Sometimes the need for python program to monitor memory usage, this time can be used psutil library, Anaconda is built-in, if import error, you can use pip install psutil (installed in python) or conda install psutil (installed in Anaconda in)
#常用的：
import psutil
import os
info = psutil.virtual_memory()
print u'内存使用：',psutil.Process(os.getpid()).memory_info().rss
print u'总内存：',info.total
print u'内存占比：',info.percent
print u'cpu个数：',psutil.cpu_count()
Other built-in methods or properties are:
boot_time
callable
collections
cpu_count
cpu_percent
cpu_stats
cpu_times
cpu_times_percent
disk_io_counters
disk_partitions
disk_usage
errno
functools
long
net_connections
net_if_addrs
net_if_stats
net_io_counters
os
pid_exists
pids
process_iter
pwd
signal
subprocess
swap_memory
sys
test
time
traceback
users
version_info
virtual_memory
wait_procs
win_service_get
win_service_iter
View windows boot time
import time
import psutil
print (u'电脑开机时间：{}'.format(time.strftime('%y-%m-%d %H:%M:%S', time.localtime(psutil.boot_time()))))
