很抱歉,如果这有点模糊,或者已经被问过,但我不确定术语,所以我不能谷歌。我正在寻找的是如何将psutil.virtual_memory()赋予不同变量的参数分配 例如,调用psutil.virtual_memory()会提供(total=8374149120L, available=1247768576L, percent=85.1, used=8246628352L, free=127520768L, active=3208777728, inactive=1133408256, buffers=342413312L, cached=777834496)

我只想获取percent值,并将其分配给变量。我怎么能这样呢?

返回namedtuple(称为vrem),因此请使用percent = psutil.virtual_memory().percent
