I'm building a Python application and don't want to force my clients to install Python and modules.
So, is there a way to compile a Python script to be a standalone executable?

You can use PyInstaller to package Python programs as standalone executables. It works on Windows, Linux, and Mac.
PyInstaller Quickstart
Install PyInstaller from PyPI:
pip install pyinstaller
Go to your program’s directory and run:
pyinstaller yourprogram.py
This will generate the bundle in a subdirectory called dist.
pyinstaller -F yourprogram.py
Adding -F (or --onefile) parameter will pack everything into single "exe".
pyinstaller -F --paths=<your_path>\Lib\site-packages yourprogram.py
running into "ImportError" you might consider side-packages.
pip install pynput==1.6.8
still runing in Import-Erorr - try to downgrade pyinstaller - see Getting error when using pynput with pyinstaller
For a more detailed walkthrough, see the manual.

You can use py2exe as already answered and use Cython to convert your key .py files in .pyc, C compiled files, like .dll in Windows and .so on Linux.
It is much harder to revert than common .pyo and .pyc files (and also gain in performance!).

You might wish to investigate Nuitka. It takes Python source code and converts it in to C++ API calls. Then it compiles into an executable binary (ELF on Linux). It has been around for a few years now and supports a wide range of Python versions.
You will probably also get a performance improvement if you use it. It is recommended.

Yes, it is possible to compile Python scripts into standalone executables.
PyInstaller can be used to convert Python programs into stand-alone executables, under Windows, Linux, Mac OS X, FreeBSD, Solaris, and AIX. It is one of the recommended converters.
py2exe converts Python scripts into only executable on the Windows platform.
Cython is a static compiler for both the Python programming language and the extended Cython programming language.

I would like to compile some useful information about creating standalone files on Windows using Python 2.7.
I have used py2exe and it works, but I had some problems.
It has shown some problems for creating single files in Windows 64 bits: Using bundle_files = 1 with py2exe is not working;
It is necessary to create a setup.py file for it to work. http://www.py2exe.org/index.cgi/Tutorial#Step2;
I have had problems with dependencies that you have to solve by importing packages in the setup file;
I was not able to make it work together with PyQt.
This last reason made me try PyInstaller http://www.pyinstaller.org/.
In my opinion, it is much better because:
It is easier to use.
I suggest creating a .bat file with the following lines for example (pyinstaller.exe must be in in the Windows path):
pyinstaller.exe --onefile MyCode.py
You can create a single file, among other options (https://pyinstaller.readthedocs.io/en/stable/usage.html#options).
I had only one problem using PyInstaller and multiprocessing package that was solved by using this recipe: https://github.com/pyinstaller/pyinstaller/wiki/Recipe-Multiprocessing.
So, I think that, at least for python 2.7, a better and simpler option is PyInstaller.

And a third option is cx_Freeze, which is cross-platform.

pyinstaller yourfile.py -F --onefile
This creates a standalone EXE file on Windows.
Important note 1: The EXE file will be generated in a folder named 'dist'.
Important note 2: Do not forget --onefile flag
You can install PyInstaller using pip install PyInstaller
NOTE: In rare cases there are hidden dependencies...so if you run the EXE file and get missing library error (win32timezone in the example below) then use something like this:
pyinstaller --hiddenimport win32timezone -F "Backup Program.py"

I like PyInstaller - especially the "windowed" variant:
pyinstaller --onefile --windowed myscript.py
It will create one single *.exe file in a distination/folder.

You may like py2exe. You'll also find information in there for doing it on Linux.

Use py2exe.... use the below set up files:
from distutils.core import setup
import py2exe
from distutils.filelist import findall
import matplotlib
setup(
console = ['PlotMemInfo.py'],
options = {
'py2exe': {
'packages': ['matplotlib'],
'dll_excludes': ['libgdk-win32-2.0-0.dll',
'libgobject-2.0-0.dll',
'libgdk_pixbuf-2.0-0.dll']
}
},
data_files = matplotlib.get_py2exe_datafiles()
)

I also recommend PyInstaller for better backward compatibility such as Python 2.3 - 2.7.
For py2exe, you have to have Python 2.6.

For Python 3.2 scripts, the only choice is cx_Freeze. Build it from sources; otherwise it won't work.
For Python 2.x I suggest PyInstaller as it can package a Python program in a single executable, unlike cx_Freeze which outputs also libraries.

