Python script to shows Laptop Battery Percentage
psutil is a cross-platform library for retrieving information on running processes and system utilization(CPU, memory, disks, networks, sensors) in Python. The Python script below can be run in both Windows and Linux. Install psutil in windows by :

pip install psutil
Install psutil in Linux by:

sudo apt-get install gcc python3-dev
sudo pip3 install psutil
Code:

# 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))
Output:

Battery percentage : 57
Power plugged in : False
Battery left : 1:58:32
Explanation:

psutil.sensors.battery() returns a named tuple consisting of 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_UNLIMITED if it is on charging. If this value can’t be determined it is set to psutil.POWER_TIME_UNKNOWN .
power_plugged: True if power is plugged in, False if it isn’t charging or None if it can’t be determined.
