Preface

Hello . Here is Python Reptiles from getting started to giving up series of articles . I am a SunriseCai.

Tool introduction

It is said that : A good workman does his work well 、 You must sharpen your tools first . This is also true when it comes to coding . In the process of writing code, it is necessary to find a tool to weigh hands . Here are two tools I use —Anaconda and PyCharm.

Anaconda、PyCharm The role of :

Tools effect
Anaconda An open source Python Release version , Integrated a lot about python Third party Library of Scientific Computing

Anaconda:

  • Anaconda It's a common package of data science Python Release version . It comes with Python etc. 150 Multiple science packs and their dependencies . In a word, the conclusion is : convenient !!

PyCharm:

  • PyCharm With a complete set can help users in using Python A tool to improve the efficiency of language development , Such as debugging 、 Syntax highlighting 、Project management 、 Code jump 、 Smart tips 、 Done automatically 、 unit testing 、 version control .

So computer configuration Python Reptiles Operating environment , Just install Anaconda+PyCharm That's all right. . Let's talk about how to install these two software .
