If you thought nothing gets easier than learning Python, executing Python programs is even easier.
To run the python program, all you have to do is follow the given command syntax:
python3 Filename.pyAnd if you are running python2, you use only python instead of python3.
You may use dedicated IDEs like PyCharm for a more immersive Python coding experience, but this is sufficient for running a couple of Python scripts.
Let's see it in more detail.
Run Python program in Ubuntu command line
For your reference, I will be using the following Python code throughout this tutorial:
print('Hello Ubuntu users, greetings from sagar sharma')Yes, that's a simple hello-world python program that is saved as hello.py in my system.
To execute the program, all you have to do is append the filename to the python3 command and that's it:
python3 Filename.pyAs I mentioned earlier, I will be using hello.py so my command will be:
python3 hello.py
And that's it!
Run Python program as a script in Ubuntu command line
You might not want to use the python3 command just for executing the python program.
In that case, you can call the interpreter to do the work for you!
But to do so, you will have to make a slight change in your existing code.
You will have to add the following line at the beginning of your python code:
#!/usr/bin/env python3
Once you do that, you will have to make this file executable using the chmod command:
chmod +x Filename.pyAnd finally, you can execute the python program as a script:
./Filename.py
And as you can see, the program was executed the same way as you execute shell scripts.
