Looking for Confirmation on My Python Script for Getting Computer Specs

Hey everyone! I'm trying to gather my computer specifications using a script without relying on any third-party software. I asked ChatGPT for help, but since I have zero coding knowledge, I want to ensure that the code it provided works properly.

Here's the code snippet I have:

```python
import platform
import psutil
import shutil
import subprocess
import os
import sys

def get_cpu_info():
cpu = platform.processor() or "Unknown"
freq = psutil.cpu_freq()
speed = f"{freq.max:.2f} MHz" if freq else "Unknown"
return cpu, speed

def get_ram():
ram = psutil.virtual_memory().total /(1024 ** 3)
return f"{ram:.2f} GB"

def get_gpu_info():
try:
if sys.platform == "win32":
cmd = "wmic path win32_VideoController get name,AdapterRAM"
output = subprocess.check_output(cmd, shell=True).decode()
lines = output.strip().split("n")[1:]
if lines:
name = lines[0].split()[0]
ram = int(lines[0].split()[-1]) /(1024 ** 2)
return name, f"{ram:.2f} MB"
elif sys.platform == "darwin":
output = subprocess.check_output(["system_profiler", "SPDisplaysDataType"]).decode()
lines = [line.strip() for line in output.split("n") if "Chipset Model" in line or "VRAM" in line]
name = lines[0].split(":")[-1].strip()
vram = lines[1].split(":")[-1].strip()
return name, vram
else: # Linux
output = subprocess.check_output("lspci | grep VGA", shell=True).decode()
name = output.strip().split(":")[-1].strip()
return name, "Unknown"
except Exception as e:
return "Unknown", "Unknown"

def get_os():
return f"{platform.system()} {platform.release()}"

def get_free_disk():
free = shutil.disk_usage("/").free /(1024 ** 3)
return f"{free:.2f} GB"

def get_shader_model():
if sys.platform == "win32":
try:
output = subprocess.check_output("dxdiag /t dxdiag_output.txt", shell=True)
with open("dxdiag_output.txt", "r", encoding="utf-8", errors="ignore") as file:
content = file.read()
os.remove("dxdiag_output.txt")
pixel = "Unknown"
vertex = "Unknown"
for line in content.splitlines():
if "Pixel Shader" in line:
pixel = line.split(":")[-1].strip()
if "Vertex Shader" in line:
vertex = line.split(":")[-1].strip()
return pixel, vertex
except:
return "Unknown", "Unknown"
else:
return "N/A", "N/A"

if __name__ == "__main__":
cpu, cpu_speed = get_cpu_info()
ram = get_ram()
gpu, vram = get_gpu_info()
os_info = get_os()
disk = get_free_disk()
pixel_shader, vertex_shader = get_shader_model()

print(f"CPU: {cpu}")
print(f"CPU SPEED: {cpu_speed}")
print(f"RAM: {ram}")
print(f"VIDEO CARD: {gpu}")
print(f"DEDICATED VIDEO RAM: {vram}")
print(f"PIXEL SHADER: {pixel_shader}")
print(f"VERTEX SHADER: {vertex_shader}")
print(f"OS: {os_info}")
print(f"FREE DISK SPACE: {disk}")
```

I would appreciate it if someone could review this code and confirm that there's nothing excessive or incorrect. Also, if there's a way to improve it, I'm all for it!
