Hello, Internet programmers let’s do a code in python to show laptop battery percentage. Let’s jump to the code.
We are gonna use psutil python module to do this task. psutil (process and system utilities) is a cross-platform library for retrieving information on running processes and system utilization (CPU, memory, disks, network, sensors) in Python.
It is useful mainly for system monitoring, profiling and limiting process resources and management of running processes. It implements many functionalities offered by classic UNIX command line tools such as ps, top, iotop, lsof, netstat, ifconfig, free and others. psutil currently supports the following platforms:
- FreeBSD, OpenBSD, NetBSD
- Sun Solaris
Open your terminal and type the following command and it starts downloading
pip install psutil
Install psutil in Linux
sudo apt-get install gcc python3-dev sudo pip3 install psutil
# python script showing battery details import psutil # function returning time in hh:mm:ss def convertTime(seconds): minutes, seconds = divmod(seconds, 60) hours, minutes = divmod(minutes, 60) return "%d:%02d:%02d" % (hours, minutes, seconds) # returns a tuple battery = psutil.sensors_battery() print("Battery percentage : ", battery.percent) print("Power plugged in : ", battery.power_plugged) # converting seconds to hh:mm:ss print("Battery left : ", convertTime(battery.secsleft))
psutil.sensors.battery() returns a named tuple consisting of the following values. If no battery is installed or metrics can’t be determined None is returned.
percent: Power left in percentage.
secsleft: Approx seconds left before the power runs out. It is set to
psutil.POWER_TIME_UNLIMITEDif it is on charging. If this value can’t be determined it is set to
power_plugged: True if power is plugged in, False if it isn’t charging or None if it can’t be determined.
Happy Coding 🙂
