This is a simple implementation of client-server file transfer via Socket API
To launch the program first run server.py with
$ python3 server.py
Then run client.py with arguments filename, ip and port. Example:
$ python3 client.py file.txt 13.37.13.37 1337
As a result, the file in the directory of client.py file will be transfered to the directory of server with address ip:port
Update: filenames are also resolved. E.g. if file 1.jpg already exists on server storage, it will obtain name 1_copy1.jpg
