# # 基本捕获异常语法
# try:
#     f = open("D:/program/abc.txt", 'r', encoding='UTF-8')
# except:
#     print("出现异常，文件不存在")
#
# # 捕获指定异常
# try:
#     print(name)
# except NameError as a:
#     print("出现变量未定义的异常")
#
# # 捕获多个异常
# try:
#     1 / 0
# except(NameError, ZeroDivisionError) as b:
#     print("出现变量未定义，或者除以0的异常错误")
#
# # 捕获所有异常
# try:
#     1 / 0
# except Exception as c:
#     print("出现异常")
# else:
#     print("无异常")

# 异常传递
