Python finally 关键字

实例

无论 try 块是否引发错误，都将始终执行 finally 块：

try:
  x > 3
except:
  print("Something went wrong")
else:
  print("Nothing went wrong")
finally:
  print("The try...except block is finished")

finally 关键字在 try ... except 块中使用。它定义了一个代码块，当 try...except...else 块结束时，该代码块将运行。

无论 try 块是否引发错误，都将执行 finally 块。

这对于关闭对象和清理资源很有用。
