• To ensure some code runs no matter what errors occur, you can use a finally statement.
  • 어떤 에러가 발생하더라도 일부 코드가 실행되도록 하기 위해 finally 문을 사용할 수 있다.
• The finally statement is placed at the bottom of a try/except statement.
  • finally 문은 try/except 문의 맨 아래에 위치한다.
• Code within a finally statement always runs after execution of the code in the try, and possibly in the except, blocks.
  • finally 문 내의 코드는, try 또는 except 코드를 실행한 후 항상 실행된다.

try:
  print("Hello")
  print(1 / 0)
except ZeroDivisionError:
  print("Divided by zero")
finally:
  print("This code will run no matter what")
  
# Hello
# Divided by zero
# This code will run no matter what

• Code in a finally statement even runs if an uncaught exception occurs in one of the preceding blocks.
  • finally 문의 코드는, 앞의 블록 중 하나에서 예외가 발생한 경우에도 실행된다.

try:
  print(1)
  print(10 / 0)
except ZeroDivisionError:
  print(unknown_var)
finally:
  print("This is executed last")
  
# 1
# This is executed last

# ZeroDivisionError: division by zero
# During handling of the above exception, another exception occurred:
# NameError: name 'unknown_var' is not defined
