Python Guide on Code Style and CodeSkulptor Features

Code style is important for readability and debugging of programs, and consistency with other programmers.
CodeSkulptor is a browser-based Python interpreter that supports a subset of Python 2 and three graphical libraries.
Compound statements can be built from smaller statements, while simple statements cannot contain other statements.
Hashable values are immutable and can be converted into an integer using a hash function.
CodeSkulptor supports only "classic" or "old-style" classes, instance methods, and not new-style classes, class methods, or static methods.
All values in Python are objects, and objects can have attributes, including methods.
Mutable types have operations that mutate or update part of the value, while immutable types do not.
CodeSkulptor does not support several features of Python, including complex numbers, Unicode strings, and memory view objects.
The max() and min() functions return the maximum and minimum values in an iterable or multiple arguments.
The slice() function returns a new sequence of items in a given sequence, starting from an index and incrementing by a step.
Generators are a type of iterator that use the yield keyword instead of return, and can represent an infinite number of elements.
Anonymous functions are simplified forms of function definitions without a name, parameter list in parentheses, and a single expression as the function body.Python Built-in Functions Summary
Python has many built-in functions for manipulating sets, dictionaries, tuples, lists, strings, numbers, and Booleans.
Set functions include set difference, intersection, union, symmetric difference, difference update, intersection update, and union update.
The set type is an unordered collection without duplicates, commonly used to loop over all values in a dictionary.
Dictionary functions include getting, setting, removing, checking for existence, and creating dictionaries from iterables.
The dictionary type is an unordered collection of key-value pairs, commonly used as associative memories or hashmaps.
Tuple functions include conversion to a tuple, sorting, and item assignment.
The tuple type is an immutable sequence of values of any type.
List functions include sorting, item removal, item insertion, concatenation, arithmetic progression, and conversion to a list.
The list type is a mutable sequence of values of any type.
String functions include stripping, alignment, digit checking, word splitting, partitioning, finding, replacing, case conversion, concatenation, and representation.
The string type is an immutable sequence of characters.
Boolean functions include all, any, or, and, not, and truth testing. Booleans represent the logical truth values True and False and can be used anywhere that numbers can.CodeSkulptor Library Summary
CodeSkulptor implements a subset of the Python standard library.
The math module contains additional mathematical operations.
The random module contains functions that involve randomness.
The re module allows use of regular expressions.
The collections module includes a counter and default dictionary.
The time module includes operations that measure the passage of time.
The urllib2 module contains functions for obtaining input data from the web.
The None object is known as the null object and serves as a placeholder return value.
The int() and long() functions return the integer part of a number or string.
The float() function returns a number from a string, including special cases for infinity.
SimplePlot provides functions for plotting numeric data.
SimpleMap provides an interface for drawing and annotating maps with markers and paths.CodeSkulptor: A Browser-based Python Programming Environment
CodeSkulptor is a browser-based programming environment for Python.
It was created in 2012 for teaching Python programming, especially to beginners.
CodeSkulptor runs in Google Chrome 18+, Mozilla Firefox 11+, and Apple Safari 6+.
There are multiple versions of CodeSkulptor: CodeSkulptor runs Python 2 and CodeSkulptor3 runs Python 3.
The SimpleGUI module is for building interactive programs and drawing.
The SimpleMap module is for drawing features on maps.
The SimplePlot module is for plotting numeric data.
CodeSkulptor provides a control panel on the left and a canvas on the right for building interactive programs.
CodeSkulptor imposes a timeout on all programs to prevent them from running forever and locking up the browser.
CodeSkulptor has buttons for Run, Save, Download, Fresh URL, Open Local, and Reset.
CodeSkulptor offers links to useful resources such as documentation, example Python programs, and a popular MOOC.
CodeSkulptor has a console for displaying printed output and error messages.
