Parsing data in a file containing systeminfo information

Question

A "txt" file containing command return information was generated systeminfo, and I need to be able to copy some of the lines of the file, in this case, the ones that contain information about: total physical memory, available physical memory, virtual memory, maximum size, available and in use:

Total Physical Memory: 16.282 MB
Available Physical Memory: 10.111 MB
Virtual Memory: Max Size: 18.714 MB
Virtual Memory: Available: 10.798 MB
Virtual Memory: In Use: 7.916 MB

To get the executed file at the prompt: systeminfo > saida_systeminfo.txt

Follow code under development:

archive_sysinfo = open('saida_systeminfo.txt', 'r')
text_sysinfo = archive_sysinfo.readlines()
lista_linhas2 = []
lista_info = []

for linha2 in text_sysinfo:
    lista_linhas2.append(linha2.split())
    print(linha2.split())

for linha2 in lista_linhas2:
    if "Mem¢ria" in linha2:
    lista_info.append(linha2[0:5])

lista_info = open("resultado_info.txt","w")
lista_info.write("Coletando dados de memoria")

string_info = ""
for j in range(0,7,1):
    string_info = lista_info[j][0] + " " + lista_info[j][1] + " " + 
lista_info[j][2] + " " + lista_info[j][3] + " " + lista_info[j][4] + "\n"
    print(string_info)
    lista_info.write(string_info)
