idx_b = data[:,1] == 0 and data[:,4] == 1用and会提示错误， 因为and 最终只给定一个bool值， 要么用.all() 或 .any()所以这里用& 是正确， 会给定一个bool值的array, 它是elementwise的https://stackoverflow.com/questions/10062954/valueerror-th...

在APP上申请了一个黄巴帐号，由于email输错了，导致买了七天的票不能使用，想找回， 公司却说只能找回密码，不能找回帐号，黄巴的网站也像一坨屎，居然email不经过验证直接可以用，导致你输错了都不知道，于是不甘心白白亏掉自己的12镑于是决定，暴力破解之。先用Python生成帐号字典：import osfrom string import ascii_lowercase

线程和进程计算机，用于计算的机器。计算机的核心是CPU，在现在多核心的电脑很常见了。为了充分利用cpu核心做计算任务，程序实现了多线程模型。通过多线程实现多任务的并行执行。现在的操作系统多是多任务操作系统。每个应用程序都有一个自己的进程。操作系统会为这些进程分配一些执行资源，例如内存空间等。在进程中，又可以创建一些线程，他们共享这些内存空间，并由操作系统调用，以便并行计算。

Requests 是用Python语言编写，基于 urllib，采用 Apache2 Licensed 开源协议的 HTTP 库。它比 urllib 更加方便，可以节约我们大量的工作，完全满足 HTTP 测试需求。Requests 的哲学是以 PEP 20 的习语为中心开发的，所以它比 urllib 更加 Pythoner。更重要的一点是它支持 Python3 哦！Beautifu
