具体的解决方法如下：

1.  在request后面写入一个关闭的操作，

response.close()

2.  设置socket默认的等待时间，在read超时后能自动往下继续跑

socket.setdefaulttimeout(t_default)

3.  设置sleep()等待一段时间后继续下面的操作

time.sleep(t)

#coding=utf-8
import urllib.request
import urllib.error
from bs4 import BeautifulSoup
import time
import socket
 
socket.setdefaulttimeout(20)  # 设置socket层的超时时间为20秒
header = {'User-Agent': 'Mozilla/5.0'}
url = []
print('输入需要查询的基金号，按Q结束\n')
while True:
	n = input()
	if n == 'Q':
		break
	elif n:
		t = 'http://fund.eastmoney.com/{0}.html?spm-search'.format(n)
		url.append(t)
	else:
		print('输入错误')
 
for i in url:
	request = urllib.request.Request(i, headers=header)
	try:
		response = urllib.request.urlopen(request)
		soup = BeautifulSoup(response, 'html.parser')		
		title = soup.find('div', attrs={'class': 'fundDetail-tit'})
		rate = soup.find('span', attrs={'id': 'gz_gszzl'})
		print(title.text, rate.text)
		response.close()	# 注意关闭response
	except urllib.error.URLError as e:
		print(e.reason)
	time.sleep(1)	# 自定义
