2.1 Python Coding Conventions

Follow the standard Python formatting rules when writing code for Sage, as explained at http://www.python.org/dev/peps/pep-0008/ and http://www.python.org/dev/peps/pep-0257/. In particular,

Use 4 spaces for indentation levels. Do not use tabs as they can result in indentation confusion. Most editors have a feature that will insert 4 spaces when the tab key is hit. Also, many editors will automatically search/replace leading tabs with 4 spaces.
Usually use all lowercase function names with words separated by underscores:
```
        def set_some_value()
```
instead of CamelCase:
```
        def SetSomeValue()
```
Use CamelCase for class names and major functions that create objects, e.g., PolynomialRing.

Note however that some functions do have uppercase letters where it makes sense. For instance, the function for lattice reduction by the LLL algorithm is called Matrix_integer_dense.LLL.
