Python open("file", "w+") not creating a nonexistent file

November 15, 2021

Similar questions exist on Stack Overflow. I have read such questions and they have not resolved my problem. The simple code below results in a File Not Found Error. I am running Python 3.9.1 on Mac OS X 11.4

Can anyone suggest next steps for troubleshooting the cause of this?

with open("/Users/root/test/test.txt", "w+") as f:
    f.write("test")

Traceback (most recent call last):
  File "/Users/root1/PycharmProjects/web_crawler/test.py", line 1, in <module>
    with open("/Users/root/test/test.txt", "w+") as f:
FileNotFoundError: [Errno 2] No such file or directory: '/Users/root/test/test.txt'

>Solution :

You comments on initial post clarify what you need to happen.
Below assumes that

The directory Users/root1/ exists
You are trying to create a new sub directory + file inside it

import os

# Wrap this in a loop if you need
new_dir = 'test' # The variable directory name
new_path = 'Users/root1/' + new_dir + "/"
os.makedirs(os.path.dirname(new_path), exist_ok=True) # Create new dir 'Users/root1/${new_dir}/

with open(new_path + "test.txt", "w+") as f:
    # Create new file in afore created directory
    f.write("test")

This creates a new directory based on a variable new_dir and creates the file test.txt in it.
