How to find local IP address by Python
I found two implementations.
One
import socket
socket.gethostbyname(socket.gethostname())
Two: recommend!
This way will create a new UDP package and adding local IP address in it.
It will not actually send the package。
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.connect(("8.8.8.8", 80))
print(s.getsockname()[0])
s.close()
