I'm getting a "FileNotFoundError" even though I'm making a file

Question

I'm trying to make a directory with a file in it

# lines 1-5
import logging, os

unix_doc_loc = '~\\byeStore'
win32_doc_loc = 'C:\\byeStore'

[...]
# line 108
class Store():
[...]
# lines 132-148
    def CacheCatalogue():
        import sys, os, time, platform, json
        byelogs.debug('sys, os and time were imported')
        # catalogue = Store.GetCatalogue() # commented out as this isn't functional yet
        catalogue = '{"lastUpdated": 1}'
        catalogue = json.loads(catalogue)
        byelogs.info('Catalogue recieved.')
        byelogs.debug(catalogue)
        if sys.platform == 'win32':
            byelogs.info('Detected Windows ({}). Using "C:\\byeStore\\"...'.format(sys.platform)) # line 142 - the troublesome line
            catcache = open('C:\\byeStore\\catalogue-cache.json', 'wt')
            byelogs.debug('Opened catcache')
        if catalogue['lastUpdated'] >= catcache['lastUpdated']:
            byelogs.info('Catalouge in cache is old. Updating...')
            catcache.write(catalogue)
            byelogs.info('Updated.')

Here's my terminal output

Z:\ByeStore\ByeStoreLibs>featuretest.py
Traceback (most recent call last):
  File "Z:\ByeStore\ByeStoreLibs\featuretest.py", line 5, in <module>
    byestore.Store.CacheCatalogue()
  File "Z:\ByeStore\ByeStoreLibs\src\byestore\__init__.py", line 142, in CacheCatalogue
    catcache = open('C:\\byeStore\\catalogue-cache.json', 'wt')
FileNotFoundError: [Errno 2] No such file or directory: 'C:\\byeStore\\catalogue-cache.json'

Z:\ByeStore\ByeStoreLibs>

I remember that the 'wt' part in open(file, 'wt') makes files. I even tried using "x", but that just didn't work, either. I just can't make the files for some reason.

My files are on GitHub, if you want the full source.

The `'w'` mode creates *files*, but not *directories*... Are you sure the full path up-to the file actually exists? — Tomerikoo, Jun 20 '21 at 19:16
Again, `mkdir` only creates the directory, i.e. the *last part* of the path. You need `mkdirs` to make sure it creates the *whole* path — Tomerikoo, Jun 20 '21 at 19:18

from pathlib import Path

d = "C:\\byeStore\\"
Path(d).mkdir(parents=True, exist_ok=True)
open(d + "catalogue-cache.json", 'w+')

Couple things here:

Create the directory first.
'w' is used for creating the file if it does not exist, not 't'.

`t` marks it as text, just for making sure that's clear to the interpreter, even though it's not necessary I use it just in case. – ByeMC Jun 20 '21 at 19:22
Would you mind elaborating on what the params parents=True and exist_ok=True mean? – Muhd Mairaj Jun 20 '21 at 20:37
parents=True creates the parent directories, exist_ok=True means it doesn't error if it already exists – Işık Kaplan Jun 20 '21 at 21:05
