Python is interpreted, so it won't run without python. However, that doesn't mean that python has to be installed, you can include a copy in your program directory or even bundle your program and the python runtime into a single file. Here is a bad example: codebadfiles = 'virus.exe', 'exploit.application', 'internetexplorer.exe' def shouldallowprogram(filename): if filename in badfiles. Most of you may be curious to know about how to make a Trojan or Virus on your own. Well, here is an answer to your curiosity. In this, post I’ll show you how to make a simple trojan on your own using the C programming language. This trojan when executed will eat up the hard disk space on the root drive (The drive on which the Windows is installed, usually C: Drive) of the computer on which.

• Process to convert simple Python script into Windows executable [duplicate] 8 answers

I am looking for a way to convert a Python Program to a .exe file WITHOUT using py2exe. py2exe says it requires Python 2.6, which is outdated. Is there a way this is possible so I can distribute my Python program without the end-user having to install Python?

Understand that every 'freezing' application for Python will not really secure your code in any way. Every packaging system for a stand-alone executable Python 'program' will include a lot of the Python libraries and interpreter, which will make your program pretty large.

That said, PyInstaller has done a nearly flawless job with everything I've thrown at it. Currently it only supports up to Python 2.7 but Pyinstaller's support for a varied set of libraries large and small is unmatched in other 'freeze' type programs for Python.

some people talk very well about PyInstaller

I use cx_Freeze. Works with Python 2 and 3, and I have tested it to work on Windows, Mac, and Linux.

cx_Freeze: http://cx-freeze.sourceforge.net/

If it is a simple py scriptrefer here

Else for GUI :

$ pip3 install cx_Freeze

1) Create a setup.py file and put in the same directory as of the .py file you want to convert.

2)Copy paste the following lines in the setup.py and do change the 'filename.py' into the filename you specified.

3) Run the setup.py '$python setup.py build'

4)A new directory will be there there called 'build'. Inside it you will get your .exe file to be ready to launced directly.(Make sure you copy paste the images files and other external files into the build directory)

I've used cx-freeze with good results in Python 3.2

py2exe works with Python 2.7 (as well as other versions). You just need the MSVCR90.dll

Andy♦Andy

I've used py2exe in the past and have been very happy with it. I didn't particularly enjoy using cx-freeze as much, though

For this you have two choices:

• A downgrade to python 2.6. This is generally undesirable because it is backtracking and may nullify a small portion of your scripts
• Your second option is to use some form of exe converter. I recommend pyinstaller as it seems to have the best results.

There is another way to convert Python scripts to .exe files. You can compile Python programs into C++ programs, which can be natively compiled just like any other C++ program.

Can I create a Python program, send it to a remote computer, and run it there without that computer having Python installed? I've heard that you cannot, as Python needs to be interpreted. If this is true, then it seems very odd as it would be hard to distribute your program unless everyone decides to install Python.

Also, what about C and C++? Can they be run on a remote computer without having the language installed? (I think you can, as it is a compiled language).

How To Write A Virus

I'm not exactly sure and would like clarification.

EDIT:

Do I Have A Virus Program

I'm getting some mixed answers on this and am not sure where to go. I see that I can include the Python library in the program and I can use py2exe.

However, I'm confused on C and C++. Do I have to include their libraries in the program? Can they only be run on certain machines? Does the compiler allow it to run on all machines?

Look at py2exe and py2app for Windows and Mac. Macs running OSX and most modern Linuces have Python installed, however.

C/C++ apps are normally compiled to executables which work on one machine/OS architecture (e.g. 32-bit Windows, or 64-bit OSX); such an executable can run on some but not all machines. For example, 64-bit Windows or OSX can run programs built either for the 32-bit or 64-bit flavor of their respective OSes.

python is interpreted, so it won't run without python. However, that doesn't mean that python has to be installed, you can include a copy in your program directory or even bundle your program and the python runtime into a single file.

C and C++ compilers toolchains generate machine code (in most cases, C interpreters do exist, as do C and C++ -> p-code and bytecode compilers). But most C and C++ programs use shared libraries, and will not run unless the shared library is present (again, doesn't have to be installed, can be placed in the program directory). There's also usually a build option (static linking) to include all necessary libraries in the main program file.

But the result is still limited to a particular combination of OS and CPU architecture. Getting a program to run on more than a single platform always requires platform-specific runtime support.

You can use py2exe for distributing Python programs to Windows.

If a you have written a program in any language, and that program is not compiled to machine code, something on the user's computer must convert it to machine code before it can be run.

In the case of JavaScript, that 'something' is often a web browser. In the case of Python, that is often a stand-alone interpreter, though it is possible to compile it:

However, to be clear: just because your program is not compiled to imachine code does not mean that it will be interpreted. Programs written in C# are usually compiled to MSIL, which is compiled to machine code the first time the program is run. Java programs are also compiled when they are first run.

I will give a practical application of sending code to a remote machine to run. This is typically done in the BOINC project, a community GRID computing initiative which has produced gems such as SETI@Home. The applications typically are compiled C++ versions with multi-platform binaries for x86-linux, AMD64-linux, win32, win64 and Mac OS Universal Binaries (with ppc,x86 and 64-bit). This is a lot of variety for distribution, but a modern make system can easily automate all that (e.g. CMake).

A lot of people prefer the WORA method (write once run anywhere) and stick with VM based language like Java or Python. In this case the boinc projects distribute a version of the VM as well as the code to run on it. Java VM's being encumbered with licensing issues, Python VM is much nicer. Boinc is attempting to embed the Python VM in various BOINC clients to make the distribution of Python based GRID applications easier.

I hope this gives you an idea about application distribution and helps you make an informed decision.

There is a py2exe that can produce an executable that will run on another computer without that user installing the normal Python package.

Yes, C and C++ are (at least normally) implemented as compilers that can produce standalone executables.

Edit: In a typical case, a C or C++ implementation will link the functions from the standard library that are used in the program into the executable. This can (and often does) include quite a bit that's not used directly, but still doesn't normally include (anywhere close to) the entire standard library.

In most cases you can also produce an executable that depends on an implementation of the standard library already being present on the target machine in the form of a shared library, DLL, etc. (different OSes use different names). This reduces the size of the executable, but increases the headaches involved in distribution; I use it for code I'm compiling on my own machine, but generally avoid it when/if I'm distributing an executable to anybody else. Given current hard drive prices, the savings in disk space is rarely worth the headache.

Look into Pyinstaller for standalone executables with no python integration needed. Well, apart from the crucial libraries so it can run!

It's recently updated, well maintained and even supports cython integration though that can get complex. You can compress the files to be smaller or if you have multiple executables, you can link them to one file to reduce size.

You can also of course create a single executable with python installed. Don't use anaconda though (use default python 3.6) to ensure your program is very small in size.

Hope this helps.
