Python Create a nested directory inside a temporary Directory

python create directory
python mkdir
python unittest temporary directory
python create folder in current directory
python create temporary csv file
python tempfile cleanup
python 3.6 tempfile
tempfile mkdtemp delete

I'm working on a project using Python(3.7) in which I need to create a subdirectory inside a temporary directory, I have created my temporary directory as:

tempdir = tempfile.mkdtemp()
saved_unmask = os.umask(0o077)
temp_dir = os.path.join(tempdir)

Then I have tried to create a directory within this temp_dir as:

helm_chart = temp_dir + "/helmChart"['helm', 'create', helm_chart])

helm creates path/sub_path always create a directory inside path which is temp_dir in my case, the command above is creating a directory when I passed another directory path, but it's not creating a directory inside temp_dir.

Thanks in advance!

The following might work:

import os
os.makedirs(os.path.join(tempdir, 'helmChart'))

How can I safely create a nested directory?, First, the os module has to be loaded. os is a Python module which belongs to the import os # define the name of the directory to be created path = "/tmp/year" try: Keep in mind that the mkdir() method cannot create sub-directories on a  You can choose the location of this temporary directory by mentioning dir parameter. Following statement will create a temporary directory in C:\\python36 folder. >>> f = tempfile.TemporaryDirectory(dir = "C:/python36") <TemporaryDirectory 'C:/python36\\ tmp9wrjtxc_'>. The created directory appears in the dir1 folder.

You have saved_unmask = os.umask(0o077), is your script runs under your user? Possibly it doesn't have permission to write to the temporary directory

Creating and Deleting Directories with Python, directory unique to the test invocation, created in the base temporary directory. os CONTENT = "content" def test_create_file(tmp_path): d = tmp_path / "sub"  import os # define the name of the directory to be created path = "/tmp/year/month/week/day" try: os.makedirs(path) except OSError: print ("Creation of the directory %s failed" % path) else: print ("Successfully created the directory %s" % path) Listing 3. Creating a Temporary Directory

This can be solved by doing the following:

import os    
import tempdir

top_level = tempdir.TemporaryDirectory()
nested = tempdir.TemporaryDirectory(


This will output /tmp/{top_level_temp_dir}/{nested_temp_dir}

The key is the dir keyword argument. This tells the TemporaryDirectory to use the dir passed in as the base of the new TemporaryDirectory.

Temporary directories and files, While bugs in filesystems are not unknown, they are rare, far between, and usually a sub-sub-sub-directory supports the same semantics as the root directory. If we create the temporary directory using Python's built-in tempfile module,  Creates a temporary directory in the most secure manner possible. There are no race conditions in the directory’s creation. The directory is readable, writable, and searchable only by the creating user ID. The user of mkdtemp() is responsible for deleting the temporary directory and its contents when done with it.

DevOps in Python: Infrastructure as Python, Python's OS module provides a function to create a directory i.e. But neither temp or tempDir2 is present in current working directory. Hence it  This module generates temporary files and directories. It works on all supported platforms. In version 2.3 of Python, this module was overhauled for enhanced security. It now provides three new functions, NamedTemporaryFile (), mkstemp (), and mkdtemp (), which should eliminate all remaining need to use the insecure mktemp () function.

How to create a Directory in python ? –, Rather than having Python figure out what your current working directory is, you can just give os.listdir() a period in a string. For example, here's a listing of my '/​tmp/' directory (tmp is a directory that many What if we need to process files that are in a set of nested directories? It accepts a path and creates an object. I want to put output information of my program to a folder. if given folder does not exist, then the program should create a new folder with folder name as given in the program.
