Converted .py file to .exe and .exe file wont open properly

So I recently managed to convert a .py file into .exe but the problem is that the .exe file wont open properly. Basically what happens is the command prompt opens for a second and then shows some code for 1 milisecond and closes. I did manage to get a screenshot of what the command prompt says.This keeps happening when I try to open it but not with just that file, but every .py file I convert into .exe
I made a simple code to check if it was only like that for my previous code but its for every code that I make. I also used PyInstaller to convert the .py file into a .exe
import customtkinter as tk
import sys
import os
root = tk.CTk()
root.state('zoomed')
root.wm_title("Test File")
frame = tk.CTkFrame(master=root, height=300, width=600)
frame.pack_propagate(0)
frame.pack(pady=200)`
lbl = tk.CTkLabel(master=frame, text="I like chicken nuggets.", font=("Bahnschrift", 30))
lbl.pack(pady=120)
root.mainloop()
If something is unclear about my explanation, please ask. Im on Windows 11 and I use VS Code.
I asked for help on Discord but no luck. Im hoping somebody could help me here. I want my .exe file to open up like a charm and do its job.

I suggest using auto-py-to-exe since it's easier to use. To install type this:
pip install auto-py-to-exe
To run type this:
auto-py-to-exe
Then you'll see something like this:
Add the path to your script and you can change any setting you want
Then you'll need to add the path to your custontkinter package
Go to Additional Files -> Add Folder -> locate your python folder -> Lib -> site-packages -> customtkinter and add it to your exe
Scroll down and you'll see this button. Press it and your exe should work

Python: no module named 'bottle-websocket' when running an executable made with PyInstaller, including Eel module

I was playing around with the eel module for Python - gives an opportunity to run HTML + CSS/JS with the python functionality.
Made a simple program, tried to make an executable out of it via PyInstaller.
No errors whatsoever, but when running this executable it crashes on the first line - import eel, telling - there is no module called 'bottle-websocket'.
I checked pip: eel, bottle-websocket are installed. Can't figure out what's the problem. Attachments:
main.py:
import eel
from os import path
eel.init(path.dirname(__file__) + "/web")
eel.start('main.html', block=False)
while True:
eel.sleep(10)
Error:
Picture with the error while I try to start the exe
EDIT:
PyInstaller Log

I was also having this same issue, but I finally fixed it, it was actually very very easy, first of all make sure you are using auto-py-to-exe to package your app.
After inserting necessary details (script file,, extra files etc), you would see an advanced options tab probably below, click on it to expand it, look for the hidden imports label and insert "bottle-websocket" in the input field representing the hidden imports, that's basically all you need to do
I HOPE THIS HELPS

Took me the whole day figuring out the solution, but finally, here it is:
Copy the plugin.py, server.py files from C:\Users\YOUR_USERNAME\AppData\Local\Programs\Python\Python36-32\lib\site-packages\bottle_websocket to C:\Users*YOUR_USERNAME*\AppData\Local\Programs\Python\Python36-32\Lib
Make sure you have this line as follows in your *.spec file generated by PyInstaller (FOR PYTHON 3.6 32bit):
datas=[('C:\Users\YOUR_USERNAME\AppData\Local\Programs\Python\Python36-32\lib\site-packages\eel\eel.js', 'eel'), ('PATH_TO_YOUR_WEB_FOLDER', 'YOUR_WEB_FOLDER_NAME')]
3)Run this command in cmd: python C:\Users\YOUR_USERNAME\AppData\Local\Programs\Python\Python36-32\lib\site-packages\eel\main.py HERE_SHOULD_BE_THE_PATH_TO_YOUR_WEB_FOLDER
this command will get the 'bottle-websocket' work and will make sure that it complies with the web folder and files.

Hidden .db files using Python and SQLite3

I am using sqlite3 and python for a new website I am creating. The problem is, the "files_storage.db" file I am trying to create will not appear in any Windows 10 Folder Window, PyCharm's Directory View, nor will it appear via the command line interface.
The catch to this is, if I execute my python script multiple times, I get an error that states the database file already exists... So this file is somewhere, I guess it is a game of cat and mouse to find it.
I have ran into this problem before, but I have ALWAYS been able to find the file via the command line. Usually, I wouldn't both yall with such a question but, this is really irking me and I am going to run into serious issues when it comes time to put this baby on a server. :(
thanks in advance, and here's some screenshots I suppose.

