Python获取Linux系统内存情况，pythonlinux,[Python]代码

[Python]代码 ``` pythonimport subprocessimport 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"))```
