LM Installing

If you don’t yet have a development tool installed for working with Python on your computer, you can use Thonny. Thonny is a very simple and beginner-friendly Python environment, ideal for new learners.

Alternatively, you can use Visual Studio Code, PyCharm, or RStudio.

Here is a detailed installation guide for Thonny.

Installing Thonny (Beginner-Friendly Python IDE)

Thonny is a simple development environment designed for Python beginners.
The installation is quick and easy.

1. Download Thonny

  1. Open the website: https://thonny.org
  2. Click Download Thonny for Windows.
  3. Download the installer file (e.g., thonny-4.x.x.exe).

2. Run the Installer

  1. Double-click the downloaded file.
  2. Choose Next → Install.
  3. Keep the default settings.

3. Python Selection on First Start

If Python is not installed:

  • Select “Use Thonny’s built-in Python”
    → Recommended for beginners
    → Python will be installed automatically

If Python is already installed:

  • Either use Thonny’s built-in Python (recommended), or
  • Choose your existing Python installation.

4. Test the Installation

  1. Open Thonny.
  2. Type:
print("Hello Python!")
  1. Press Run ▶.

If Hello Python! appears, Thonny is working correctly.

Installing Python Packages in Thonny
(Example: pandas and matplotlib)

5. Install pandas or matplotlib

  1. Open Thonny.
  2. Go to: Tools → Manage packages…

  3. In the search box, type:

    • pandas
    • or matplotlib
  4. Click Search, then Install.

Thonny will download and install the package automatically.

6. Test if the packages work

Test pandas:

import pandas as pd
print(pd.__version__)

Test matplotlib:

import matplotlib.pyplot as plt
plt.plot([1, 2, 3], [3, 1, 4])
plt.show()

If a plot window appears, matplotlib is installed correctly.

Done!

You can now use Thonny to write Python programs and visualize data using packages like pandas and matplotlib.

If you are using RStudio, Visual Studio Code, or PyCharm as your Python environment,
please install the package matplotlib before the next session.

Installing matplotlib for Your Python Environment

👉 Installation via pip (recommended)

Open your terminal or command prompt and run:

pip install matplotlib

If you have multiple Python versions installed, you may need to run:

python -m pip install matplotlib

🔄 Restart Required

After installing a new Python package, it is usually necessary to restart your editor
(e.g., Visual Studio Code, RStudio, PyCharm).
Otherwise, the environment may not detect the newly installed package.

✔ Test whether matplotlib works

import matplotlib.pyplot as plt
plt.plot([1, 2, 3], [3, 1, 4])
plt.show()
