Where to download python

Where to download python? The Python language can be used across platforms, and the download and installation can also be divided into two versions: Windows and Linux.

linux:

Usually Python is installed in /usr/local/python3 (the specific installation location depends on personal preference, but remember to install location), because the directory python3 does not exist in the /usr/local directory, so create a new directory first:

mkdir /usr/local/python3

1. Download Python3 from the official website

https://www.python.org/downloads/

2. Install dependency environment

Installing Python3 requires these four dependencies: gcc, zlib, zlib-devel, openssl-devel

Then install these four software respectively:

yum install gcc -y

yum install zlib -y

yum install zlib-devel -y

yum install openssl-devel -y

3. Unzip the downloaded Python3 installation package

Because the /opt directory is third-party software storage directory, so we move the downloaded installation package to the /opt directory, and then execute the decompression command in the directory:

tar -zvxf Python-3.6.4.tgz ##My installation package is 3.6 .4 of.

4. Compile and install

Enter the decompressed directory and compile in the directory. (Be sure to compile in the decompressed directory, otherwise it will not compile)

cd Python-3.6.4

./configure --prefix=/usr/local/ python3 ##Pay attention to the decimal point symbol. --prefix is ​​to specify the installation directory. The installation directory specified here is /usr/local/python3

make && make install
