Как запустить скрипт Python на Linux 🐧

1. Откройте терминал.
2. Перейдите в каталог, где находится ваш скрипт, с помощью команды cd.
3. Убедитесь, что ваш скрипт имеет исполняемые разрешения. Если нет, можете использовать команду chmod +x script.py
4. Запустите скрипт, введя команду python script.py, где script.py - это имя вашего скрипта.

Running Python Script on Linux

Python is a versatile programming language that is widely used for various purposes, including script execution. Running Python scripts on Linux is a straightforward process that requires a few simple steps. In this article, we will explore how to run a Python script on Linux, providing detailed explanations and code examples along the way.

Step 1: Install Python

To run a Python script on Linux, you first need to ensure that Python is installed on your system. Most Linux distributions come with Python pre-installed, but it's always a good idea to check the version. Open the terminal and type the following command:

python --version

If Python is not installed, you can install it using the package manager specific to your Linux distribution. For example, on Ubuntu, the following command installs Python 3:

sudo apt-get install python3

Step 2: Create a Python Script

Once you have Python installed, you can create a Python script using any text editor. Let's create a simple "hello.py" script that prints "Hello, World!" to the console. Open your preferred text editor and enter the following code:

print("Hello, World!")

Save the file with a ".py" extension, for example, "hello.py". Make sure to remember the location where you saved the script.

Step 3: Make the Script Executable

To run a Python script directly from the command line, you need to make it executable. This can be done by granting execute permissions to the script file. Open the terminal and navigate to the directory where your script is located using the "cd" command:

cd /path/to/script/directory

Once inside the directory, use the following command to make the script executable:

chmod +x hello.py

Now, you can execute the script by simply typing "./hello.py" in the terminal.

Step 4: Execute the Python Script

To execute the Python script on Linux, open the terminal and navigate to the directory where the script is located. Use the following command to run the script:

./hello.py

Your Python script will be executed, and you should see the output "Hello, World!" displayed in the terminal.

Additional Tips

Here are some additional tips and considerations when running Python scripts on Linux:

• Ensure that the Python interpreter is added to the system's PATH variable. This allows you to run Python scripts from any directory without specifying the full path to the interpreter.
• If your Python script requires external libraries or modules, make sure they are installed on your system. You can use package managers such as pip to install Python packages.
• If you encounter any errors while running the script, carefully review the code for syntax errors or missing dependencies. The terminal will usually provide helpful error messages to assist in troubleshooting.

That's it! You now have a comprehensive understanding of how to run a Python script on Linux. Remember to follow the provided steps and use the necessary commands to ensure a smooth execution of your Python script.
