You can start a Python program with the terminal or command line. This works on all platforms (Mac OS, Windows, Linux).,To start the program, we have to open the command line and type:,To open a terminal on Windows: press the windows key + r key (run program), type cmd or command and press enter.,On Mac OS use finder to start a terminal. You can hit command+space and type terminal, then hit enter.

In your Terminal, run this file with using the following command, and you should see the corresponding output:,In your Terminal, run this file. You will see the following error:,In this article, we will look at the various ways to execute shell commands in Python, and the ideal situation to use each method.,Running this file produces the following output:

import os os.system("echo Hello from the other side!") 

In your Terminal, run this file with using the following command, and you should see the corresponding output:

$ python3 echo_adelle.py Hello from the other side! 

Let’s create a new file called cd_return_codes.py and type the following:

import os home_dir = os.system("cd ~") print("`cd ~` ran with exit code %d" % home_dir) unknown_dir = os.system("cd doesnotexist") print("`cd doesnotexis` ran with exit code %d" % unknown_dir) 

In this script, we create two variables that store the result of executing commands that change the directory to the home folder, and to a folder that does not exist. Running this file, we will see:

$ python3 cd_return_codes.py `cd ~` ran with exit code 0 sh: line 0: cd: doesnotexist: No such file or directory `cd doesnotexist` ran with exit code 256 

In a new filed called list_subprocess.py , write the following code:

import subprocess list_files = subprocess.run(["ls", "-l"]) print("The exit code was: %d" % list_files.returncode) 

Run this file and your console’s output would be similar to:

$ python3 list_subprocess.py total 80 [email protected] 1 stackabuse staff 216 Dec 6 10:29 cd_return_codes.py [email protected] 1 stackabuse staff 56 Dec 6 10:11 echo_adelle.py [email protected] 1 stackabuse staff 116 Dec 6 11:20 list_subprocess.py The exit code was: 0 

Now let’s try to use one of the more advanced features of subprocess.run() , namely ignore output to stdout . In the same list_subprocess.py file, change:

list_files = subprocess.run(["ls", "-l"]) 

list_files = subprocess.run(["ls", "-l"], stdout=subprocess.DEVNULL) 

The standard output of the command now pipes to the special /dev/null device, which means the output would not appear on our consoles. Execute the file in your shell to see the following output:

$ python3 list_subprocess.py The exit code was: 0 

What if we wanted to provide input to a command? The subprocess.run() facilitates this by its input argument. Create a new file called cat_subprocess.py , typing the following:

import subprocess useless_cat_call = subprocess.run(["cat"], stdout=subprocess.PIPE, text=True, input="Hello from the other side") print(useless_cat_call.stdout) # Hello from the other side 

Running this file produces the following output:

Hello from the other side 

We can also raise an Exception without manually checking the return value. In a new file, false_subprocess.py , add the code below:

import subprocess failed_command = subprocess.run(["false"], check=True) print("The exit code was: %d" % failed_command.returncode) 

In your Terminal, run this file. You will see the following error:

$ python3 false_subprocess.py Traceback (most recent call last): File "false_subprocess.py", line 4, in failed_command = subprocess.run(["false"], check=True) File "/usr/local/python/3.7.5/Frameworks/Python.framework/Versions/3.7/lib/python3.7/subprocess.py", line 512, in run output=stdout, stderr=stderr) subprocess.CalledProcessError: Command '['false']' returned non-zero exit status 1. 

By default, subprocess.Popen does not stop processing of a Python program if its command has not finished executing. In a new file called list_popen.py , type the following:

import subprocess list_dir = subprocess.Popen(["ls", "-l"]) list_dir.wait() 

The poll() method returns the exit code if a command has finished running, or None if it’s still executing. For example, if we wanted to check if list_dir was complete instead of wait for it, we would have the following line of code:

In a new file called cat_popen.py , add the following code snippet:

import subprocess useless_cat_call = subprocess.Popen(["cat"], stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True) output, errors = useless_cat_call.communicate(input="Hello from the other side!") useless_cat_call.wait() print(output) print(errors)

OS X’s standard console is a program called Terminal. Open Terminal by navigating to Applications, then Utilities, then double-click the Terminal program. You can also easily search for it in the system search tool in the top right.,Press Enter and see what happens. After showing the results, Python will bring you back to the interactive prompt, where you could enter another command:,The command line Terminal is a tool for interacting with your computer. A window will open with a command line prompt message, something like this:,If you haven’t yet got python, the latest official installation packages can be found here:

window-terminal is a Python module for start new Terminal Window with print and input control.

pip install window-terminal

Below there are example, how to use this module.

import time from window_terminal import WindowTerminal #### First Example: Print on Windows Terminal #### # To instantiate a Window Terminal call 'WindowTerminal.create_window()' window1 = WindowTerminal.create_window() # To Open a Window Terminal, call 'open()' from a object window1.open() # Print on Windown Terminal, call 'print()' window1.print('Hello I\'m a Window Terminal!') # The Window Terminal can be closed at any time # For example: close after 3 seconds time.sleep(3) window1.close() #### Second Example: Interact with Window Terminal #### # Insantiating and opening it more. window2 = WindowTerminal.create_window() window2.open() # And printing. window2.print('### Welcome to Window Terminal 2 ###') # To prompt for something to Window Terminal call 'input()' # Current thread will be blocked until input is answered something = window2.input('Type something here: ') # Priting result. print('Window Temrinal 2 replied:', repr(something)) # Closing Window Terminal 2 window2.close() #### Third Example: Async Interact with Window Terminal #### # # Insantiating and opening it for the last time. window3 = WindowTerminal.create_window() window3.open() # We can define a function to be called when input is answered def input_callback(result): print('Window Terminal 3 repled:', repr(result)) # Now, current thread not will be blocked, when 'input()' is called window3.input('Other input, type something more here: ', input_callback) # To prevent the script from closing, call 'wait_close()' to block # current thread, until Window Terminal close (for example: user action). window3.wait_close() # Printing after Window Terminal 3 close print('Window Terminal 3 was closed!')

Pull requests are welcome. For major changes, please open an issue first to discuss what you would like to change.

Please make sure to update tests as appropriate.
