Python prints a list of the programs that occupy memory Top10 in tabular form

This topic is related to Python's operation of the process, the number of cycles for a loop count, sorting and printing the table, and so on, as follows:

650) this.width=650; "title=" image "style=" border-top:0px;border-right:0px;border-bottom:0px;border-left:0px; " Border= "0" alt= "image" Src= "Http://s3.51cto.com/wyfs02/M01/87/E0/wKiom1fjlJHQo9qxAABFEPuFGyw567.png" height= "414" />

The code is as follows:

The code can also be obtained from GitHub, https://github.com/DingGuodong/LinuxBashShellScriptForOps/blob/master/functions/process/performanceOps.py

It uses two major third-party modules, Psutil (for getting process information) and prettytable (for printing tables), available on both Windows and Linux systems, if prompted with "Importerror:no module named xxxx", You can execute the command pip install xxxx or easy_install xxxx.
