套接字服务器端函数返回“'；dict'；对象不可调用"；python

我在客户端和服务器之间有一个套接字。 服务器可以访问有关约会的数据库，并检查约会的状态是否未知，然后将其发送给客户端，客户端可以访问本地API

服务器端：

context = ssl.SSLContext(ssl.PROTOCOL_TLS_SERVER)
context.load_cert_chain('','')
sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM,0)
sock.bind(('0.0.0.0',8443))
sock.listen(5)
print('Server Listening')
ssock = context.wrap_socket(sock,server_side=True)
conn,address = ssock.accept()
datatype = "appointment"

def status_check(code,purpose)
    codeDic = {'1001':'CX', .... }
    stat = codeDic(code)
    if stat = 'Yes':
        if purpose.find('repair')!=-1:
            stat = 'RP'
    return stat

if datatype == "appointment":
                x = 'NYIs'
                xst = x.encode()
                conn.send(xst)
                for appt in data:
                    st = repr(appt)
                    encoded = st.encode()
                    conn.send(encoded)
                    rec = conn.recv(2048)
                    rec = rec.decode("UTF-8")
                    rec = eval(rec)
                    if rec!='none':
                        print(rec.keys()) 
                        print(rec.values())
                        statuscode1 = str(rec.get("status"))
                        purpose1 = str(rec.get("purposeofvisit"))
                        status1 = status_check(statuscode1,purpose1) \\\This line cause the error
                x= 'done'
                xst = x.encode()
                conn.send(xst)
                appointments.append(data)

客户：

if x=='NYIs':
   while x!='done':
       appt = ssock.recv(1024)
       appt = appt.decode("UTF-8")
       try:
           appt=eval(appt)
           PARAMS = {'limit':'10','date':appt[2].strftime('%m-%d-%Y'),'firstname':appt[1],'lastname':appt[2]}
           r = requests.get(url=URL, params=PARAMS, timeout =10)
           if r:
               data = repr(r.json()[0])
           else:
               data = repr('none')
           encoded = data.encode()
           ssock.send(encoded)
       except NameError:
           appt=appt
       x=appt

stat=codeDic（code）

应该是

stat=codeDic[code]

stat=codeDic（code）

应该是

stat=codeDic[code]
