Python2 得到 CPU 和内存信息要怎么实现呢？

ls ('cat >/proc/cpuinfo')
ls ('cat >/proc/meminfo')

。。。。这个 Google 一下不就有了么。。
psutil

谢谢。附上写好的代码。

```python
#!/usr/bin/env python
import time
import psutil

line_num = 1

def print_line (str ):
print str

#function of Get CPU State
def getCPUstate (interval=1 ):
return (" CPU: " + str (psutil.cpu_percent (interval )) + "%")

#function of Get Memory
def getMemorystate ():
phymem = psutil.phymem_usage ()
buffers = getattr (psutil, 'phymem_buffers', lambda: 0 )()
cached = getattr (psutil, 'cached_phymem', lambda: 0 )()
used = phymem.total - (phymem.free + buffers + cached )
line = " Memory: %6s" % (
str (int (used / 1024 / 1024 )) + "M",
)
return line

def poll (interval ):
"""Retrieve raw stats within an interval window."""
# sleep some time
time.sleep (interval )
# get cpu state
cpu_state = getCPUstate (interval )
# get memory
memory_state = getMemorystate ()
return (cpu_state,memory_state )

def refresh_window (cpu_state,memory_state ):
#print current time #cpu state #memory
print_line (time.asctime ())
print_line (cpu_state )
print_line (memory_state )

try:
interval =0
while 1:
args = poll (interval )
refresh_window (*args )
interval = 1
except (KeyboardInterrupt, SystemExit ):
pass
```
