这篇文章全部关于如何在您的计算机上检查Python版本。 但是在开始之前，让我们对Python有一点了解。
Python is one of the most popular programming languages. And due to its awesome developer community, you can easily see a lot of different versions getting released quite frequently.
Python是最流行的编程语言之一。 而且由于其强大的开发人员社区，您可以轻松地看到很多不同的版本被频繁发布。
There are two most popular versions of Python as of now, one is Python 2.7.x and the other is Python 3.8.x.
到目前为止，有两个最受欢迎的Python版本，一个是Python 2.7.x ，另一个是Python3.8.x 。
Sometimes you have to work with python library that only supports Python 2.7 and sometimes we have to work with Python 3.x version but we have Python 2.7 installed and we may find our library not supporting the installed version of python.
有时您必须使用仅支持Python 2.7的python库，有时我们必须使用Python 3.x版本，但我们安装了Python 2.7，并且我们可能会发现我们的库不支持已安装的python版本。
In that case, it’s best to check the version of Python installed before downloading the required library.
在这种情况下，最好在下载所需的库之前检查安装的Python版本。
