I prefer the optional-indentation syntax. The reason is simple (see my
discussion with Andrew), most of the time the indentation is useless,
even if you don't have multiple with-statements. So in my day-to-day
work, I would prefer to write:
def getFirstLine(filename):
with opening(filename) as file
return file.readline()
than:
def getFirstLine(filename):
with opening(filename) as file:
return file.readline()
But I agree that in the case of only one with-statement, that's no big deal.
Also, if multiple with-statements are separated by other indentating
statements, your proposal doesn't help:
with locking(lock)
if condition:
with opening(filename) as file
for line in file:
...
would still be needed to be written:
with locking(lock):
if condition:
with opening(filename) as file:
for line in file:
...
