Use the python-psutil package to query disk information, such as: total space, used space, free space, etc.

Before using it, you need to import psutil. The following is a test program that reads the total space, used space, and free space of the disk and memory, and displays them in GB:

  1 # -*- coding:utf-8 -*-
  2 import psutil
  3 
  4 def main():
  5   print '>> disk total   >> ' + str(psutil.disk_usage("/").total)
  6   print '>> disk used    >> ' + str(psutil.disk_usage("/").used)
  7   print '>> disk avail   >> ' + str(psutil.disk_usage("/").free)
  8   print '>> disk percent >> ' + str(psutil.disk_usage("/").percent) + ' %' + '\n'
  9 
 10   print '>> disk total/G >> ' + \
 11     str(round((((float(psutil.disk_usage("/").total)/1024)/1024)/1024), 2)) + 'G'
 12   print '>> disk used /G >> ' + \
 13     str(round((((float(psutil.disk_usage("/").used) /1024)/1024)/1024), 2)) + 'G'
 14   print '>> disk avail/G >> ' + \
 15     str(round((((float(psutil.disk_usage("/").free) /1024)/1024)/1024), 2)) + 'G' + '\n'
 16 
 17   virtual_mem = psutil.virtual_memory()
 18   print '>> mem total    >> ' + str(virtual_mem.total)
 19   print '>> mem used     >> ' + str(virtual_mem.total - virtual_mem.available)
 20   print '>> mem avail    >> ' + str(virtual_mem.available) + '\n'
 21 
 22   print '>> mem total /G >> ' + \
 23     str(round((((float(virtual_mem.total)/1024)/1024)/1024), 2)) + 'G'
 24   print '>> mem used  /G >> ' + \
 25     str(round((((float(virtual_mem.total-virtual_mem.available)/1024)/1024)/1024),2))+'G'
 26   print '>> mem avail /G >> ' + \
 27     str(round((((float(virtual_mem.available)/1024)/1024)/1024), 2)) + 'G' + '\n'
