学习Python ，win10 安装tqdm

Tqdm 是一个快速，可扩展的Python进度条，可以在 Python 长循环中添加一个进度提示信息，用户只需要封装任意的迭代器 tqdm(iterator)。

我的系统是window环境，首先安装python，接下来就是pip。安装方法参考https://mp.csdn.net/postedit/84558019

 

 

win10以管理员身份运行cmd，一定要管理员 不然会出现 WinError 5的报错。

进入安装好的Python目录

然后在CMD窗口进入python下面：

输出：

python -m pip install -U pip

C:\Program Files\Python37>pip install tqdm