You are using a relative file path.
Relative paths are converted to absolute ones by something like os.path.join(os.getcwd(), <relative path>). So they depend on the current working directory of the process.
Try to open it with an absolute path (starting with drive letter) to avoid any ambiguities.

If you use just a filename without a path, the file will be saved in whatever the current working directory of the Python interpreter is.
To see where the current working directory is, add the following code to the beginning of your program:
import os
print(os.getcwd())
You should then see the working directory in the output.
There is a setting for the current working directory in your IDE somewhere. See e.g. the answers to this question.

You can also do something like:
import os
path = os.path.expanduser("~") + '/Documents'
print(path)
This will allow you to access the directories for the current user. For me, this prints:
'/Users/thomasweeks/Documents'

Python Tkinter - .py file doesn't work when double clicked

I am running Windows 7 and have Python 3.3 64 bit installed. I seem to have a problem importing the tkinter module, I can import it fine through the python IDLE and it will work, but when I save the .py file and double click it, a cmd window will open and say:
Traceback (most recent call last):
File "C:Users\username\Desktop\g.py", line 3, in <module>
from tkinter import *
ImportError: No module named tkinter
I have tried the following:
I have tried import tkinter, from tkinter import *, and import tkinter as tk and they don't seem to work when the .py file is opened directly (double clicked).
I also double checked the path variable and it was set correctly.
I uninstalled python and reinstalled it.
I checked to see if tkinter is in the folder C:\Python33\Lib\, and it is.
I do have a mainloop() in my program.
In my program, tkinter is all lowercase.
I tried a lot of solutions online from other posts, and they didn't work for me.
The top of my code is:
import sys
from tkinter import *
I don't know what I am missing, any suggestions?

I'm going to make this an answer then for anybody in the future.
The problem is that Windows is currently set to run all .py files with a different executable (probably a Python 2.x one) To fix the problem, follow these steps:
Right-click a .py file.
In the menu that pops up, go to Open with.
In the submenu that pops up, click on Choose default program...
A window will then appear. In this window, click on the Browse... button.
Then, go find the Python execuatble. It should be at C:\Python33\python3.3.exe. (There might be multiple pythonX.exe files. If one doesn't work, try another.)
Once you select it, click Open.
If done correctly, this procedure will manually reset the default executable for .py files to be the Python 3.x one. Meaning, your script should run fine now.

This is actually a simple solution.
You have:
from tkinter import *
You need:
from Tkinter import *
Capitalization is very specific!!!

Default working directory for Python IDLE?

Is there a configuration file where I can set its default working directory? It currently defaults to my home directory, but I want to set it to another directory when it starts. I know I can do "import os" followed by "os.chdir("")" but that's kind of troublesome. It'd be great if there is a conf file that I can edit and change that setting, but I am unable to find it.
In particular, I've looked into my OS (Ubuntu)'s desktop entry '/usr/share/applications/idle-python3.2.desktop', which doesn't contain a conf file, but points to '/usr/lib/python3.2/idlelib/PyShell.py', which points to config-*.def conf files under the same folder, with 'config-main.def' being the most likely candidate. However I am unable to find where the default path is specified or how it can be changed.
It seems that the path is hard-coded in PyShell.py, though I could be wrong with my limited knowledge on Python. I will keep looking, but would appreciate it if somebody knows the answer on top of his or her head. Thanks in advance.

I actually just discovered the easiest answer, if you use the shortcut link labeled "IDLE (Python GUI)". This is in Windows Vista, so I don't know if it'll work in other OS's.
1) Right-click "Properties".
2) Select "Shortcut" tab.
3) In "Start In", write file path (e.g. "C:\Users...").
This is also my answer here: Default save path for Python IDLE? Let me know if this works!

I've found a solution after looking into PyShell.py:
Create a python file under a preferred directory, in my case '~/.idlerc/init.py', and copy/paste the following lines:
import os
os.chdir('<your preferred directory>')
Pass "-r '~/.idlerc/init.py' " argument to the IDLE startup command, like the following (your exec location and name may vary depending on OS, etc):
/usr/bin/idle-python3.2 -n -r ~/.idlerc/init.py

Just use a shell script such as:
#!/bin/bash
cd /Users/pu/Projects/L-Python
/usr/bin/idle
and run that instead of stock idle. The example is on OS X, adapt to your system.

