How to Execute Python Script in Linux
How to Execute a Python Script in Linux 🐧🐍
1️⃣ Why Run Python Scripts on Linux? 🤔
Linux is a preferred platform for developers due to its stability, flexibility, and support for automation. Running Python scripts on Linux allows seamless automation, data processing, and software development. 🚀
2️⃣ Check If Python is Installed 🧐
Most Linux distributions come with Python pre-installed. To check:
python3 –version
If Python is not installed, install it using:
sudo apt update && sudo apt install python3
For Red Hat-based systems:
sudo yum install python3
3️⃣ Writing a Simple Python Script 📝
Create a Python file using any text editor like nano, vim, or VS Code.
nano myscript.py
Add the following Python code:
print(“Hello, Linux!”)
Save and exit (CTRL+X → Y → ENTER in nano).
4️⃣ Running a Python Script 🔄
Execute the script using:
python3 myscript.py
This runs the script using Python 3. If you are using Python 2 (deprecated), replace python3 with python.
5️⃣ Making the Script Executable 🎯
To run the script without typing python3, make it executable:
chmod +x myscript.py
Now, execute it directly using:
./myscript.py
6️⃣ Using the Shebang Line 🚀
Modify the script to include a shebang line at the top:
#!/usr/bin/env python3
print(“Hello, Linux!”)
This tells Linux to execute the script using Python 3.
7️⃣ Running Python Scripts in the Background 🏗️
To run a script in the background, use:
python3 myscript.py &
To keep it running even after logging out, use nohup:
nohup python3 myscript.py &
8️⃣ Scheduling Python Scripts with Cron ⏳
Automate script execution using cron jobs:
crontab -e
Add a new job (e.g., run every day at 10 AM):
0 10 * * * /usr/bin/python3 /path/to/myscript.py
Save and exit.
9️⃣ Handling Errors & Debugging 🐞
If a script fails, check error messages:
python3 myscript.py
Use debugging tools like pdb:
python3 -m pdb myscript.py
