[Python] 개발환경 구축

https://www.python.org/

• PyCharm IDE Download (https://www.jetbrains.com/pycharm/download/#section=windows)
• Wingware Pythone IDE Pro (http://wingware.com/)
• Python documentation (https://docs.python.org/3/)
• Python built-in functions (https://docs.python.org/3/library/functions.html)

Installation

Windows

1. Download both Python2 and Python3 (https://www.python.org/downloads/)
2. Install by executing *.msi files
3. Copy C:\Python27\python.exe with the name python2.exe
4. Copy C:\Python34\python.exe with the name python3.exe
5. Add Environment Variables
   1) Go to System Variables
   2) Add new variables (PYTHON2_HOME: C:\Python27, PYTHON3_HOME: C:\Python34)
   3) Add two variables to the end of 'path': %PYTHON2_HOME%;%PYTHON3_HOME%;
6. Version check
   

   C:\Users\ChangUk> python -V
   Python 2.7.10
   C:\Users\ChangUk> python3 -V
   Python 3.4.3

Linux (Ubuntu)

1. Run the following command:
   

   $ sudo apt-get install python
   $ sudo apt-get install python3

2. Version check
   

   $ python -V
   Python 2.7.6
   $ python3 -V
   Python 3.4.0

Install pip

Windows

1. Download pip-get.py file from here
2. Run the command:
   

   C:\Users\ChangUk> python get-pip.py

Linux (Ubuntu)

Install pip:

$ sudo apt-get install python-pip python-dev build-essential 
$ sudo pip install --upgrade pip 
$ sudo pip install --upgrade virtualenv

Install pip for Python3:

$ sudo apt-get install python3-pip
$ sudo pip2 install MODULE_NAME
$ sudo pip3 install MODULE_NAME

만약 pip3로 설치를 진행하려다 'ImportError: cannot import name IncompleteRead' 에러가 발생한다면 pip를 최신 버전으로 업그레이드 해주면 된다. 버전 차이로 인한 문제이다.

$ easy_install -U pip
