be an option.
dir = get_dir_from_json()
dir_with_base = self.currentdirectory + dir
Alternatively, not an elegant solution though, without using regex you can use a "pattern" to always replace.
{
"directory": "<<_replace_me_>>/databricks/platform"
}
Then you know you can always replace "<<_replace_me_>>" with the base directory.
I have simple code:
from xlrd import open_workbook
open_workbook('Book1.xls')
No matter how I save the file (xls or xlsx) or how I change the path to the file (C:\Users\... or C:\Users...) I keep getting:
IOError: [Errno 2] No such file or directory: '(insert whatever is in place of Book1.xls)'
I don't know what I could be doing wrong. I'm not trying anything specific yet I just want it to not throw up an error.
You are not including whole path of the file. The path will be looks like:
file="C:\\USER\\TEST\\FILENAME"
or
file=r":\USER\TEST\FILENAME"
If you are using single slash then you need to use 'r' or else it will throw error.
you are not doing workbook("Book1.xls")
you are passing it a path (with directories) ... one of the folders in the path doesnt exist
this is probably because you do something like
directory="C:\Users\Blah\..."
when you need to do
directory = r"C:\Users\Blah\..."
other wise the backslashes serve to escape the next character
Long time reader, first time poster. I am very new to python and I will try to ask my question properly.
I have posted a snippet of the .py code I am using below. I am attempting to get the latest modified file in the current directory to be listed and then pass it along later in the code.
This is the error I get in my log file when I attempt to run the file:
WindowsError: [Error 2] The system cannot find the file specified: '05-30-2012_1500.wav'
So it appears that it is in fact pulling a file from the directory, but that's about it. And actually, the file that it pulls up is not the most recently modified file in that directory.
latest_page = max(os.listdir("/"), key=os.path.getmtime)
cause = channel.FilePlayer.play(latest_page)
os.listdir returns the names of files, not full paths to those files. Generally, when you use os.listdir(SOME_DIR), you then need os.path.join(SOME_DIR, fname) to get a path you can use to work with the file.
This might work for you:
files = [os.path.join("/", fname) for fname in os.listdir("/")]
latest = max(files, key=os.path.getmtime)
cause = channel.FilePlayer.play(latest)
