python怎么安装matplotlib-为python安装matplotlib模块

matplotlib是python中强大的画图模块。

首先确保已经安装python，然后用pip来安装matplotlib模块。

进入到cmd窗口下，执行python -m pip install -U pip setuptools进行升级。

接着键入python -m pip install matplotlib进行自动的安装，系统会自动下载安装包。

安装完成后，可以用python -m pip list查看本机的安装的所有模块，确保matplotlib已经安装成功。

进入到python idle中，运行import matplotlib，如下图所示，如果没有报错提示，那就可以开始使用了。
