Note for additional information - I went through the Python exception hierarchy but unfortunately, I don't see any exception for PathNotFound and SoftwareVersionNotFound scenarios related error. ... What code do you have right now? You'd use os.path.isdir(...) to figure out if ... exists and is a directory. ... As you can see here, you could use OSError that can handle also I/O failures such as “file not found”. You can also use another built-in exception like FileNotFoundError.

How to handle file not found error in Python | LabEx
The most common and recommended way to handle the FileNotFoundError in Python is by using a try-except block. This allows you to gracefully catch the exception and execute alternative code when the file is not found.

I divided by zero on purpose. However I made a string file that doesn't exist, and when I go to the except clause it is not catching, it keeps terminating the program instead of catching the exception. Why is that?
for i in listr:
if type(i) == str:
Path(i).read_text()
try:
i = i/0
except FileNotFoundError:
print('File not Found ')
except ZeroDivisionError:
print('Divided by zero')

I think this is mostly a case of properly indenting. Is this what you're trying to do? from pathlib import Path listr = ['i_exist.txt', 'i_do_not.txt'] for i in listr: if type(i) == str: try: print(Path(i).read_text()) except FileNotFoundError: print('File not Found')

try block should be around open. Not around prompt.
while True:
prompt = input("\n Hello to Sudoku valitator,"
"\n \n Please type in the path to your file and press 'Enter': ")
try:
sudoku = open(prompt, 'r').readlines()
except FileNotFoundError:
print("Wrong file or file path")
else:
break

You can try adding this code before open() function:
import os
pathname = __file__
os.chdir(os.path.dirname(pathname))

8. Errors and Exceptions — Python 3.14.4 documentation
If an exception occurs which does not match the exception named in the except clause, it is passed on to outer try statements; if no handler is found, it is an unhandled exception and execution stops with an error message.

so this happened to me on windows recently. I fix it by following the following steps using a PowerShell with admin privileges:
- delete
node_modulesfolder - running
npm install --global windows-build-toolswith administrative privilege. (in my case need restart - and restart without ask!!!) - reinstalling node modules or node-sass with
npm install

The error message means that it cannot locate your python executable or binary.
In many cases, it's installed at c:\python27.
if it's not installed yet, you can install it with npm install --global windows-build-tools, which will only work if it hasn't been installed yet.
Adding it to the environment variables does not always work. A better alternative, is to just set it in the npm config.
npm config set python "C:\Python27\python.exe"

FileNotFoundError | Python’s Built-in Exceptions – Real Python
FileNotFoundError is a built-in exception that occurs when an operation requires a file or directory that doesn’t exist in the specified location. It’s a subclass of OSError designed to signal that the file or directory you’re trying to access couldn’t be found. You can use this exception to handle cases where your code relies on external files or directories that might not be present.

Python Program for Handling FileNotFoundError
However, if a FileNotFoundError exception occurs because the file does not exist, the program jumps to the except block. In the except block, we handle the exception by printing an error message indicating that the file was not found.

Exception Handling — Programming in Python 7.0 documentation
In this case, it’s opening and processing a file. But if the file isn’t there, then a FileNotFoundError is “raised”. When an Exception is raised, no further code is run – so the process() function will not be called. Once an exception is raised, Python looks for an except line.
