- Beyond PEP 8 - Best Practices for Beautiful intelligible Code
- Raymond Hettinger
- worst thing about line length: Someone will pep-8 me.
- working around line length doesn't involve making the code better
- just shorten variable names : makes code worse
- 90-ish
- people with problems in the codebase tend to gravitate to pep8
- kind of a makework job
- pep-8 fixers obfuscate the history
- pep-8
- ends up with code that is beautiful but bad
- distracts you from what is important
- pep-8 unto yourself, not others
- use modules rather than packages if you can
- use context manager rather than try/except
- use types rather than building methods
- e.g. replace getter/setter into properties
- Beyond pep-8 - pay attention to what python is good at
- P vs NP problem
- pythonic vs non-pythonic
- "If your users are having to type a lot of dots in their code, you're doing it wrong"
- Adapter pattern
- transforms one API into another one
- custom exceptions
- repr's for readability
- properties rather than accessors
- use sane function/identifier names
- in python, you don't have to use keyword arguments, but you can (to make the function call more clear)
- namedtuples vs tuples without identifiers
- focus on clarity
How to make your code Python 2/3 compatible- Brett Cannon
- brett@python.org
- not about convincing
- pycon 2013 talk
- you can start today!
- dont wait for dependencies
- python3porting.com
- whats new document
- porting howto
- docs.python.org/3/howto/pyporting.html
- Learn to love 'six'
- compat library to smooth edges
- single module for easy vendoring
- pypi.python.org/pypi/six
- Only support 2.7
- 2.6 isn't even supported for bugs anymore
- good test coverage is critical
- so you don't break things when porting
- coverage.py is handy
- new file template
- # coding: utf-8
from __future__ import (absolute_import,
division, print_function, unicode_literals)
- transpilers do all the easy stuff
- modernize
- harnesses 2to3 to updating python code to work with python 2.6/3 as much as possible
- futurize
- modernize but with more of a python 3 feel
- provides backports of things from python3 such as bytes type
- part of the future project
- some fixes require thinking
- need to care about text vs binary data
- can't conflate the two anymore
- need to care bout text vs binary data apis
- unicode/str in python 2
- str/bytes in python3
- b prefix + unicode_literals future statement
- you should know what every string literal is (string vs bytes)
- if you're working with text
- make it work with unicode
- if working with binary data
- indexing with bytes returns an int
- str
- __mod__
- encode
- format
- isdecimal
- isnumeric
- bytes
- decode
- python 3.5 improvements
- bytes interpolation
- b'I %s bytes' % (b'love', )
- -b helps when comparing bytes to ints
- Division
- 5/2 = 2 in python2
- 2.5 in python3
- pylint
- --py3k flag to run only checks related to python3 compatibility
- python flags
- -3
- triggers warnings under python2
- -b
- under python3 to issue warnings about byte issues
- Dependencies

Advanced Git- David Baumgold
- @singingwolfboy
- bit.ly/git-pycon-2015
- basics
- clone, checkout, commit, push/pull
- status
- current state of repo
- git show
- show's the commit you're currently sitting on
- show's commit messages and diffs
- git blame
- git cherry-pick
- creates an entirely new commit off of a commit
- git reset
- reset the branch pointer
- git reset --hard HEAD^
- git reset with no args: pops off the commit, but doesn't change the disk contents, but allows you to recommit
- git reset --hard throws away the changes too
- symbolic branch locatons
- HEAD = commit I'm on
- HEAD^ = this commit's parent
- HEAD^^ = this commit's grandparent
- HEAD~5
- git rebase
- changes history
- warnings
- never change history when other people might be using your branch
- never change history on master
- moves a feature branch to another root on master using cherry pick
- while on a feature branch
- git rebase master
- git will reject the push if the branches diverged
- git push -f
- with a conflict
- resolve the conflict
- git rebase --continue
- or if you want to start over:
- git rebase --abort
- git reflog
- git log: shows history in ancestor order
- git reflog: shows history in time order
- git commit --amend
- update the last commit with additional changes
- interactive rebase
- user interface
- move pick to squash
- git rebase --interactive
- "did a bunch of things""
- move pick to edit
- git bisect
- the feature is broken? Was just fine!
- bisect helps you find where things broken
- needs
- test
- a commit where things were working
- a commit where things were not working
- git bisect start
- git checkout broken-commit
- git bisect broken
- gt checkout
- git bisect run my_test.sh

