If you want to do it manually, you can check out step number 3 for reference. Select Customize installation. This makes it easier to start Python Install for all users. Click Next. This takes us to Advanced Options available while installing Python.
Here, select the Install for all users and Add Python to environment variables checkboxes. Optionally, we can select the Associate files with Python, Create shortcuts for installed applications and other advanced options. Make a note of the python installation directory displayed in this step.
You would need it for the next step. After selecting the Advanced options, click Install to start the installation. The last optional step in the installation process is to add Python Path to the System Environment variables. This step is done to access Python through the command line. In case we have tick marked the option of Add to Path, then this step is not to be followed; you can avoid this step. Else, this step is done manually as follows. Locate the Python installation directory on your system.
If you followed the steps exactly as above, python will be installed in the below locations:. Look for a folder whose name starts with Python. Add the following entries to the PATH variable, as shown below:. We have now successfully installed Python 3. We can verify if the Python installation is successful or not through the command line or the IDLE app installed along with the installation.
Removed some debugging prints. Includes xml. Does not provide the HTML-specific extensions. Still undocumented. Some documentation is already available. A wrapper API was added for signal and sigaction. It is now officially useless but preserved for backwards compatibility. See note on getattr above. A few bug fixes to argument processing for Unicode.
Internals On Unix, fix code for finding Python installation directory so that it works when argv[0] is a relative path.
Several of the internal Unicode tables are much smaller now, and the source code should be much friendlier to weaker compilers. In the garbage collector: Fixed bug in collection of tuples. Fixed bug that caused some instances to be removed from the container set while they were still live. Fixed parsing in gc.
On Windows, getpythonregpath is now protected against null data in registry key. On Unix, create. Changes for the benefit of SunOS 4. Added missing prototypes in posixmodule. Improved support for HP-UX build. Threads should now be correctly configured on HP-UX IDLE: Move hackery of sys. Source Incompatibilities None. Note that 1. Binary Incompatibilities Third party extensions built for Python 1.
On Windows, attempting to import a third party extension built for Python 1. Overview of Changes Since 1. Lots of bugs have been fixed. The process for making major new changes to the language has changed since Python 1.
There are several important syntax enhancements, described in more detail below: Augmented assignment, e. A PEP is a design document providing information to the Python community, or describing a new feature for Python. The PEP should provide a concise technical specification of the feature and a rationale for the feature.
We intend PEPs to be the primary mechanisms for proposing new features, for collecting community input on an issue, and for documenting the design decisions that have gone into Python. The PEP author is responsible for building consensus within the community and documenting dissenting opinions. The PEPs are available here. Augmented Assignment This must have been the most-requested feature of the past years! However, if A is a mutable object, A may be modified in place. Classes and built-in object types can override the new operators in order to implement the in-place behavior; the not-in-place behavior is used automatically as a fallback when an object doesn’t implement the in-place behavior.
For classes, the method name is derived from the method name for the corresponding not-in-place operator by inserting an ‘i’ in front of the name, e. Augmented assignment was implemented by Thomas Wouters. List Comprehensions This is a flexible new notation for lists whose elements are computed from another list or lists.
This is more efficient than a for loop with a list. This is more efficient than a for loop with an if statement and a list. You can also have nested for loops and more than one ‘if’ clause. For example, here’s a function that flattens a sequence of sequences:: def flatten seq : return [x for subseq in seq for x in subseq] flatten [[0], [1,2,3], [4,5], [6,7,8,9], []] This prints [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] List comprehensions originated as a patch set from Greg Ewing; Skip Montanaro and Thomas Wouters also contributed.
Described by PEP Extended Import Statement Many people have asked for a way to import a module under a different name. A simple extension of the import statement now allows this to be written as follows: import foo as bar There’s also a variant for ‘from Implemented by Thomas Wouters.
Extended Print Statement Easily the most controversial new feature, this extension to the print statement adds an option to make the output go to a different file than the default sys. For example, to write an error message to sys. Optional Collection of Cyclical Garbage Python is now equipped with a garbage collector that can hunt down cyclical references between Python objects.
It’s no replacement for reference counting; in fact, it depends on the reference counts being correct, and decides that a set of objects belong to a cycle if all their reference counts can be accounted for from their references to each other. This devious scheme was first proposed by Eric Tiedemann, and brought to implementation by Neil Schemenauer.
There’s a module “gc” that lets you control some parameters of the garbage collection. There’s also an option to the configure script that lets you enable or disable the garbage collection. There are some questions about its performance. If it proves to be too much of a problem, we’ll turn it off by default in the final 2.
Smaller Changes A new function zip was added. When the lists are not all the same length, the shortest list wins: zip [1,2,3], [10,20] returns [ 1,10 , 2,20 ]. See PEP Dictionaries have an odd new method, setdefault key, default. Thus: dict. This limited the size of object constructor expressions, e. This limit was raised thanks to a patch by Charles Waldman that effectively fixes the problem. It is now much more likely that you will be limited by available memory than by an arbitrary limit in Python.
The interpreter’s maximum recursion depth can be modified by Python programs using sys. This limit is the maximum number of recursive calls that can be made by Python code. The limit exists to prevent infinite recursion from overflowing the C stack and causing a core dump. The default value is New Modules and Packages atexit – for registering functions to be called when Python exits. Describing these would fill a volume. Also new symbolic constants for days of week, e.
They allow the module to be used for writing config files as well as reading them. See the module doc strings for details. The readline section of the library reference manual contains an example. Tkinter – optimization of function flatten urllib – scans environment variables for proxy configuration, e.
However note that 1. Changed, New, Obsolete Tools None. C-level Changes Several cleanup jobs were carried out throughout the source code.
Most of the portability hacks were moved to a new header file, pyport. Few of these ever need to be included explicitly; they are all included by Python. Trent Mick ensured portability to bit platforms, under both Linux and Win64, especially for the new Intel Itanium processor. Mick also added large file support for Linux64 and Win The old names, e.
It prevents Python from failing with a stack overflow on Windows. The augmented assignment changes result in the creation of a new slot for each in-place operator. This change prevents crashes caused by programmer error. See Microsoft Knowledge Base article Q The Win9x workaround described there is implemented by the new w9xpopen. Note that Python uses this internally; it is not a standalone program.

You do not need to install or configure anything else to use Python. Having said that, I would strongly recommend that you install the tools and libraries described in the next section before you start building Python applications for real-world use. In particular, you should always install Setuptools, as it makes it much easier for you to use other third-party Python libraries. The two most crucial third-party Python packages are setuptools and pip. Once installed, you can download, install and uninstall any compliant Python software product with a single command.
It also enables you to add this network installation capability to your own Python software with very little work. To install pip, follow the official pip installation guide – this will automatically install the latest version of setuptools. We are extremely pleased to announce the release of Python 2. Our thanks to everyone who has contributed to the Python 2. You know who you are! Download the release Windows users should download Python EXE from Wise that fixes a bug which could cause the uninstaller to disappear in some circumstances.
EXE unless you chose a different directory at install time. Macintosh users can find Python 2. This is sometimes one or two releases behind, so be patient. Licenses All Python releases are Open Source.
Sources For most Unix systems, you must download and compile the source code. Alternative Implementations This site hosts the “traditional” implementation of Python nicknamed CPython.
Release Schedules Python 3. Release files for currently supported releases are signed by the following: Thomas Wouters 3. To verify the authenticity of the download, grab both files and then run this command: gpg –verify Python These instructions are geared to GnuPG and Unix command-line users.
