Ways to run Python


  • default configuration (python2.7):

is normally going to run python2.7, linked like this /usr/bin/python2.7@ → ../../System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 when using this native version of python, some dependences might run into permission problems and thus installing modules via pip requires an extra flag “–user” which installs it only for the current users

  • pyhton3: osx comes with python3 installed, which can be called with
$ python3 
  • conda is a package and environment management system for Python, R, Node.js, Java and other application stacks.

Install conda for the system and version of choice. On OSX also run:

export PATH="$HOME/anaconda3/bin:$PATH"

Create an environment (-n name) using a specified python version

conda create -n myenv python=3.4

On managing (python) environments with conda:

  • virualenv is a python module installed using
pip install --user virtualenv
virtualenv --python python3 env
source env/bin/activate

some instructions:

  • docker
docker run -it -p 8888:8888 -p 6006:6006 -v sharedfolder:/root/sharedfolder floydhub/dl-docker:cpu bash
root@4aa86b7ed9d6:~# jypiter notebook
bash: jypiter: command not found
root@4aa86b7ed9d6:~# jupyter notebook

ipython goodies

run any shell command starting with %

for example, list files by size, or move a file to another location:

%ls -lhS
%mv a_file.extension newlocation/ 

load in an external .py file:


and call any function defined in it.
