Information about specific ports, and developer info

OpenPGP Public Keys

Source and binary executables are signed by the release manager or binary builder using their OpenPGP key. Release files for currently supported releases are signed by the following:

Release files for older releases which have now reached end-of-life may have been signed by one of the following:

You can import a person's public keys from a public keyserver network server you trust by running a command like:

or, in many cases, public keys can also be found at keybase.io. On the version-specific download pages, you should see a link to both the downloadable file and a detached signature file. To verify the authenticity of the download, grab both files and then run this command:

gpg --verify Python-3.6.2.tgz.asc

Note that you must use the name of the signature file, and you should use the one that's appropriate to the download you're verifying.

(These instructions are geared to GnuPG and Unix command-line users.)

macOS Installer Packages

Installer packages for Python on macOS downloadable from python.org are signed with with an Apple Developer ID Installer certificate.

As of Python 3.11.4 and 3.12.0b1 (2023-05-23), release installer packages are signed with certificates issued to the Python Software Foundation (Apple Developer ID BMM5U3QVKW)).

Installer packages for previous releases were signed with certificates issued to Ned Deily (DJ3H93M7VJ).

Other Useful Items

Looking for 3rd party Python modules? ThePackage Index has many of them.

You can view the standard documentation online, or you candownload it in HTML, PostScript, PDF and other formats. See the mainDocumentation page.

Information on tools for unpacking archive files provided on python.org is available.

Tip: even if you download a ready-made binary for your platform, it makes sense to also download thesource. This lets you browse the standard library (the subdirectoryLib) and the standard collections of demos (Demo) and tools (Tools) that come with it. There's a lot you can learn from the source!

There is also a collection of Emacs packages that the Emacsing Pythoneer might find useful. This includes major modes for editing Python, C, C++, Java, etc., Python debugger interfaces and more. Most packages are compatible with Emacs and XEmacs.

Python, which was initially developed by Guido van Rossum and made available to the public in 1991, is currently one of the most widely used general-purpose programming languages. Python's source code is freely available to the public, and its usage and distribution are unrestricted, including for commercial purposes. It is widely used for web development, and using it, practically anything can be created, including mobile apps, online apps, tools, data analytics, machine learning, and so on. It is intended to be straightforward and uncomplicated, much like the English language. When compared to other programming languages such as C++, Java, and C#, it is a lot simpler to read and write Python programs. Because of its excellent productivity and efficiency, it has become a very popular choice for use as a programming language.

To learn more about Python check out some of the following links.

Python is a simple language to pick up. It has a simple syntax, and the code is quite easy to read.

Python is useful in a wide variety of contexts. It is put to use in the creation of quick application development, data science, Internet of Things, and web applications, among other things.

When compared to most other programming languages, it enables you to develop applications using a smaller number of lines of code.

It has a very huge community behind it, and there are active forums for users to participate in.

The presence of Third Party Modules contributes to the increased power of the Python programming language.

The user is able to easily solve difficult problems with the help of extensive support libraries (for example, NumPy, which is used for numerical computations and Pandas, which is used for data analytics).

It includes extremely user-friendly data structures, which simplify both the design of the code and the reasoning behind it.

The number of people using Python is constantly on the rise. It has quickly become one of the most widely used programming languages.

Design that is Uncomplicated and Sparse, along with Being Lightweight, Easy, and Quick to Use

Version 3.8 of Python is supported for interactive program execution, which requires the user to provide inputs to the program in real time.

Options for a dark and light theme, as well as a customised code editor with additional themes, are helpful for novices learning and practising Python.

Options to Undo or Redo Changes Made in the Code Editor Options to Copy or Download the Results of the Program Expandable Output Terminal Options to Undo or Redo Changes

A hint for the frequently occurring problems in Python

Interactive Python Shell Advanced Python module support relevant to Data Science, including Pandas and NumPy Coding sharing functionality allows you to save your code in the cloud, where it can be retrieved whenever and wherever there is internet connectivity.

Built-in Data Types

In programming, data type is an important concept.

Variables can store data of different types, and different types can do different things.

Python has the following data types built-in by default, in these categories:

Getting the Data Type

You can get the data type of any object by using the type() function:

Setting the Data Type

In Python, the data type is set when you assign a value to a variable:

Setting the Specific Data Type

If you want to specify the data type, you can use the following constructor functions:

Python Conditions and If statements

Python supports the usual logical conditions from mathematics:

These conditions can be used in several ways, most commonly in "if statements" and loops.

An "if statement" is written by using the if keyword.

Example

If statement:

Try it Yourself "

In this example we use two variables, a and b, which are used as part of the if statement to test whether b is greater than a. As a is 33, and b is 200, we know that 200 is greater than 33, and so we print to screen that "b is greater than a".

Indentation

Python relies on indentation (whitespace at the beginning of a line) to define scope in the code. Other programming languages often use curly-brackets for this purpose.

Example

If statement, without indentation (will raise an error):

Try it Yourself "

Elif

The elif keyword is Python's way of saying "if the previous conditions were not true, then try this condition".

Example

Try it Yourself "

In this example a is equal to b, so the first condition is not true, but the elif condition is true, so we print to screen that "a and b are equal".

Else

The else keyword catches anything which isn't caught by the preceding conditions.

Example

Try it Yourself "

In this example a is greater than b, so the first condition is not true, also the elif condition is not true, so we go to the else condition and print to screen that "a is greater than b".

You can also have an else without the elif:

Example

Try it Yourself "

Short Hand If

If you have only one statement to execute, you can put it on the same line as the if statement.

Example

One line if statement:

Try it Yourself "

Short Hand If ... Else

If you have only one statement to execute, one for if, and one for else, you can put it all on the same line:

Example

One line if else statement:

Try it Yourself "

This technique is known as Ternary Operators, or Conditional Expressions.

You can also have multiple else statements on the same line:

Example

One line if else statement, with 3 conditions:

Try it Yourself "

And

The and keyword is a logical operator, and is used to combine conditional statements:

Example

Test if a is greater than b, AND if c is greater than a:

Try it Yourself "

Or

The or keyword is a logical operator, and is used to combine conditional statements:

Example

Test if a is greater than b, OR if a is greater than c:

Try it Yourself "

Not

The not keyword is a logical operator, and is used to reverse the result of the conditional statement:

Example

Test if a is NOT greater than b:

Try it Yourself "

Nested If

You can have if statements inside if statements, this is called nested if statements.

Example

x = 41

Try it Yourself "

The pass Statement

if statements cannot be empty, but if you for some reason have an if statement with no content, put in the pass statement to avoid getting an error.
