Is there a way to run Python code without downloading Python? [duplicate] - python

How can I convert a .py to .exe for Python?
(8 answers)
Closed 1 year ago.
My internship has asked me to make my code executable for people who do not have Python downloaded. I can run parts of it on online Python compilers, but it uses different libraries that are not supported on those compilers. My program opens a .csv file specified by the user and filters it and writes the new data to a new .csv file. To implement the code online, I think I would need to learn JavaScript? Is there any other alternative? I appreciate any guidance provided!

You can create a standalone executable that includes your python script + all necessary files to run it. The users then just run ".exe" file without need to download and setup python environment. A great library to do it is cx-freeze

There is many online python runner. Example https://www.programiz.com/python-programming/online-compiler/

Python Compilation as executable stand alone application? [duplicate]

This question already has answers here:
Create a directly-executable cross-platform GUI app using Python
(13 answers)
Closed 8 years ago.
I wrote a small program in Python. Actually it's not even a program really :p.
It's just this:
print(1+1)
When I saved it, it saved it as py1.py (a python file). And apparently, Python files can be executed, and it executed fine.
Is there anyway to be able to compile it into bytecode? Also is there a way to make it a stand alone application?
I could be getting terms wrong, I'm more of a Java person. I'm new to Python.
Thanks!
First of all, as #emh pointed out this is a duplicate of several other questions. One of them is stackoverflow.com/questions/2933/an-executable-python-app
There are several sets of scripts and modules that are available that allow you to convert a .py file into an standalone executable file. Some of the more popular ones are py2exe, py2app, Pyinstaller, and Cx_freeze. The one that is best for you depends you how you are using it. First, it depends on what operating you are using. py2exe is meant specifically for creating .exe files or windows executable files, py2app is the same as py2exe except it builds .app files for Mac OS, pyinstaller and cx_freeze can build an executable for multiple systems, including Windows, Mac OS, and Linux. Next, what you use depends on what version of Python you have. Cx_Freeze is the only one that I mentioned that supports python 3.X; the others only support Python 2.X. The advantage pyinstaller has, is it builds all the dependent files into one executable file that unpacks right before execution, whereas the others create a folder with lots dependent files along with the executable file. I use Cx_freeze, because of its python 3.x support and relatively easy building process.
As for converting it to bytecode, there are a couple python modules for this. One is py_compile. an example of this is:
import py_compile
py_compile.compile('filepathandname')
this will create a .pyc file, which python will put in a folder labeled __pycache__ in the same directory as the original file.
Hope this helped.

Hide/protect Python code [duplicate]

How do I protect Python code from being read by users?
(29 answers)
Closed 9 years ago.
I am writing code (Python and wxpython for GUI) which will run on Debian OS on Raspberry PI. I want to protect/hide the source code. Is there any way to do it? Probably py2exe, or converting it to a library or something else?
The compiled code (.pyc files) can be used if you wish for others to be able to execute but not to read or modify the source code (.py, .pyw).
Simply:
run your application
then copy all the relevant .pyc files into another folder and you should be able to
run it all from the new location
So long as all the appropriate modules are still able to be loaded, everything will work. This will require the version of python to be the same (can't run .pyc files from python 2.4 with python 2.7 and vice-versa)
The other thing to know is that strings will be preserved. You should open them up in a good text editor (I use vim) and inspect the content if you are worried about what others can see.
py2exe is of course another example, but you lose the ability to have cross-platform code at that point -- and if your application is for the Raspberry Pi -- that won't work.
Since you provided no other information about how you intend to run the code, it's not clear if the source will be a module or intended to be run directly. You should read this post to learn more.

how to tranfrom python3 program into exe file totally? [duplicate]

Python 3 project into exe?

Closed 9 years ago.
I have heard py2exe,but it doesn't support python3 now.So I found cxfreeze,but there is an problem that the extension lib are in a zip file,but one extension must use a txt file.The extension would figure out the txt file address,which in the zip file.Windows throw out an error of 'FileNotFoundError'.The problem nearly drive me mad.It can't open file that compressed in zip.I am begging for your help...
Reposting as an answer:
Programs that load data files may need to be modified a bit if they're looking for the data files adjacent to Python modules, because cx_Freeze puts the Python modules into a zip file. Depending on your use case, you could load the data from the zip file (using the zipfile module), or load it from a regular file alongside the exe. The cx_Freeze FAQ has an example of how to do the latter.
Another option, especially for small pieces of data, is to embed it in Python code so it's in a frozen module. Qt's resource system works like this.

How can I make an EXE file from a Python program?
I am looking for a method in which i can run python program without having packages installed in the system.
Is there any way by which we can directly run any python code as an *exe.
or Should I make a executable file which has all packages in it.
The main reason behind this is, able to run python program on system which is not having python/packages in it.
http://www.pyinstaller.org/ is another good option. Does a lot of the same things py2exe does and suffers from the same problems.
py2exe is what you want. This will build an executable from your source.
The downside is: it packs an interpreter with the exe, so the filesize might become bigger. And when you use external libraries, especially C-bindings, you'll have to make manual steps.

Distributing an executable zip file with __main__.py, how to access extra data? [duplicate]

python: can executable zip files include data files?
(4 answers)
Closed 7 years ago.
I'm doing a little program and I want to distribute it using this recipe:
single directory with __main__.py in it
zip this directory and adding a shebang on it #!/usr/bin/env python
making it executable
The problem is that in this package I have also extra files (I'm using pygtk toolkit and I need images and ui xml files). When I try to access these files I have the error that the resource is unavailable (the path that I'm trying to open is something like file.zip/gui/gui.ui ).
How can I handle this situation?
I figured out by myself, It's sufficient to use pkgutil.get_data to access the data inside a package.
