In this short guide, I’ll show you how to install a package in Python using PIP. I will also demonstrate how to uninstall a package that is no longer needed.
If you’re using Windows, you’ll be able to install a Python package by opening the Windows Command Prompt, and then typing this command:
pip install package name
Note: The above method would only work if you already added Python to Windows path. Don’t worry if you don’t know what it means, as in the next section, I’ll cover the full steps to install a package in Python using PIP.
Here are the topics to be reviewed:
- Simple example with the steps to install the pandas package
- Uninstall a Python package
- Tool that will allow you to easily install/uninstall Python packages
Steps to Install a Package in Python using PIP
(1) First, type Command Prompt in the Windows search box.
(2) Right click on the Command Prompt (i.e., the Windows Command Prompt, not the Python Command Prompt). Then, select Run as administrator.
By running the Command Prompt as an administrator, you’ll avoid any permission issues that you may come across when trying to install a package.
(3) In the Command Prompt, type “cd\” as this command will ensure that your starting point has only the drive name:
(4) Press Enter. Now you’ll see the drive name of C:\>
(5) Type cd followed by the path name where your Python Scripts folder is located (the Scripts folder should be located within the Python application folder, where you originally installed Python).
In my case, I installed Python 3.6 under the Program Files (x86). And the complete path where my Scripts folder is located is: C:\Program Files (x86)\Python36-32\Scripts
Once you retrieved the Python Scripts path, type the following in the Command Prompt (do not forget to type the “cd” portion before the Python Scripts path):
(6) Press Enter, and you’ll see the following:
(7) Now, type the pip install command to install your Python package. The pip install command has the following structure:
pip install package name
Since in our case, we would like to install the pandas package, then you’ll need to type the following command in the Command Prompt:
pip install pandas
(8) Finally, press Enter, and you’ll notice that the package (here it’s pandas) will be installed:
You can check if the package was successfully installed in Python, by opening the Python IDLE and then running the command “import pandas”
If no errors appear (after you press F5 to run the import command), then the package has been successfully installed!
If you’re dealing with Anaconda, you may also want to check how to install a package using Anaconda.
Uninstall a Package using PIP
To uninstall a package using PIP, simply type the following command in the Command Prompt (do not forget to set the Python Scripts path before you type this command):
pip uninstall package name
In our case, type: pip uninstall pandas and then press Enter:
Finally, type y and then press Enter in order to proceed with the removal of the package:
Tool to install/uninstall a Python Package
Now I’ll share with you the code to install/uninstall Python packages using a simple tool I created.
Note that you’ll need to add Python to Windows path before you can start using the tool.
Here is the full Python code:
import os import tkinter as tk root= tk.Tk() canvas1 = tk.Canvas(root, width = 300, height = 350, bg = 'gray90', relief = 'raised') canvas1.pack() label1 = tk.Label(root, text='Type Package:', bg = 'gray90') label1.config(font=('helvetica', 14)) canvas1.create_window(150, 80, window=label1) entry1 = tk.Entry (root, width=27) canvas1.create_window(150, 120, window=entry1) def installPackage (): global installPythonPackage installPythonPackage = 'pip install ' + entry1.get() os.system('start cmd /k ' + installPythonPackage) def uninstallPackage (): global uninstallPythonPackage uninstallPythonPackage = 'pip uninstall ' + entry1.get() os.system('start cmd /k ' + uninstallPythonPackage) button1 = tk.Button(text=' Install Package ', command=installPackage, bg='green', fg='white', font=('helvetica', 12, 'bold')) canvas1.create_window(150, 180, window=button1) button2 = tk.Button(text=' Uninstall Package ', command=uninstallPackage, bg='coral3', fg='white', font=('helvetica', 12, 'bold')) canvas1.create_window(150, 230, window=button2) root.mainloop()
Simply run the code in Python and you should see the following screen:
Type the package name that you’d like to install or uninstall. For example, type the package name pandas, and then click on the green button to install the package:
That’s it! You should be able to enjoy the pandas package!
