# You need something to pickle first.
# You could call it "self", but that is confusing
# as this name is by convention used inside methods as
# the current instance. So:
p = Pickle(1, 2, 3)

# Don't touch the object's attributes,
# pickle the whole instance instead:
pickle.dump(p, f)
> with open('/tmp/readfile.pkl', 'rb') as f:
# Load the instance back from file
p = pickle.load(f)
# print it
print p.PM1
print p.PM2
print p.PM3
