finally 块执行代码
使用 finally 块执行代码，不论 try 块是否引发了错误
以下实例为学习使用 finally 块执行代码，不论 try 块是否引发了错误，具体代码如下：
# Filename : example.py
# Author by : www.lidihuo.com
#The finally block gets executed no matter if the try block raises any errors or not:
try:
print(x)
except:
print("Something went wrong")
finally:
print("The 'try except' is finished")
执行以上代码输出结果为：
# Filename : example.py
# Author by : www.lidihuo.com
Something went wrong
The 'try except' is finished
