Why does this not connect me to my server?

Question

I am trying to establish a connection to server.py but client.py outputs this error

Traceback (most recent call last):
  File "C:\Users\Nathan\Desktop\Coding\Langs\Python\Projects\Chatting Program\Client.py", line 15, in <module>
    clientsocket.connect((host, port)) # Connects to the server
TypeError: an integer is required (got type str)

Here is my code...

## CLIENT.PY
from socket import *
import socket

host = input("Host: ")
port = input("Port: ")
#int(port)

username = input("Username: ")
username = "<" + username + ">"
print(f"Connecting under nick \"{username}\"")

clientsocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # Creates socket
clientsocket.connect((host, port)) # Connects to the server

while True:
    Csend = input("<MSG> ") # Input message
    Csend = f"{username} {Csend}" # Add username to message
    clientsocket.send(Csend) # Send message to ONLY the server

If there is an issue with my server.py then here is the code to that

## SERVER.PY
from socket import *
import socket
import select

host_name = socket.gethostname()

HOST = socket.gethostbyname(host_name) 
PORT = 12345

print(f"Server Info\nHOST: {HOST}\nPORT: {PORT}")

serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
serversocket.bind((HOST, PORT))
serversocket.listen(5)
clientsocket, address = serversocket.accept()

print(address)
with clientsocket:
    while True:
        Srecv = clientsocket.recv(1024)
        print(f"{username} - {address}: {Srecv}")
        # Add server time to message before sending
        clientsocket.sendall(Srecv)

I have tried converting host and port into str, int, and float, but it only successfully converts into str. Any help would be greatly appreciated. Thanks in advance!

Converting the port number to an integer would have been the right approach. What was the problem with it? — mkrieger1, Mar 24 '20 at 22:38

The compile error is pretty fair: input() returns a string for the port number, whereas your function needs an integer. You can fix that by casting the port to an integer - your comment is close:

port = int(port).

If you look at the python documentation, input() always returns a string. The second value in the tuple passed to clientsocket.connect() must be a integer, however, you are passing a your string value. You must cast your port first, with the following code:

port = int(port).

#OR

port = int(input("Port: "))

Always check the docs!
