Python is available on a wide variety of platforms including Linux and Mac OS X. Let's understand how to set up our Python environment.
Local Environment Setup
Open a terminal window and type 'python' to find out if it is already installed and which version is installed.
- Unix (Solaris, Linux, FreeBSD, AIX, HP/UX, SunOS, IRIX, etc.)
- Win 9x/NT/2000
- Macintosh (Intel, PPC, 68K)
- OS/2
- DOS (multiple versions)
- PalmOS
- Nokia mobile phones
- Windows CE
- Acorn/RISC OS
- BeOS
- Amiga
- VMS/OpenVMS
- QNX
- VxWorks
- Psion
- Python has also been ported to the Java and .NET virtual machines
Getting Python
The most up-to-date and current source code, binaries, documentation, news, etc., is available on the official website of Python https://www.python.org/
You can download Python documentation from https://www.python.org/doc/. The documentation is available in HTML, PDF, and PostScript formats.
Installing Python
Python distribution is available for a wide variety of platforms. You need to download only the binary code applicable for your platform and install Python.
If the binary code for your platform is not available, you need a C compiler to compile the source code manually. Compiling the source code offers more flexibility in terms of choice of features that you require in your installation.
Here is a quick overview of installing Python on various platforms −
Unix and Linux Installation
Here are the simple steps to install Python on Unix/Linux machine.
Open a Web browser and go to https://www.python.org/downloads/.
Follow the link to download zipped source code available for Unix/Linux.
Download and extract files.
Editing the Modules/Setup file if you want to customize some options.
run ./configure script
make
make install
Xyz Mac Os Download
This installs Python at standard location /usr/local/bin and its libraries at /usr/local/lib/pythonXX where XX is the version of Python.
Windows Installation
Here are the steps to install Python on Windows machine.
Open a Web browser and go to https://www.python.org/downloads/.
Follow the link for the Windows installer python-XYZ.msi file where XYZ is the version you need to install.
To use this installer python-XYZ.msi, the Windows system must support Microsoft Installer 2.0. Save the installer file to your local machine and then run it to find out if your machine supports MSI.
Run the downloaded file. This brings up the Python install wizard, which is really easy to use. Just accept the default settings, wait until the install is finished, and you are done.
Macintosh Installation
Recent Macs come with Python installed, but it may be several years out of date. See http://www.python.org/download/mac/ for instructions on getting the current version along with extra tools to support development on the Mac. For older Mac OS's before Mac OS X 10.3 (released in 2003), MacPython is available.
Jack Jansen maintains it and you can have full access to the entire documentation at his website − http://www.cwi.nl/~jack/macpython.html. You can find complete installation details for Mac OS installation.
Setting up PATH
Programs and other executable files can be in many directories, so operating systems provide a search path that lists the directories that the OS searches for executables.
The path is stored in an environment variable, which is a named string maintained by the operating system. This variable contains information available to the command shell and other programs.
The path variable is named as PATH in Unix or Path in Windows (Unix is case sensitive; Windows is not).
In Mac OS, the installer handles the path details. To invoke the Python interpreter from any particular directory, you must add the Python directory to your path.
Setting path at Unix/Linux
To add the Python directory to the path for a particular session in Unix −
In the csh shell − type setenv PATH '$PATH:/usr/local/bin/python' and press Enter.
In the bash shell (Linux) − type export PATH='$PATH:/usr/local/bin/python' and press Enter.
In the sh or ksh shell − type PATH='$PATH:/usr/local/bin/python' and press Enter.
Note − /usr/local/bin/python is the path of the Python directory
Setting path at Windows
To add the Python directory to the path for a particular session in Windows −
At the command prompt − type path %path%;C:Python and press Enter.
Note − C:Python is the path of the Python directory
Python Environment Variables
Here are important environment variables, which can be recognized by Python −
Sr.No. | Variable & Description |
---|---|
1 | PYTHONPATH It has a role similar to PATH. This variable tells the Python interpreter where to locate the module files imported into a program. It should include the Python source library directory and the directories containing Python source code. PYTHONPATH is sometimes preset by the Python installer. |
2 | PYTHONSTARTUP It contains the path of an initialization file containing Python source code. It is executed every time you start the interpreter. It is named as .pythonrc.py in Unix and itcontains commands that load utilities or modify PYTHONPATH. |
3 | PYTHONCASEOK It is used in Windows to instruct Python to find the first case-insensitive match in an import statement. Set this variable to any value to activate it. |
4 | PYTHONHOME It is an alternative module search path. It is usually embedded in the PYTHONSTARTUP or PYTHONPATH directories to make switching module libraries easy. |
Mac Os Versions
Running Python
There are three different ways to start Python −
Interactive Interpreter
You can start Python from Unix, DOS, or any other system that provides you a command-line interpreter or shell window.
