【问题描述】：
我对我正在做的一项 python 作业有疑问，想向社区寻求一些指导。我将仅将 socket 模块 和 argparse 模块用于此任务。我创建了一个 socketserver.py 文件和一个 socketclient.py 文件。服务器和客户端之间的连接很好。现在分配的目的是客户端使用 argparse 发送彩票游戏类型、票数和每票的行数。例如。 socketclient.py 的语法是 python3 -t Lotto_Max -n 2 -l 2。票务游戏的输出、票务类型和每张票的行数正确显示在服务器上。但是，它们有时无法在客户端上正确显示，并且目前确实卡住了。这是我的以下代码....
服务器代码
```socketserver.py code```
import socket
from random import sample
def main():
host = input("Please specify an IP address for this server's socket\t")
port = int(input('Please speciy a port number above 1024 for this socket.\t'))
kulmiye = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try:
kulmiye.bind((host, port))
except socket.error as egeh:
print('Socket bind failed. Error Code : ' + str(egeh[0]) + ' Message ' + egeh[1])
print('Socket bind accomplished...\n')
print("Listening for an incoming connection...")
kulmiye.listen()
conn, addr = kulmiye.accept()
print('Connected with ' + addr[0] + ':' + str(addr[1]))
while True:
server_data = conn.recv(1024).decode("utf-8")
game_data = server_data.split(",")
if not server_data:
break
if game_data[0] == "Lotto_Max":
nval = int(game_data[1])
lval = int(game_data[2])
for nval in range(nval):
for i in range(lval):
numbers = sample(range(1, 50), 7)
numbers.sort()
sortedd = str(numbers)
print(sortedd)
print("--------------------")
conn.sendall(sortedd.encode("utf-8"))
#conn.sendall(bytes(str(numbers),'utf-8'))
liners = "-----------------------"
conn.sendall(liners.encode("utf-8"))
print("From Client: " + str(game_data))
conn.sendall(b'goodbye')
# server_data = input('#\t')
break
else:
conn.close()
if __name__ == '__main__':
main()
客户代码
```socketclient.py code```
import socket
import argparse
def client():
host = input("Please specify the server's IP you want to connect to\t")
port = int(input("Please specify the server's port you want to connect to\t"))
kulmiye = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
kulmiye.connect((host, port))
# client_data = input("#\t")
# while True:
# client_data = input()
# if client_data == 'quit':
# kulmiye.close()
# sys.exit()
# if len(str.encode(client_data)) > 0:
# kulmiye.sendall(str.encode(client_data))
# server_response = str(kulmiye.recv(1024), "utf-8")
# print(server_response, end = " ")
kulmiye.sendall(bytes(tvar.encode("utf-8")))
kulmiye.sendall(bytes(','.encode("utf-8")))
kulmiye.sendall(bytes(str(nval).encode("utf-8")))
kulmiye.sendall(bytes(','.encode("utf-8")))
kulmiye.sendall(bytes(str(lval).encode("utf-8")))
server_data = kulmiye.recv(1024).decode("utf-8")
while server_data != 'goodbye':
server_data = kulmiye.recv(1024).decode("utf-8")
print('Server: \n' + server_data)
# client_data = input("#\t")
if not server_data:
break
kulmiye.close()
# this code block serves to give the user the ability to play lotto max
# with the amount of tickets and lines per ticket they would like
# Using the argparse module to allow the user to input command-line interfaces
parser = argparse.ArgumentParser(description='Welcome to OLG Gaming.')
parser.add_argument(
'-t',
type=str,
help="Pick the lottery you want to play",
required=True)
parser.add_argument(
'-n',
type=int,
help="Pick the amount of lottery tickets you want to play",
required=True)
parser.add_argument(
'-l',
type=int,
help="Pick the amount of lines you would like to play",
required=True)
# parser.add_argument('-o', type = str, help = "This is optional", required = False)
# parse_args will convert the argument strings into objects and will get
# stored in the cmdargs variable
cmdargs = parser.parse_args()
tvar = cmdargs.t # the t string argument that gets parsed into an object will get stored into a variable called tvar
# the n integer argument that gets parsed into an object will get stored
# into a variable called nval
nval = int(cmdargs.n)
# the l integer argument that gets parsed into an object will get stored
# into a variable called lval
lval = int(cmdargs.l)
if __name__ == "__main__":
client()
```code```
服务器
python3 socketserver.py
- 将 localhost 指定为 IP
- 指定一个端口，例如第4444章
客户
python3 socketclient.py -t Lotto_Max -n 1 -l 1
- 指定一个 IP 地址连接到服务器（例如 localhost 或 127.0.0.1）
- 指定要连接的端口，例如第4444章
当客户端和服务器之间建立连接时，服务器接收客户端输入并在其末端打印游戏类型（Lotto_Max）、票数和每票行
服务器将输出结果例如
但是，客户不会无限期地收到它。通常它会得到大约 25% 的时间，我不知道为什么

请将您的代码减少到演示问题所需的最低限度。包含输入以及期望和观察到的输出也将有所帮助。
