python - take in user input while also outputting strings

Question

In most console and IRC applications, the user can make inputs while the console is also making outputs. Is this possible in python? and if so, how? I am trying to make an IRC-like application and I have tried using multiple threads at once, but the input is never fully registered. I have made the server repeat a message every couple of seconds for testing purposes.

Here is the code for the client:

import socket
import threading

TARGET_IP = socket.gethostname()

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) #create socket object using IPV4 and TCP respectively

def utf8len(a):
    return len(a.encode('utf-8')) #returns length of string in unicode

def recievethread():
    while True:
        full_msg = ''
        msg = s.recv(1024) #waits to recieve message
        full_msg += msg.decode("utf-8") #decode
        print(full_msg) #print
        
def inputthread():
    while True: #input loop
        inp = input()
        print("[DEBUG] - {inp}")
        if inp == "!04exit":
            recieving.exit()
            print("[CLIENT] - Closing connection to {TARGET_IP}!")
            break #safely close the client with all threads
        
        if utf8len(inp) < 1024:
            pass
        else:
            print("[CLIENT] - message is too long!")

s.connect((TARGET_IP, 1432)) #establish connection on the same machine for now

recieving = threading.Thread(target=recievethread)
recieving.start()
inputloop = threading.Thread(target=inputthread)
inputloop.start()

And this is what happens when I try to make an input while the server is running:

$ python client.py
