Python İle Sistem Bilgilerinin Sorgulanması

Yaptığınız uygulamada CPU, Memory, Network ve Disk bilgilerini kullanıcılara göstermek isteyebilirsiniz veya sistemin genel durumunu kontrol etmek için geliştirmeler yapabilirsiniz. psutil aracılığı ile bu ve buna benzer bilgileri topladığımız kodumuz şu şekildedir.

    for s in reversed(symbols):

            value = float(n) / prefix[s]
            return '%.1f%s' % (value, s)
