source projects. As every C++ programmer knows, the language has many powerful features, but this power brings with it complexity, which in turn can make code more bug-prone and harder to read and maintain conflicts in large programs while allowing most code to use reasonably short names. For example, if two different projects have a class Foo in the global scope, these symbols may collide at compile time all the data and operations that the parent base class defines. In practice, inheritance is used in two major ways in C++: implementation inheritance, in which actual code is inherited by the child, and

evaluations Deprecated Language Features Lexical Scoping Function and Method Decorators Threading Power Features 1 Python Style Rules Semicolons Line length Parentheses Indentation Blank Lines Whitespace where x is the package prefix and y is the module name 3 with no prefix. Use from x import y as z if two modules named y are to be imported or if y is an inconveniently long name. For example the module Raise exceptions like this: raise MyException('Error message') or raise MyException. Do not use the two-argument form (raise MyException, 'Error message') or deprecated string-based exceptions (raise 'Error

Google Style, they may not illustrate the only stylish way to represent the code. Optional formatting choices made in examples should not be enforced as rules. 1 2 Source file basics 2.1 File name The source single block. If there are both static and non-static imports, a single blank line separates the two blocks. There are no other blank lines between import statements. Within each block the imported names indentation: +2 spaces Each time a new block or block-like construct is opened, the indent increases by two spaces. When the block ends, the indent returns to the previous indent level. The indent level applies

variableName), FunctionName, kConstantName 3. Line Length: maximum 80 characters 4. Indentation: two spaces, no tabs 5. Spacing 6. Curly Braces: first on same line, last on own line 7. else: Surround Ordering 11. Commenting Guidelines: all comments begin with # followed by a space; inline comments need two spaces before the # 12. Function Definitions and Calls 13. Function Documentation 14. Example Function Line Length The maximum line length is 80 characters. Indentation When indenting your code, use two spaces. Never use tabs or mix tabs and spaces. Exception: When a line break occurs inside parentheses