I'm new to python and learning from 'Dive into Python' by mark Pilgrim (can be found online free)
the answer is in chapter 2.4 - hope he doesn't mind me pasting it here as its also plugging his book and is in the GPL
Before you go any further, I want to briefly mention the library
search path. Python looks in several places when you try to import a
module. Specifically, it looks in all the directories defined in
sys.path. This is just a list, and you can easily view it or modify it
with standard list methods. (You'll learn more about lists later in
this chapter.)
Example 2.4. Import Search Path
import sys
sys.path
sys.path.append('/my/new/path')
It's a good book I am a programmer - usually I find learning from books sends me quickly to sleep - not the case here ....

All I had to do here (Linux Mint 18.2 Xfce) ...
Just add path in line "working directory" = "Arbeitsverzeichnis"

It can change depending on where you installed Python. Open up IDLE, import os, then call os.getcwd() and that should tell you exactly where your IDLE is working on.

One default path is specified in idlelib.IOBinding.IOBinding.dirname or idlelib.IOBinding.IOBinding.filename
Ubuntu
So my idle-python3.desktop
file in /usr/share/applications looks like this:
[Desktop Entry]
Name=IDLE (using Python-3)
Comment=Integrated Development Environment for Python (using Python-3)
Exec=python3 -c "import idlelib.IOBinding, os; idlelib.IOBinding.IOBinding.dirname='/DEFAULT/DIRECTORY';import idlelib.idle"
Icon=/usr/share/pixmaps/python3.xpm
Terminal=false
Type=Application
Categories=Application;Development;
StartupNotify=true
To use it you need to set /DEFAULT/DIRECTORY to your desired directory, copy it with root rights into /usr/share/applications. You can also use it for Python 2 but then you need to replace the 3s with 2s.
ConfigFiles
There are also extensions that can be loaded. These must be modules and you specify them by module name. The config files for IDLE are located in HOME/.idlerc and parsed with a configparser. I did not get further with this.

Here's a way to reset IDLE's default working directory for MacOS if you launch Idle as an application by double-clicking it. You need a different solution if you launch Idle from a command line in Terminal. This solution is a permanent fix. You don't have to rechange the directory everytime you launch IDLE. I wish it were easier.
The idea is to edit a resource file inside of the IDLE package in Applications.
Start by finding the the file. In Finder, go to IDLE in Applications (in the Python folder) as if you wanted to open it. Right click and select "show package contents". Open Contents, then open Resources. In Resources, you'll see a file called idlemain.py. This file executes when you launch idle and sets, among other things, the working directory. We're going to edit that.
But before you can edit it, you need to give yourself permission to write to it. To do that, right click on the idlemain.py and select get info. Scroll to the bottom of the getinfo window and you'll see the Sharing & Permissions section. On the bottom right there's a lock icom. Click the lock and follow the prompts to unlock it. Once it's unlocked, look to the left for the + (under the list of users with permissions). Click it. That will bring up a window with a list of users you can add. Select yourself (probably the name of your computer or your user account) and click Select. You'll see yourself added to the list of names with permissions. Click where is says "Read only" next to your name and change it to "Read & Write". Be careful not to change anything else. When you're done, click the lock again to lock the changes.
Now go back to idlemain.py and open it with any text editor (you could use Idle, TextEdit, or anything. Right under the import statement at the top is the code to change the default working directory. Read the comment if you like, then replace the single line of code under the comment with
os.chdir('path of your desired working directory')
Mine looks like this:
os.chdir('/Users/MyName/Documents/Python')
Save your changes (which should work because you gave yourself permission). Next time you start Idle, you should be in your desired working directory. You can check with the following commands:
import os
os.getcwd()

This ought to be the number one answer. I have been playing around this for an hour or more and nothing worked. Paul explains this perfectly. It's just like the PATH statement in Windows. I successfully imported a module by appending my personal "PythonModules" path/dir on my Mac (starting at "/users/etc") using a simple
import xxxx command in Idle.