Enter python the command line.
Start coding right away in the interactive interpreter.
Here is the list of all the available command line options −
Sr.No. | Option & Description |
---|---|
1 | -d It provides debug output. |
2 | -O It generates optimized bytecode (resulting in .pyo files). |
3 | -S Do not run import site to look for Python paths on startup. |
4 | -v verbose output (detailed trace on import statements). |
5 | -X disable class-based built-in exceptions (just use strings); obsolete starting with version 1.6. |
6 | -c cmd run Python script sent in as cmd string |
7 | file run Python script from given file |
Script from the Command-line
A Python script can be executed at command line by invoking the interpreter on your application, as in the following −
Note − Be sure the file permission mode allows execution.
Integrated Development Environment
You can run Python from a Graphical User Interface (GUI) environment as well, if you have a GUI application on your system that supports Python.
Unix − IDLE is the very first Unix IDE for Python.
Windows − PythonWin is the first Windows interface for Python and is an IDE with a GUI.
Macintosh − The Macintosh version of Python along with the IDLE IDE is available from the main website, downloadable as either MacBinary or BinHex'd files.
If you are not able to set up the environment properly, then you can take help from your system admin. Make sure the Python environment is properly set up and working perfectly fine.
Note − All the examples given in subsequent chapters are executed with Python 2.4.3 version available on CentOS flavor of Linux.
We already have set up Python Programming environment online, so that you can execute all the available examples online at the same time when you are learning theory. Feel free to modify any example and execute it online.
Cybersearch.xyz is a nasty browser hijacker that affects the majority of popular browsers in Mac environment – Google Chrome, Mozilla Firefox and Safari.

Tips to delete cybersearch.xyz pop-ups manually.
How does your browser work when cybersearch.xyz pop-ups are enabled in it?
First of all, it is important to mention that cybersearch.xyz pop-ups may occur with all popular browsers, including Google Chrome, Opera, Mozilla Firefox, Internet Explorer and Microsoft Edge. Even Safari in Mac OS X is not an exception and can be vulnerable as well. You will definitely notice that your browser and your system in general will be functioning extremely slow as a result of cybersearch.xyz pop-ups enabled.
Cybersearch.xyz pop-ups have the intention to redirect your browser to plenty of other unsafe places in the world wide web. As a result, your home page may be hijacked, whereas the entire system may become infected with other potentially unwanted and even harmful programs. As a result, you may end up facing your computer to be permanently freezing and unable to satisfy your requirements.

It is true that cybersearch.xyz pop-ups represent danger for your entire computer. The problem is that they do not appear by themselves. There is always the reason why these alerts come up, and this is most likely explained by presence of some nasty adware in your system. We strongly advise that you continue reading this guide to find out about ways through which adware enters the systems and methods of its prevention in the future.
Channels through which cybersearch.xyz pop-ups become enabled in your browser.
It is a common practice for adware and related pop-up windows to penetrate into browsers using the software installation method called ‘bundling‘. There are certain free programs (both for Windows and Mac systems) which may be downloaded over various freeware download resources absolutely at no cost for you. As a price for downloading this free software, its installer may additionally contain other programs suggested to be installed by default. Hence, the installer of certain free application may also be interconnected with installers of other unwanted utilities, such as adware, browser hijackers, etc. If you ever deal with such cost-free applications, make sure you always select the option of a custom (advanced) installation to prevent any additional software from entering your system. Here is the screenshot which shows you how to decline installation of additional software while installing free applications:
Whenever people fail to be careful as described above, then end up installing plenty of other junk utilities which they do not need at all. In a hurry while installing those free programs, they may blindly click on Next or I agree buttons, without understanding much what they agree with.
Another reason why cybersearch.xyz pop-ups and associated adware got injected into your system is because of poorly updated databases of your available anti-virus software. You may have some security tool enabled, however, due to its outdated databases this software could miss certain malware intrusion attacks and thus permit cybersearch.xyz pop-ups to become the part of your browser. If this is so, it’s time for you to reconsider your existing anti-malware and rather give preference to some other program which definitely can protect your system. To fix this particular issue of cybersearch.xyz pop-ups, please follow this removal tutorial below.
