title: Difference between the python in Anaconda and original one
body: <p>I'm a windows user and I've already installed the python (which is version 3.6) on my computer. Then I downloaded the Anaconda and when I open the Anaconda prompt to run python, it gives python version3.7</p>
  
  <p>However, if I directly use the cmd to run python, it still appeared to be version 3.6     . It seems there are 2 versions in my computer. As I can use some libraries in the anaconda prompt python but cannot use them in my original python. One thing I'm not very happy with is that the anaconda prompt runs much slower than cmd in my computer.</p>
  
  <p>So my question is: will there be any conflict between these two pythons and their libraries? If I want to use the libraries and packages embedded in anaconda, does it necessarily mean I can only use the anaconda prompt (but cannot use cmd in windows) to run my python file from now on?</p>
