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.
