Under Record How to install a specific version of python on a Linux system. (I did not think you Nongmeitaiyan also took out a forest). I am here roughly divided into two major steps:
1. obtain the installation package
1.1 raspberries come in with a browser, you can download directly from the official website. URL's official website is:
www.python.org
After entering the page, click on " Downloads " in this column, select "in the drop-down menu Source code ."
1.2 Select the version of the XZ Compressed Source tarball , that can be compiled archive version.
1.3 find their favorite python version in the next page. Here with Python 3.7.0 , for example, click on " the Download ." This is only a dozen MB, overall or quickly.
1.4 Raspberry Pi download something from the browser are automatically saved in the path / home / Downloads folder, which is shown below:
Of course you can also use the command line to enter this path:
