Python timer usage + get script where absolute path + define log format test code

If you write a script with a timer in Python, if the script also read the configuration file, then the configuration file path if you write to die, one day to change the directory, you need to change the script configuration file path, and every time the script is located in the path with nohup boot to the background is very troublesome.
Using Os.path.split (Os.path.realpath (sys.argv[0])) [0] to get the absolute path of the file, the configuration file is also thrown to its peers, so that it can be started anywhere, once and for all ~ ~ ~

This usage station is commonly used in the operation of the thinking, put to any path can be called under any path, solve the problem of the path is not correct.

Python script
