这篇文章主要介绍了python如何读取。垫文件并取出信息,具有一定借鉴价值,感兴趣的朋友可以参考下,希望大家阅读完这篇文章之后大有收获、下面让小编带着大家一起了解一下。
python是一种跨平台的,具有解释性,编译性,互动性和面向对象的脚本语言,其最初的设计是用于编写自动化脚本,随着版本的不断更新和新功能的添加,常用于用于开发独立的项目和大型项目。
<>强导入所需包
<强>读取。垫文件
随便从下面文件里读取一个:
读出来的米内容:
<>强取出.mat里所需信息
。垫文件里的数据结构是dict类型,所以取值要按照键:值的形式:
<>强预处理数据
上面读出来的数据是ndarray类型,为了方便数据的展示,我们可以将其转换为,熊猫的DataFrame:
