How to run a Python script in Ubuntu terminal?

To run a Python script in the Ubuntu terminal, you can follow these steps:

1. Open the terminal by clicking on the "Activities" menu in the top left corner of the screen and searching for "Terminal".
2. Navigate to the directory where you have saved your Python script using the cd command. For example, if your script is saved in the "Documents" folder, you can type cd Documents to navigate to that folder.
3. Once you are in the directory containing your Python script, you can run it by using the python command followed by the script name. For example, if your script is named "script.py", you can type python script.py to execute it.

Note: Ubuntu usually comes with Python 2.7 pre-installed. If you have both Python 2 and Python 3 installed, you may need to use the python3 command instead of python to run scripts written in Python 3. Example: python3 script.py.

Ensure that you have installed Python on your Ubuntu system before running the script. To install Python, you can use the following command in the terminal:

1

sudo apt-get install python3

Remember to replace python3 with python if you want to install Python 2.

What is the command to execute a Python program in Ubuntu?

To execute a Python program in Ubuntu, you can use the command:

1

python3 filename.py

Replace filename.py with the actual name of your Python script.

What are the system requirements to run Python on Ubuntu?

To run Python on Ubuntu, you need to meet the following system requirements:

1. Operating System: Ubuntu (any recent version)
2. Processor: 1 GHz or faster
3. RAM: At least 1 GB (recommended 2 GB or more)
4. Disk Space: At least 1.5 GB of free space (recommended 3 GB or more)
5. Python Interpreter: Python comes pre-installed with Ubuntu, but you can install a specific version using the package manager.

It's important to note that these requirements are basic and should be enough to run Python smoothly. However, if you are planning to work with resource-intensive applications or large datasets, you may need higher specs than the ones mentioned above.

What is the command to check Python version in Ubuntu terminal?

The command to check the Python version in the Ubuntu terminal is:

1

python3 --version

This command will display the installed Python version on your system.

How to install Python 3 instead of Python 2 on Ubuntu?

To install Python 3 instead of Python 2 on Ubuntu, you can follow these steps:

1. Open a terminal by pressing Ctrl+Alt+T or by searching for "Terminal" in the Ubuntu Dash.
2. Update the package list of your system by running the following command in the terminal: sudo apt update
3. Install Python 3 by running the following command: sudo apt install python3
4. Verify that Python 3 is installed correctly by checking its version: python3 --version
5. By default, the python3 command will be linked to the installed version of Python 3. If you want to specifically use python3 instead of python for Python 3 code, update the python symlink: sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 1

Now you have Python 3 installed on your Ubuntu system. You will have both Python 2 and Python 3 available, with the python command referring to Python 2 and the python3 command referring to Python 3.

How to handle Python version conflicts in Ubuntu?

Here are some steps you can follow to handle Python version conflicts in Ubuntu:

1. Check Python versions: Open terminal and type "python --version" to check the default Python version. Use "python3 --version" to check the default Python 3 version.
2. Choose a virtual environment solution: Decide if you want to use a virtual environment solution like virtualenv, pyenv, or conda.
3. Install and use virtualenv (example): Install virtualenv by running: "sudo apt install python3-venv" Create a new virtual environment: "python3 -m venv /path/to/new/virtual/environment" Activate the virtual environment: "source /path/to/new/virtual/environment/bin/activate" Now, any package installation or script execution will use this isolated environment with its own Python version.
4. Modify shebang line: If you want to execute a specific Python version directly, you can modify the shebang line of your Python script to use the desired Python version. For example, if you want to use Python 3.8, change the first line of the script to "#!/usr/bin/env python3.8".
5. Use aliases: Another approach is to create aliases for different Python versions. Open your terminal and edit your .bashrc file using a text editor: "nano ~/.bashrc" Add aliases by appending the following lines to the file (example): alias python3='python3.8' alias python='python2.7' Save the modified .bashrc file and exit. Reload the terminal or run "source ~/.bashrc" to apply the changes. Now, typing "python3" or "python" will execute the corresponding Python version.
6. Install other Python versions: Ubuntu usually comes with pre-installed Python versions. To see available versions, run "apt list python*". If you need additional versions, you can install them using apt or other package managers like pyenv. For example, to install Python 3.7, run "sudo apt install python3.7".

Remember to be cautious when modifying Python versions as it can affect system functionality or installed applications. Using virtual environments is generally recommended for isolating Python versions and dependencies.
