TCP, UDP For example: Import socketS=socket.socket (Socket.af_inet,socket. SOCK_STREAM)Port=socket.getservbyname (' http ', ' TCP ')Port has a return value of 80. If read:Port=socket.getservbyname (' SMTP ', ' TCP ')Port has a return value of 25. 4, from the socket to obtain information After you establish a socket connection, you can obtain its own IP address and port number by getsockname (), or you can display the IP address and port number of the remote machine by Getpeername ().For exa

redirect the libraries that the output project uses. Pip Freeze > Requirements.txt This will redirect the third-party library in the environment to the requirements.txt file, and if you give others a dependency on the project, you only need to run: Pip Install-r requirements.txt It's very convenient. Of course, sometimes, our network is not so smooth, pip is installed online, can you leave floss? Of course