- Losing your Loops: Fast Numerical Computing with NumPy
- Using numpy effectivly to do data intensive computing
- Python is fast: for writing, testing and developing fast
- high leel, interpreted, dynamic typed language
- Python is slow
- repeated tasks
- python is around 1000x than fortran for tight loops of lots of repetitions
- what makes python fast for development makes it slow for execution
- solution, remove python loops
- 4 strategies for speeding up code with numpy
- ufuncs
- universal function
- operates elementwise on arrays
- a= [ 1, 3, 2, 5, ]
b = [x + 5 for x in a]
import numpy as np
a = np.array(a)
b = a + 5 # element-wise
print b - arithmetic operators
- bitwise
- comparision operators
- trig family
- special functions
- aggregations
- aggregations are functions which summarize an array
- e.g. min, max, sum, mean, etc
- numpy is much faster than python builtins
- can work on multidimensional arrays
- M.sum(axis=)
- min, max, sum, prod, mean, std, variance, any, all, median, percentile, argmin, argmax, nanmin, nanmax, nansum (ignores not-a-number)
- broadcasting
- set of rules which ufuncs apply to a numpy object
- rules
- if array shapes differ, left-pad the smaller shape with 1s
- dimension does not match broadcast the dimension with size=1
- adding a scalar to a vector
- np.arange(3) - 5
- slicing, masking, fancy indexing
- lists are indexed by integers for single value
- indexed by slices for multiple values
- np.array have similar indexes, plus
- more indexing (fast)
- masking
- A = array([2,3,5,7,11])
- mask = np.array([False, True, True, False, True])
- A[mask]
- fancy indexing
- A
- index = [0, 4, 2]
- A[index]
- computing nearest neighbor
- D2 = (xi - xj)2 + (yi - yj)2
x = np.random((1000 3))
X.shape
(1000,3)

- Keeps people out of tech

- Guido van Rossum: Gradual Typing for Python 3
- Guido van Rossum
- Ancient History
- 2000: types-sig
- optional static typing talk
- type hint annotations
- 2004-2005
- artima blogs on optional static typing
- generic types
- 2006
- PEP3107: function annotations
- compromise: annotation syntax but no semantics
- 2013
- Met Jukka Lehtosalo (mypy) at PyCon
- convinced to make mypy
- 2014
- What python can learn from haskell
- mypy
- 2015
- PEP 484: type hints
- proposal
- static type checker a seperate program
- closer to a lint tool than an interpretter
- function annotations for inline type hints
- stub files to annotate code you cannot change
- why
- find bugs sooner
- the larger your project, the more you need it
- helps spelunking code
- large teams are already static analysis
- google, dropbox building their own
- also products like semmle
- type hints
- help the type checker
- in dynamic python, flow of objects is hard to follow
- serve as additional documentation
- help ides
- improve suggestions
- improve interactive code checks
- why stubs
- py2 compatibility
- C extensions
- author unwilling to do it
- why a duck
- why a pep
- let the use mypy if they want to
- standard notation helps everyone
- code generation
- not high on the prio list
- cython might be able to use them
- pypy and others have done fine without the type hints
- Type hints outline
- basics
- gradual typing
- some code can be annotated, other nt
- Abscence of type info is roughly approximate to Any
- Any is at the top and bottom of class tree
- Any is a superclass of everything
- Any is a subclass of everything too
- typing.py
- only real change
- no new syntax
- no changes to other stdlib module
- from typing import Any, List
- annotations
