如何在Windows，Linux和Mac中檢查Python版本
This post is all about how to check Python version on your computer. But before getting started, let’s know a bit about Python.
這篇文章全部關於如何在您的計算機上檢查Python版本。 但是在開始之前，讓我們對Python有一點了解。
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是最流行的編程語言之一。 而且由於其強大的開發人員社區，您可以輕鬆地看到很多不同的版本被頻繁發佈。
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.
到目前爲止，有兩個最受歡迎的Python版本，一個是Python 2.7.x ，另一個是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.
有時您必須使用僅支持Python 2.7的python庫，有時我們必須使用Python 3.x版本，但我們安裝了Python 2.7，並且我們可能會發現我們的庫不支持已安裝的python版本。
In that case, it’s best to check the version of Python installed before downloading the required library.
在這種情況下，最好在下載所需的庫之前檢查安裝的Python版本。
In this tutorial, we will see how to check the python version on Windows, Linux and macOS just with the help of terminal.
在本教程中，我們將看到僅在終端的幫助下如何在Windows，Linux和macOS上檢查python版本。
Now, before getting started, you should be able to access your command-line of your OS.
現在，在開始之前，您應該能夠訪問操作系統的命令行。
Note: This post is all about checking the version of python installed on your computer and in case of windows, most of the time, a windows installation do not have python pre-installed.
注意 ：這篇文章全是關於檢查計算機上安裝的python版本的，對於Windows，大多數情況下，Windows安裝中沒有預安裝python。
