How to Run Python in Ubuntu 24.04 LTS Linux | Step-by-Step Guide
Running Python on Ubuntu 24.04 LTS is straightforward, thanks to Python being pre-installed on most Linux distributions. This guide will walk you through verifying your Python installation, running Python scripts, and installing additional packages if needed. Follow these steps to start coding in Python on your Ubuntu 24.04 LTS system.
*Step-by-Step Instructions:*
*Step 1: Open Terminal*
1. Press `Ctrl + Alt + T` or search for "Terminal" in the Applications menu to open a terminal window.
*Step 2: Check Python Installation*
1. To check if Python is already installed, type the following command and press Enter:
```bash
python3 --version
```
2. You should see output indicating the version of Python installed, such as `Python 3.x.x`. If Python is not installed, you can install it using the following steps.
*Step 3: Install Python (If Necessary)*
1. Update your package list to ensure you have the latest information on available packages:
```bash
sudo apt update
```
2. Install Python by running:
```bash
sudo apt install python3
```
3. Verify the installation by checking the version again:
```bash
python3 --version
```
*Step 4: Running Python Interactively*
1. To start an interactive Python session, simply type:
```bash
python3
```
2. This will open the Python interpreter, and you can start writing Python commands directly. For example:
```python
print("Hello, World!")
```
3. To exit the interactive session, type:
```python
exit()
```
or press `Ctrl + D`.
*Step 5: Creating and Running Python Scripts*
1. Use a text editor to create a Python script. You can use editors like `nano`, `vim`, or graphical editors like `Gedit` or `VS Code`. For simplicity, let's use `nano`:
```bash
nano hello.py
```
2. In the editor, write your Python script. For example:
```python
hello.py
print("Hello, Ubuntu!")
```
3. Save and exit the editor. In `nano`, you can do this by pressing `Ctrl + X`, then `Y` to confirm, and `Enter` to save.
*Step 6: Run the Python Script*
1. To run the Python script you just created, use the following command:
```bash
python3 hello.py
```
2. You should see the output:
```
Hello, Ubuntu!
```
*Step 7: Installing Python Packages*
1. Python packages can be installed using `pip`, the Python package installer. First, ensure `pip` is installed:
```bash
sudo apt install python3-pip
```
2. To verify the installation of `pip`, type:
```bash
pip3 --version
```
3. Install packages using `pip3`. For example, to install the `requests` library:
```bash
pip3 install requests
```
*Additional Tips:*
**Virtual Environments**: Use virtual environments to manage dependencies for different projects separately. Create a virtual environment with:
```bash
python3 -m venv myenv
```
Activate the virtual environment with:
```bash
source myenv/bin/activate
```
Deactivate with:
```bash
deactivate
```
**IDEs and Editors**: For a more robust coding experience, consider using an Integrated Development Environment (IDE) like PyCharm, or a text editor like Visual Studio Code with Python extensions.
By following these steps, you can easily run Python on your Ubuntu 24.04 LTS system, manage packages, and start developing your projects. Happy coding!
