Here’s a simple Python script to automate a system check:

import psutil

def check_cpu_usage():
    usage = psutil.cpu_percent(interval=1)
    return f"CPU Usage: {usage}%"

def check_memory_usage():
    memory = psutil.virtual_memory()
    return f"Memory Usage: {memory.percent}%"

print(check_cpu_usage())
print(check_memory_usage())
