Python的換行符 「以X1爲Y1，X2爲Y2，X3爲Y3」 聲明

Question

我想打破長的語句，如：

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

我曾嘗試：

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

但這是一個語法錯誤。看來，以下的作品，但我發現它比較難讀：

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

有沒有對如何最好地格式化長with聲明這樣有什麼建議？謝謝。

Answer 1

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

試試看。我認爲將個別陳述作爲一條線是重要的。反斜槓有助於保持Python的顯式>隱式樣式。
