First, preface

Python is a high-level programming language for interpreting, object-oriented, and dynamic data types.

1. Many shell scripts can't handle or handle inconvenient things python can do
2. Python code is simple, simple to configure, various open source Escudo
3. High efficiency, high cost performance

Second, download the installation

2.1 Decompression

1) XZ

XZ is a lossless data compression file format using the LZMA compression algorithm (high compression rate)

XZ-D file. xz      -z file         # forced compression

2) Tar

tar zcvf file. Tar . GZ    # Package folder or file tar zxvf file. tar. GZ    # Unzip

File suffix if no. gz means that no gzip compression is used, just remove the parameter z of the TAR command
