It's the same syntax as an import statement such as the following:
import numpy as np, matplotlib as mpl
A downside with this is the inability to split long lines by adding
parentheses. Obviously you can break at the open() call:
with open('old.dat') as fin, open(
'new.dat', 'w') as fout:
for line in fin:
But I think it's more readable to break up a long line like this:
fin = open('old.dat')
fout = open('new.dat', 'w')
with fin, fout:
for line in fin:
