Python

简介Python捕获异常的相关操作，try/except。

try:
    # 主代码块
    pass
except KeyError as e:
    # 异常时，执行该块
    pass
else:
    # 主代码块执行完，执行该块
    pass
finally:
    # 无论异常与否，最终执行该块
    pass

try:
    int("error")
except Exception as e:
    print(e)

try:
    int("error")
except IndexError as e:
    print(e)
except KeyError as e:
    print(e)
except ValueError as e:
    print(e)

try:
    int("error"
except KeyError as e:
    print(e)
except Exception as e:
    print(e)
