Question

我想打破一个长篇陈述，如：

with X1() as y1, X2() as y2, X3() as y3:  # Really long line
  # Do something

我试过了：

with (
    X1() as y1,
    X2() as y2,
    X3() as y3):
  # Do something

但这是语法错误。似乎以下工作，但我发现它相对难以阅读：

with X1(
    ) as y1, X2(
    ) as y2, X3(
    ) as y3:
  # Do something

对于如何最好地格式化这样的长with语句，有什么建议吗？感谢。

Answer 1

with X1() as y1, \
    X2() as y2, \
    X3() as y3:

试试吧。我认为将个别陈述保持为一行非常重要。反斜杠有助于保持明确的＆gt;隐式的Python风格。
