Detailed guide to installing pip in Python2, simple and easy to understand!

Concise and easy to understand! Detailed tutorial on installing pip for Python2!

Introduction:
Python is a flexible, powerful and widely used programming language. There are many advantages to developing in Python, one of which is the rich set of third-party libraries that can be used to extend its functionality. To install these third-party libraries, you need to use pip, which is Python's package management tool. This article will introduce in detail how to install pip in a Python2 environment and provide specific code examples.

Step 1: Confirm the Python environment
First, we need to confirm that the Python environment has been installed. Open a terminal or command prompt and enter the following command:

python --version

If the version number displayed is Python 2.x.x, then congratulations, you already have a Python2 environment. If not, you need to install Python2 first.

Step 2: Download get-pip.py
Use pip to install pip. This may be the first time I have heard of it. Download get-pip.py to obtain the pip installation file. Open the browser and visit the following link: https://bootstrap.pypa.io/get-pip.py

Step 3: Run get-pip.py
This step requires the use of a terminal or command prompt to run get-pip.py. Open a terminal or command prompt and switch to the directory where get-pip.py is located. Run the following command:

python get-pip.py

This will run the get-pip.py script and automatically install pip.

Step 4: Verify installation
In order to confirm that pip has been successfully installed, we can use the following command to check the version of pip:

pip --version

If the version number displayed is pip 20.x.x ( python 2.x), then congratulations on your successful installation of pip.

Step 5: Upgrade pip (optional)
For some old versions of pip, some problems may occur during use. To solve these problems, after installing pip, we can upgrade it. Run the following command:

pip install --upgrade pip

This will upgrade the installed pip to the latest version.

Conclusion:
This article provides you with a detailed tutorial on installing pip, and uses specific code examples to make it easier for you to understand and operate. As a Python package management tool, pip provides you with a convenient way to install third-party libraries, allowing you to develop Python programming more efficiently. Hope this tutorial helps you!
