To make a system call from your Python script, for example displaying the current version of Python3 using the command python3 --version, we need to use the import os module, and use the os.system function
Create a new file named system_call.py and copy and paste the code below
#!/usr/bin/python3
import os
os.system('python3 --version')
import os
os.system('python3 --version')
Then enter the following command to make the Python script executable
chmod +x system_call.py
Then run the script by the entering the command
./system_call.py
If everything works correctly the current version of Python3 will be display in the terminal
