How To Install Py2exe In Ubuntu
IntroductionThis tutorial will get you up and running with a local Python 3 programming environment in Ubuntu 16.04.Python is a versatile programming language that can be used for many different programming projects. First published in 1991 with a name inspired by the British comedy group Monty Python, the development team wanted to make Python a language that was fun to use. Easy to set up, and written in a relatively straightforward style with immediate feedback on errors, Python is a great choice for beginners and experienced developers alike. Python 3 is the most current version of the language and is considered to be the future of Python.This tutorial will guide you through installing Python 3 on your local Linux machine and setting up a programming environment via the command line. This tutorial will explicitly cover the installation procedures for Ubuntu 16.04, but the general principles apply to any other distribution of Debian Linux. PrerequisitesYou will need a computer with Ubuntu 16.04 installed, as well as have administrative access to that machine and an internet connection.
Step 1 — Setting Up Python 3We’ll be completing our installation and setup on the command line, which is a non-graphical way to interact with your computer. That is, instead of clicking on buttons, you’ll be typing in text and receiving feedback from your computer through text as well. The command line, also known as a shell, can help you modify and automate many of the tasks you do on a computer every day, and is an essential tool for software developers. There are many terminal commands to learn that can enable you to do more powerful things. The article “” can get you better oriented with the terminal.On Ubuntu 16.04, you can find the Terminal application by clicking on the Ubuntu icon in the upper-left hand corner of your screen and typing “terminal” into the search bar. Click on the Terminal application icon to open it.
Alternatively, you can hit the CTRL, ALT, and T keys on your keyboard at the same time to open the Terminal application automatically.Ubuntu 16.04 ships with both Python 3 and Python 2 pre-installed. To make sure that our versions are up-to-date, let’s update and upgrade the system with apt-get:. sudo apt-get update. sudo apt-get -y upgradeThe -y flag will confirm that we are agreeing for all items to be installed, but depending on your version of Linux, you may need to confirm additional prompts as your system updates and upgrades.Once the process is complete, we can check the version of Python 3 that is installed in the system by typing:.
python3 -VYou will receive output in the terminal window that will let you know the version number. The version number may vary, but it will look similar to this. OutputPython 3.5.2To manage software packages for Python, let’s install pip:.
sudo apt-get install -y python3-pipA tool for use with Python, pip installs and manages programming packages we may want to use in our development projects. You can install Python packages by typing:. pip3 install packagenameHere, packagename can refer to any Python package or library, such as Django for web development or NumPy for scientific computing. So if you would like to install NumPy, you can do so with the command pip3 install numpy.There are a few more packages and development tools to install to ensure that we have a robust set-up for our programming environment:. sudo apt-get install build-essential libssl-dev libffi-dev python-devOnce Python is set up, and pip and other tools are installed, we can set up a virtual environment for our development projects. Step 2 — Setting Up a Virtual EnvironmentVirtual environments enable you to have an isolated space on your computer for Python projects, ensuring that each of your projects can have its own set of dependencies that won’t disrupt any of your other projects.Setting up a programming environment provides us with greater control over our Python projects and over how different versions of packages are handled.
This is especially important when working with third-party packages.You can set up as many Python programming environments as you want. Each environment is basically a directory or folder in your computer that has a few scripts in it to make it act as an environment.We need to first install the venv module, part of the standard Python 3 library, so that we can create virtual environments. Let’s install venv by typing:. sudo apt-get install -y python3-venvWith this installed, we are ready to create environments.
Let’s choose which directory we would like to put our Python programming environments in, or we can create a new directory with mkdir, as in:. mkdir environments. cd environmentsOnce you are in the directory where you would like the environments to live, you can create an environment by running the following command:. python3 -m venv myenvEssentially, this sets up a new directory that contains a few items which we can view with the ls command:. ls myenv. Outputbin include lib lib64 pyvenv.cfg shareTogether, these files work to make sure that your projects are isolated from the broader context of your local machine, so that system files and project files don’t mix. This is good practice for version control and to ensure that each of your projects has access to the particular packages that it needs.

Python Wheels, a built-package format for Python that can speed up your software production by reducing the number of times you need to compile, will be in the Ubuntu 16.04 share directory.To use this environment, you need to activate it, which you can do by typing the following command that calls the activate script:. source myenv/bin/activateYour prompt will now be prefixed with the name of your environment, in this case it is called myenv. Your prefix may look somewhat different, but the name of your environment in parentheses should be the first thing you see on your line:.This prefix lets us know that the environment myenv is currently active, meaning that when we create programs here they will use only this particular environment’s settings and packages.Note: Within the virtual environment, you can use the command python instead of python3, and pip instead of pip3 if you would prefer.
If you use Python 3 on your machine outside of an environment, you will need to use the python3 and pip3 commands exclusively.After following these steps, your virtual environment is ready to use. Step 3 — Creating a Simple ProgramNow that we have our virtual environment set up, let’s create a simple “Hello, World!” program. This will make sure that our environment is working and gives us the opportunity to become more familiar with Python if we aren’t already.To do this, we’ll open up a command-line text editor such as nano and create a new file:. nano hello.pyOnce the text file opens up in the terminal window we’ll type out our program: print('Hello, World!' )Exit nano by typing the control and x keys, and when prompted to save the file press y.Once you exit out of nano and return to your shell, let’s run the program:.
python hello.pyThe hello.py program that you just created should cause your terminal to produce the following output. OutputHello, World!To leave the environment, simply type the command deactivate and you will return to your original directory. At this point you have a Python 3 programming environment set up on your local Ubuntu machine and can begin a coding project!To set up Python 3 on another computer, follow the for,. You can also read about, which is especially useful when working on development teams.With your local machine ready for software development, you can continue to learn more about coding in Python by following “” and “”.
Py2exe Example
Since py2exe is missing from pypi it is not installed from the pip command in Python 2.7. It by default redirected to version which is meant for python 3.3.Before installing make sure VC is installed. One can download from.After installing the VC for windows put the path on the environment of the system.The Path for the VC for Python isC:Usersxxxxxxxxx.xxxxxxxAppDataLocalProgramsCommonMicrosoftVisual C for Python9.0VCbinAfter everything is set type the command from the command terminalpip install Tags.
