How to quickly install Python3 with pip

A quick way to install pip for Python3 requires specific code examples

When using Python for development, we often use third-party libraries to enhance our development efficiency . Pip is a package management tool for Python that can help us quickly install and manage various Python libraries.

However, in some cases, we may find that pip is not pre-installed in our Python environment, and we need to install pip manually. Below is a quick way to install pip, with specific code examples.

Step 1: Download the get-pip.py script

First, you need to download the get-pip.py script on the official Python website. Open https://bootstrap.pypa.io/get-pip.py in your browser and save it locally.

Step 2: Execute the get-pip.py script

Open the command prompt or terminal and switch to the folder directory where get-pip.py is located. Use the following command to execute the get-pip.py script:

python get-pip.py

If you have both Python2 and Python3 environments, make sure you are using the Python3 interpreter to execute this script.

Step 3: Verify whether pip is installed successfully

Enter the following command in the command prompt or terminal:

pip --version

If you see To output similar to "pip 20.0.2 from c:usersusername ppdatalocalprogramspythonpython38libsite-packagesspip (python 3.8)", then congratulations, pip has been successfully installed!

Through the above three simple steps, we can quickly install pip. The following is a specific code example:

import urllib.request
import ssl
import os

ssl._create_default_https_context = ssl._create_unverified_context

url = 'https://bootstrap.pypa.io/get-pip.py'
file_name = 'get-pip.py'

urllib.request.urlretrieve(url, file_name)

os.system('python get-pip.py')

By running the above code, you can automatically download and install pip. After executing the script, you can enter the pip --version command in the command prompt or terminal to verify whether pip is installed successfully.

To sum up, installing pip only requires three simple steps: download the get-pip.py script, execute the script, and verify the installation. I hope this article can help you quickly install pip and make it more convenient for you to use Python development!
