老师，config中设置了json数据编码问题，但是返回的json数据还是不显示中文

老师 安装的软件 打开控制台不太一样 怎么会这样尼

什么是”常量字符串“？是不是相对应的，有”非常量字符串“？

课上老师说：用双引号引起来的字符串就是常量字符串。可是字符串不都是用双引号引起来的吗？

这个都已有一个月了，老师们，走点心，这个都已有一个月了，老师们，走点心，

from urllib.request import Request, build_opener
from fake_useragent import UserAgent
from urllib.request import HTTPHandler

url = 'http://httpbin.org/get'
ua = UserAgent()
# print(ua.random)
headers = {
    'User-Agent': ua.chrome
}
request = Request(url, headers=headers)
# HTTP控制器
handler = HTTPHandler()
opener = build_opener(handler)
response = opener.open(url)
print(response.read().decode())

为什么这个请求头中User—Agent 是没有伪装过的？

    老师如果用进程池生成进程的话，进程间通信可否操作？进程间通信指的是子进程之间的通信，如果父进程与子进程通信？

else旁边的那个可收缩节点怎么设置

老师，这里的KPI图显示的默认是12月的情况啊，也不是12个月的求和或者平均的比较啊，那这样的话前11个月的数据在KPI图中不就没有意义了么？

老师，第91课都没讲完，你看看能不能更新一下，上传个完整的。

老师，请问这是什么问题，，我没有头绪

为什么连接不了？？？

1、这是全局变量resule = []
import time
start = time.time()
result = []
for i in range(1000):
    for m in range(10000):
        result.append(i*1000+m*100)
end = time.time()
print('耗时：{0}'.format((end-start)))


2、这是局部变量result = []
import time
start = time.time()
for i in range(1000):
    result = []
    for m in range(10000):
        result.append(i*1000+m*100)
end = time.time()
print('耗时：{0}'.format((end-start)))


3、老师能从底层原理解释下为什么局部变量查询较快？

老师这一直插不进去数据

写一个函数，计算下面的数列

这个不会  老师帮忙讲解一下，谢谢

我后面也试过那个方法；百度上也和你说的一样，不过我试了，还是报错。不管用什么方法拼都是差不多的错误。
最后我用管理员身份打开拼，它就可以了；不知道为什么，在前面几个阶段学校中我都是这样直接拼，
直接下载都可以，可是现在就不行了
