Open Chromium on your Raspi and go to the github for this assignment and download the file to your assignment folder, or create a new python file with the code below, and test it
In this script we are creating a user defined function called get_ip_address() by using the "def" command.import socket
import socket
import fcntl
import struct
def get_ip_address(ifname):
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
# uncomment the following line if using python2
#return socket.inet_ntoa(fcntl.ioctl(s.fileno(),0x8915,struct.pack('256s',ifname[:15]))[20:24])
# uncomment the following line if using python3
return socket.inet_ntoa(fcntl.ioctl(s.fileno(),0x8915,struct.pack('256s',bytes(ifname[:15],'utf-8')))[20:24])
address = get_ip_address('wlan0')
#change wlan0 to eth0 if you want the wired IP address
print(address)
Note, we are passing wlan0 as the argument. If you are using ethernet you would pass eth0 as the argument

In Thonny go to Tools/Manage Packages and search for fcntl, and install it
