I recently made a simple little game using python since I'm just learning programming and computer science. I was successful in making the game and converting it into an executable file using cx freeze. The problem now is that I can't run the application unless it is in the same folder with all the other components of the file (naturally). I was wondering how I would make a desktop application of my game without having to go into the folder in which the application was located in. Its really inconvenient to send entire folders to people so they can run my game.
Hope that makes sense,
Thanks
You can use another compiling module like pyinstaller as one example to include all required files and use the --onefile option to compile it into a single executable. In cx_freeze you can make installers by specify the bdist options. e.g. for windows python setup_file.py bdist_msi

I have created python desktop software. Now I want to market that as a product. But my problem is, anyone can decompile my exe file and they will get the actual code.
So is there any way to encrypt my code and convert it to exe before deployment. I have tried different ways.
But nothing is working. Is there any way to do that?.Thanks in advance
This link has most of the info you need.
But since links are discouraged here:
There is py2exe, which compiles your code into an .exe file, but afaik it's not difficult to reverse-engineer the code from the exe file.
You can of course make your code more difficult to understand. Rename your classes, functions to be non-sensical (e.g. rename print(s) to delete(s) or to a()) people will have a difficult time then.
You can also avoid all of that by using SaaS (Software as a Service), where you can host your code online on a server and get paid by people using it.
Or consider open-sourcing it :)
You can install pyinstaller per pip install pyinstaller (make sure to also add it to your environment variables) and then open shell in the folder where your file is (shift+right-click somewhere where no file is and "open PowerShell here") and the do "pyinstaller --onefile YOUR_FILE".
If there will be created a dist folder, take out the exe file and delete the build folder and the .spec I think it is.
And there you go with your standalone exe File.
I am coding a PyQt5 based GUI application needs to be able to create and run arbitrary Python scripts at runtime. If I convert this application to a .exe, the main GUI Window will run properly. However, I do not know how I can run the short .py scripts that my application creates. Is it possible to runs these without a system wide Python installation?
I don't want ways to compile my python application to exe. This problem relates to generated .py scripts
No, to run a Python file you need an interpreter.
It is possible that your main application can contain a Python interpreter so that you don't need to depend on a system-wide Python installation.
No, it won't work. But you can make a small tool that will load the scripts and eval them within the context of packed executable. Look here for more details. One thing to be mindful of is that your eval executable should import all the dependencies needed by your generated .py files
I have many python modules for my project. And I need to put those all on the server so that they will automatically run every week.
so now I am thinking about how I can move all those modules to the server. Should I package it up or should I make them into the exe file to be installed?. I do not make the GUI so I think might exe is not a good choice. but I am open to all suggestion because now I do not know exactly what I should do.
I used Pyinstaller to create a standalone exe file for a PyQt project. I did not use the single file option because the exe that is created with the single file option takes too long to open. Therefore, Pyinstaller created a dist folder that contains a bunch of files including my program.exe file. I would now like to create a setup.exe file that will place the contents of my dist folder in the program directory and create a shortcut in the start menu and on the desktop. I want it to be super simple for the user. Maybe like the setup.exe files that you get when you download a program from CNET. I found Inno-setup, which looks promising. However, I do not know if there any special considerations because the program is a standalone program create from a python/PyQt program. Thanks! Anyone have experience with this task? Is there a program everyone is using for this task that I do not know about?
Inno-Setup or NSIS are probably the easiest to use. You just tell them what files to include and where to put them and then they will create a nice installer for you. I wrote a short tutorial on my experiences using InnoSetup that you might find helpful:
http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/
Note that this tutorial was based around a wxPython app I wrote, but the concepts are the same.
I've been searching through SO for a while now trying to come up with an answer to this but due to my inexperience with programming I don't understand much of the documentation, nor am I confident enough to experiment too much.
Would anyone be able to describe in slightly simpler terms how I would use programs like Py2exe, PyInstaller, cx_freeze etc.? I just want a way for others (mainly friends) to be able to run my (simple, text only) program without having to download python themselves. If there is an easier way to do this I'd appreciate knowing that too.

There are two distinct ways of freezing python scripts to create executables:
Packing the interpreter and *.pyc files into one exe file-container. Such an approach is used by tools like PyInstaller, Py2exe, cx_freeze.
Creating native code from Python source, usually using a middle step of converting Python-source to C or C++ code. This is done by such tools as Shed-skin and Nuitka. The problem of this aproach is that such tools do not always support all the functionality of Python (e.g. they can have some typing limitations and so on)
The point where you have to start is reading the documentation. Such tools are not just push-and-run style tools, they usually have some configuration that must be implemented (that's the problem of possibly all build systems, and as the project grows, the configuration and number of hooks also grows).
You can start with Py2exe tutorial and 'hello-world' to get acquainted with that how compilation is done. As far as I know it's a simplest way to get your goal.
And the last thing, you can't create cross-platform native executables as their file formats are strongly operating system and hardware dependent.
Download py2exe
Download this msvcp90.dll
Copy your FileCode.py AND msvcp90.dll to C:\Python27\
In C:\Python27\ create new text file, then enter this code inside it:
from distutils.core import setup
import py2exe
setup(console=['Avril.py'])
Replace Avril.py with YourFileName.py
Save the file as setup.txt
Open CMD and type this:
cd C:\Python27\
python setup.txt py2exe
Now go to C:\Python27\dist\ and there's your .exe program.

Python scripts can be made directly executable, like shell scripts, by putting the python environment path in the top of the script file.
#!/usr/bin/env python3.5
The Python installer automatically associates .py files with python.exe so that a double-click on a Python file will run it as a script. The extension can also be .pyw, in that case, the console window that normally appears is suppressed.
Detailed description also for linux is here.
Install pyinstaller, a program that converts .py to .exe for python 2.7 to where python is located:
cd C:\python27\scripts
pip install pyinstaller
then move whatever python file you want to compile to C:\python27\scripts, compile from there by using:
pyinstaller --onefile yourfile.py
the --onefile is optional but it packages the whole thing(in this example yourfile.py) into one .exe. Once everything is done there will be 2 new folders along with a .spec file. From C:\python27\scripts open the folder dist. Your .exe will be located there in one file which you can double tap to execute and distribute to anyone who doesn't have python. Hope it helps.
