# Project Euler: Problem 34

# 145 is a curious number, as 1! + 4! + 5! = 1 + 24 + 120 = 145.
#
# Find the sum of all numbers which are equal to the sum of the factorial of their digits.
#
# Note: as 1! = 1 and 2! = 2 are not sums they are not included.

To install virtualenv via pip
$ pip3 install virtualenv

Note that virtualenv installs to the python3 directory. For me it's:
$ /usr/local/share/python3/virtualenv

Create a virtualenvs directory to store all virtual environments
$ mkdir somewhere/virtualenvs

Make a new virtual environment with no packages
