I am using MacOS X 10.7.5 and am a TOTAL newb at Python
I am pretty sure django installed correctly as per https://code.djangoproject.com/wiki/Distributions

The issue was with that a prior Python was installed (2.7.1) previously and MacPorts installed a new one (2.7.6) but did not update the Mac Sym links etc
So I had to futz with my PATH
$ vi ~/.bash_profile
.
.
export PATH=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin:$PATH
.
.
$ source ~/.bash_profile
$ python --version

Actually I already installed tensorflow by using
$ pip install tensorflow
and it works well when I use
$ python

but when I use python3 on command line

>>> import tensorflow

it shows an error, and it shows the same error when I use IDLE
use
pip3 install tensorflow
pip installs to default python directory. pip3 installs to python3
Have both versions of Python (Legacy 2.7.10 and 3.6.2) installed on macOS Sierra.
Installed pip using the following steps.
Downloaded it using curl:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
Installed pip it by running the installer script:
sudo python get-pip.py
Checked for any upgrades / updates for pip:
sudo pip install -U pip
Installed django 1.11:
sudo pip install django==1.11
When I run python (legacy):
python
Python 2.7.10 (default, Feb 7 2017, 00:08:15)

Type "help", "copyright", "credits" or "license" for more information.
>>> import django
>>> print(django.get_version())
1.11
However, when trying it using python3:

Traceback (most recent call last):

ModuleNotFoundError: No module named 'django'
Note: I followed a different tutorial and got python3 working with django 1.11 using virtualenv - please don't suggest this as I am new to the python world and just want to use python3 / django 1.11 in a non-virtual environment - I just want have it working like the legacy python interpreter is behaving.
pip installs libraries differently for python2 and python3, so you effectively have different environments for each. If you want to install Django for python3, you'll want to install it like this:
pip3 install django==1.11
I try to visualize graph with matplotlib in python but I have few problem in my mac (Yosemite 10.10.2). I already installed matplotlib, and I know that I have 2 version of python installed in my computer, which are 2.7.8 and 2.7.6
Using default interpreter which is python 2.7.8, I got this error
dhcPlus-mbp:~ macbook$ python
Python 2.7.8 (v2.7.8:ee879c0ffa11, Jun 29 2014, 21:07:35)

>>> import matplotlib
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named matplotlib
But if I try this one, it works on terminal. But I can't build straight from my Sublime with Ctrl+B
dhcPlus-mbp:~ macbook$ /usr/bin/python

My question is, how could I change default python interpreter so I can use the 2.7.6 in my environment?
Any help is greatly appreciated. Thank you very much.
This problem solved by removing the extra Python libraries on Mavericks by
sudo rm -rf /Library/Frameworks/Python.framework/
I have python installed in two locations, in os default it's 2.6.6 and in /usr/local/bin/python2.7 has 2.7.
I have installed cairo (cairo-1.12.18) via source using configure/make/make install, but it appears to have installed under python 2.6.6. How do I install it for python2.7?

Thank you.
Be sure to install it using python 2.7 and not python 2.6 (run make and make install using python 2.7). I assume you use Linux OS so your default Python is 2.7, you can change your default Python but it's not recommended due to several reasons. Please look at this StackOverflow question and answers for more informations:
Two versions of python on linux. how to make 2.7 the default
I've installed Python 3.3 alongside Python 2.75 on my Ubuntu machine. The problem is that easy_install gets packages for the default, 2.75 version only, e.g:
easy_install pymongo
$ python
Python 2.7.4 (default, Apr 19 2013, 18:28:01)
[GCC 4.7.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pymongo
>>>
But:
$ python3.3
Python 3.3.1 (default, Apr 17 2013, 22:30:32)
[GCC 4.7.3] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pymongo
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'pymongo'
How can I install PyPi packages for the Python 3.3 installation?
You need easy_install3. In apt-get you get it by
apt-get install python3-setuptools