Since it seems to be missing from the current list of answers, I think it is worth mentioning that the standard library includes a zipapp module that can be used for this purpose. Its basic usage is just compressing a bunch of Python files into a zip file with extension .pyz than can be directly executed as python myapp.pyz, but you can also make a self-contained package from a requirements.txt file:
$ python -m pip install -r requirements.txt --target myapp
$ python -m zipapp -p "interpreter" myapp
Where interpreter can be something like /usr/bin/env python (see Specifying the Interpreter).
Usually, the generated .pyz / .pyzw file should be executable, in Unix because it gets marked as such and in Windows because Python installation usually registers those extensions. However, it is relatively easy to make a Windows executable that should work as long as the user has python3.dll in the path.
If you don't want to require the end user to install Python, you can distribute the application along with the embeddable Python package.

py2exe will make the EXE file you want, but you need to have the same version of MSVCR90.dll on the machine you're going to use your new EXE file.
See Tutorial for more information.

You can find the list of distribution utilities listed at Distribution Utilities.
I use bbfreeze and it has been working very well (yet to have Python 3 support though).

Not exactly a packaging of the Python code, but there is now also Grumpy from Google, which transpiles the code to Go.
It doesn't support the Python C API, so it may not work for all projects.

Using PyInstaller, I found a better method using shortcut to the .exe rather than making --onefile. Anyway, there are probably some data files around and if you're running a site-based app then your program depends on HTML, JavaScript, and CSS files too. There isn't any point in moving all these files somewhere... Instead what if we move the working path up?
Make a shortcut to the EXE file, move it at top and set the target and start-in paths as specified, to have relative paths going to dist\folder:
Target: %windir%\system32\cmd.exe /c start dist\web_wrapper\web_wrapper.exe
Start in: "%windir%\system32\cmd.exe /c start dist\web_wrapper\"
We can rename the shortcut to anything, so renaming to "GTFS-Manager".
Now when I double-click the shortcut, it's as if I python-ran the file! I found this approach better than the --onefile one as:
In onefile's case, there's a problem with a .dll missing for the Windows 7 OS which needs some prior installation, etc. Yawn. With the usual build with multiple files, no such issues.
All the files that my Python script uses (it's deploying a tornado web server and needs a whole freakin' website worth of files to be there!) don't need to be moved anywhere: I simply create the shortcut at top.
I can actually use this exact same folder on Ubuntu (run python3 myfile.py) and Windows (double-click the shortcut).
I don't need to bother with the overly complicated hacking of .spec file to include data files, etc.
Oh, remember to delete off the build folder after building. It will save on size.

Use Cython to convert to C, compile, and link with GCC.
Another could be, make the core functions in C (the ones you want to make hard to reverse), compile them and use Boost.Python to import the compiled code (plus you get a much faster code execution). Then use any tool mentioned to distribute.

I'm told that PyRun is also an option. It currently supports Linux, FreeBSD and Mac OS X.

Creating an exe file for windows using mac for my Kivy app

I've created a kivy app that works perfectly as I desire. It's got a few files in a particular folder that it uses. For the life of me, I don't understand how to create an exe on mac. I know I can use pyinstaller but how do I create an exe from mac.
Please help!

For pyinstaller, they have stated that packaging Windows binaries while running under OS X is NOT supported, and recommended to use Wine for this.
Can I package Windows binaries while running under Linux?
No, this is not supported. Please use Wine for this, PyInstaller runs
fine in Wine. You may also want to have a look at this thread in the
mailinglist. In version 1.4 we had build in some support for this, but
it showed to work only half. It would require some Windows system on
another partition and would only work for pure Python programs. As
soon as you want a decent GUI (gtk, qt, wx), you would need to install
Windows libraries anyhow. So it's much easier to just use Wine.
Can I package Windows binaries while running under OS X?
No, this is not supported. Please try Wine for this.
Can I package OS X binaries while running under Linux?
This is currently not possible at all. Sorry! If you want to help out,
you are very welcome.

This is easy with Pyinstaller. I've used it recently.
Install pyinstaller
pip install pyinstaller
Hit following command on terminal where file.py is path to your main file
pyinstaller -w -F file.py
Your exe will be created inside a folder dist
NOTE : verified on windowns, not on mac

How can I make portable python desktop application?

The requirement is to make an application portable, meaning no installer. I looked at py2exe and I am afraid I need to run install if I want to run it under Windows.
So my question is, can I make a portable python desktop application without any installation (all dependencies and libs are packaged), dragging from USB / CD will run it?
(This is critical because it's a headache for users to install C++ Run Time library...)
Thanks.

You can use this method with py2exe: http://www.py2exe.org/index.cgi/SingleFileExecutable
Basically, you use NSIS to package all of the required files and folders into a single executable. When you run it, the required files are expanded to a temporary directory, the executable is run, and when it exits, the temporary files are deleted automatically.
There is also an example that comes with py2exe which uses Inno Setup instead of NSIS to achieve the same result. It's installed to site-packages\py2exe\samples\extending.

You can also fork Portable Python and modify to include your application and libraries you need. It runs from any drive/network location without installation and you can pick do you want 2.x.x or 3.x.x based Python core
