Setting Up a Python Environment

Overview

Python is a widely used interpretive, high-level, and general programming language. Python supports multiple programming paradigms, including structured, procedural, reflective object-oriented, and functional programming. It employs a dynamic type system and automatic garbage collection to manage memory efficiently. It has a large and comprehensive standard library. Its language structure and object-oriented method are designed to help programmers write clear, logical code for small and large projects.

This section describes how to set up a Python environment on an ECS.

Prerequisites

  1. The ECS has an EIP bound.
  2. The rule listed in the following table has been added to the security group which the target ECS belongs to. For details, see Adding a Security Group Rule.
