Exercise 18 Threading demonstration in Python
I created the file threaddemo.py file by copy and paste from the study guide. The codes are paste into the shell of python and run the module. At first I got some errors relating to the indent of my codes. After indenting the codes into the right indent position, there were no more errors and the module was run successfully with the following output:-

The format of the output is similar to the output given in the study guide. However the values of the processing times are different due to the difference in processing speed of my desktop computer which is expected.
