Python 2.7.3 was released on April 9, 2012. 2.7.3 includes fixes for severalreported security issues in 2.7.2: issue 13703 (oCERT-2011-003, hashcollision denial of service), issue 14234 (CVE-2012-0876, hash tablecollisions CPU usage DoS in the expat library), issue 14001 (CVE-2012-0845,SimpleXMLRPCServer denial of service), and issue 13885 (CVE-2011-3389,disabling of the CBC IV attack countermeasure in the _ssl module).
The Python 2.7 series is scheduled to be the last major version in the 2.xseries before 2.x moves into an extended maintenance period. The 2.7 seriescontains many of the features that were first released in Python 3.1.Improvements in this release include:
- An ordered dictionary type
- New unittest features including test skipping, new assert methods, and testdiscovery
- A much faster io module
- Automatic numbering of fields in the str.format() method
- Float repr improvements backported from 3.x
- Tile support for Tkinter
- A backport of the memoryview object from 3.x
- Set literals
- Set and dictionary comprehensions
- Dictionary views
- New syntax for nested with statements
- The sysconfig module

[1] | (1, 2) The binaries for AMD64 will also work on processors that implement the Intel 64 architecture (formerly EM64T), i.e. the architecture that Microsoft calls x64, and AMD called x86-64 before calling it AMD64. They will not work on Intel Itanium Processors (formerly IA-64). |
[2] | (1, 2) There is important information about IDLE, Tkinter, and Tcl/Tk on Mac OSX here. Also, on Mac OS X 10.6, if you need tobuild C extension modules with the 32-bit-only Python installed, you willneed Apple Xcode 3, not 4. The 64-bit/32-bit Python can use eitherXcode 3 or Xcode 4. |

Features
Easy to get started. Thonny comes with Python 3.7 built in, so just one simple installer is needed and you're ready to learn programming. (You can also use a separate Python installation, if necessary.) The initial user interface is stripped of all features that may distract beginners. |
No-hassle variables. Once you're done with hello-worlds, select View → Variables and see how your programs and shell commands affect Python variables. https://exelin.hatenablog.com/entry/2020/11/22/090341. |
Simple debugger. Just press Ctrl+F5 instead of F5 and you can run your programs step-by-step, no breakpoints needed. Press F6 for a big step and F7 for a small step. Steps follow program structure, not just code lines. |
Step through expression evaluation. If you use small steps, then you can even see how Python evaluates your expressions. You can think of this light-blue box as a piece of paper where Python replaces subexpressions with their values, piece-by-piece. |
Faithful representation of function calls. Stepping into a function call opens a new window with separate local variables table and code pointer. Good understanding of how function calls work is especially important for understanding recursion. |
Highlights syntax errors. Unclosed quotes and parentheses are the most common beginners' syntax errors. Thonny's editor makes these easy to spot. |
Explains scopes. Highlighting variable occurrences reminds you that the same name doesn't always mean the same variable and helps spotting typos. Local variables are visually distinguished from globals. |
Mode for explaining references. Variables are initially presented according to simplified model (name → value) but you can switch to more realistic model (name → address/id → value). |
Code completion. https://ewtvacb.weebly.com/serial-key-para-office-2016.html. https://Mac-Book-Pdf-App.peatix.com/. Students can explore APIs with the help of code completion. |
Beginner friendly system shell. Select Tools → Open system shell to install extra packages or learn handling Python on command line. PATH and conflicts with other Python interpreters are taken care of by Thonny. |
Simple and clean pip GUI. Select Tools → Manage packages for even easier installation of 3rd party packages. |
