import sys
print(sys.version)
print(sys.platform)
print(sys.getdefaultencoding() # NB this is a function not a variable
print(sys.executable)
import os
print(os.getcwd())
print(os.environ)

Note

Python built-in modules tend to use the word get___() to indicate that this is a function rather than an attribute. That might be a good thing to do in your own functions?

import numpy as np
print(np.random.random([2,3]))
print(np.random.randint(5,11)) #NB the high-end of the interval is non-inclusive :-/
#or
print(round(np.random.random()*5+5))
