Python获取Linux系统内存情况
[Python]代码 “` python
import subprocess
import re
keydic = {“MemTotal”:”总内存(单位G)”,
“MemFree”:”剩余内存(单位G)”,
“MemAvailable”:”可用内存(单位G)”,
“Cached”:”缓存内存(单位G)”}
def command(command):
p = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
resultDic = {}
for line in p.stdout.readlines():
line = str(line,encoding=”utf-8″)
result = re.split(“\s“,line)
if result[0][:-1] in keydic:
resultDic[keydic[result[0][:-1]]] = “%.2f” %(int(result[1])/(1024*2))
return resultDic
if name == “main”:
print(command(“cat /proc/meminfo”))
