on channel: Tempcoder Tech

🔄 Welcome back to TempCoder Tech! In this quick follow-up to our recent CPU times exploration, we're diving into the fascinating realm of Python with psutil.cpu_times(percpu=False). Join us as we switch from True to False, comparing the results and understanding the impact. If you missed our first video, catch up for a deeper dive into CPU times with psutil.cpu_times(percpu=True).

🚀 What's Covered:

Switching from psutil.cpu_times(percpu=True) to psutil.cpu_times(percpu=False).
Understanding the difference in results.
Logging combined CPU times for analysis.
Quick comparison with our previous percpu=True results.

👩‍💻 Code Snippet:

import psutil
import time

def log_cpu_times(percpu_option):
Get CPU times using psutil.cpu_times(percpu=percpu_option)
cpu_times = psutil.cpu_times(percpu=percpu_option)

Get current timestamp
timestamp = time.strftime('%Y-%m-%d %H:%M:%S')

Create or open a log file
with open('cpu_times_log.txt', 'a') as file:
Write timestamp and CPU times to the file
file.write(f'\nTimestamp: {timestamp}\n')
if percpu_option:
for i, cpu in enumerate(cpu_times):
file.write(f'CPU {i + 1}: {cpu}\n')
else:
file.write(f'Combined CPU Times: {cpu_times}\n')

print(f'CPU times logged at {timestamp}')

Onscreen text: "Switching to psutil.cpu_times(percpu=False)"
Run the function immediately with percpu=False
log_cpu_times(percpu_option=False)

Onscreen text: "Comparing combined CPU times with previous percpu=True"
Log every 5 seconds for 3 times
for _ in range(3):
time.sleep(5)
log_cpu_times(percpu_option=False)

💡 Why Watch?

Uncover the impact of percpu=False in CPU times.
Quick comparison with our previous percpu=True exploration.
Deepen your understanding of Python's psutil library.
