Create new folder with pathlib and write files into it

stackoverflow.com › questions › 47518669 › create-new-folder-with-pathlib-and-write-files-into-it

You could try:

p = pathlib.Path("temp/")
p.mkdir(parents=True, exist_ok=True)
fn = "test.txt" # I don't know what is your fn
filepath = p / fn
with filepath.open("w", encoding ="utf-8") as f:
    f.write(result)

You shouldn't give a string as path. It is your object filepath which has the method open.

Make new directories with Python's `Path.mkdir()` method

Sometimes we first have to make that path, and then call the mkdir() method to create the directory. Python has several ways to make a path object. One option is to join path components with the overloaded / (division) operator.

Create file if it doesn't exist, as well as its folders?

Much more readable (imo), and works on any OS: from pathlib import Path output_file = Path("/some/path/file.txt") output_file.parent.mkdir(exist_ok=True, parents=True) output_file.write_text("some text") Would recommend using the following for writing to the file though (handles closing the file for you, stream handling etc.) with open(output_file, 'w') as file: file.write("some text") More on reddit.com

How to subclass pathlib.Path so that it has _flavour and works just like pathlib.Path

This post raises a lot of questions. Firstly, what are you doing in that super call with Path.resolve(path_segments, strict=False)? resolve is an instance methods, and doesn't take a path_segments argument. Did you perhaps mean Path(path_segments).resolve(strict=False)? But even then, why are you trying to pass the resolved path object instead of the original argument? But probably most importantly, why do you think you need to subclass in order to make this work? Much better would be to use composition: create Dir as a standalone class that calls Path internally.

OS mkdir not making the directory in try statement

Several issues: 1 - the condition if os.mkdir == False: checks if the function itself is false, not the result from previous calls, the function is never False... os.mkdir throws an exception when it fails, so trying to use if conditions to check if it worked will fail. You can use a different function to check if a directory exists, https://www.geeksforgeeks.org/python-os-path-exists-method/ 2 - the check for equality to false needs to be done with == , not is... change this if storage_obj.exists() is False or sync_obj.exists() is False: 3 - your condition will proceed even if one of the directories doesn't exist, then you will try to make both, and one of them will hit an exception. split it... if not storage_obj.exists(): os.mkdir(storage_path) if not sync_obj.exists(): os.mkdir(sync_path) Besides that, your statement isn't clear enough... It always prints false you have 2 print lines that could potentially print false... print("path exists?", storage_obj.exists()) print("Path exists?", sync_obj.exists()) Which one prints false?

You could try:

p = pathlib.Path("temp/")
p.mkdir(parents=True, exist_ok=True)
fn = "test.txt" # I don't know what is your fn
filepath = p / fn
with filepath.open("w", encoding ="utf-8") as f:
    f.write(result)

You can directly initialize filepath and create parent directories for parent attribute:

from pathlib import Path

filepath = Path("temp/test.txt")
filepath.parent.mkdir(parents=True, exist_ok=True)

with filepath.open("w", encoding ="utf-8") as f:
    f.write(result)

r/learnpython on Reddit: Create file if it doesn't exist, as well as its folders?

August 5, 2022 -

I have the following code:

file = open('folder/subfolder/file.txt', 'w')
file.write('hello world')
file.close()

I get an error, however: FileNotFoundError: [Errno 2] No such file or directory

So naturally, I googled how to write to a file, creating it if it doesn't exist. And all the solutions are the same: Do what I did, but it only works if there's no missing subfolders.

How would I create the folder and subfolder (if they don't exist), and then write the file?

I suppose I could split the string, loop through each folder, and test for their existence. But is there a cleaner way to do this? It seems odd python is smart enough to create the file, but not enough to create the directory it's in as well.
