Sometimes you want to save a dictionary into a reusable file, and reuse it later. This is specifically useful when you need to save a color scheme for a large category and want to keep it consistent across your whole project.

Output it as a file:

import pickle

colorDicOut = open('colorOut_dic.pkl', 'wb')
pickle.dump(colorDic, colorDicOut)
colorDicOut.close()

with open('colorOut_dic.pkl', 'wb') as colorDicOut:
    pickle.dump(colorDic, colorDicOut)

Load it into a variable:

colorDicIn = open("colorOut_dic.pkl","rb")
colorDic = pickle.load(colorDicIn)

If UnicodeDecodeError comes up, then it is likely an issue of incompatibility between python2 and python3, please refer to this post for solutions.
