<pre class="hljs vim mCustomScrollbar _mCS_11 mCS-autoHide mCS_no_scrollbar">The system python on <strong>CentOS 7</strong> must be the <strong>2.7</strong> version that we ship. Must. <br>You cannot replace the system python with a different one. <br>If you need a newer python then multiple places ship a python3 stack that installs in parallel to the system 2.7 that we ship. <br>No-one yet ships 3.8 as it's too new. There are python 3.6 packages in the <strong>CentOS 7.7</strong> base and updates repos. <br>Use those. <br>They are supported and are the same versions that are in <strong>CentOS 8</strong> so you know things written on one should work on the other.<br><br> -------------------</pre>

<p><span class="bjh-p"><strong>Python 3</strong> is now available. Installing the python3 package gives you the Python 3.6 interpreter。Python 3 可用，安装python3将会提供Python 3.6解释器。</span></p>
