Memory Information

Read the memory information from the system file /proc/meminfo.

Example:

def get_mem_info():
        mem_info = ""
        f_mem_info = open("/proc/meminfo")
        try:
                for line in f_mem_info:
                        if (line.find("MemTotal") == 0):
                                mem_info += line.strip()+ ", "
                        elif (line.find("SwapTotal") == 0):
                                mem_info += line.strip()
                                break
                print("mem_info---- {:s}".format(mem_info))
        finally:
                f_mem_info.close()
