Python换行符长“x1作为y1，x2作为y2，x3作为y3”语句[重复]答案

【问题标题】：Python line break in long "with x1 as y1, x2 as y2, x3 as y3" statement [duplicate]Python换行符长“x1作为y1，x2作为y2，x3作为y3”语句[重复]

【问题描述】：

我想打破这样的长陈述：

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

但这是一个语法错误。似乎以下内容有效，但我觉得阅读起来相对困难：

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？谢谢。

【解决方案1】：

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

试试看。我认为将各个语句保持在一行中很重要。反斜杠有助于保持 Python 的显式 > 隐式风格。
