Python3 shebang line

# This is the pyhton3 shebang line [https://en.wikipedia.org/wiki/Shebang_(Unix)]

#!/usr/bin/python3

# A shebang line defines where the interpreter is located. In this case, the python3 interpreter is located in /usr/bin/python3. A shebang line could also be a bash, ruby, perl or any other scripting languages' interpreter, for example: #!/bin/bash.

# Without the shebang line, the operating system does not know it's a python script, even if you set the execution flag (chmod +x script.py) on the script and run it like ./script.py. To make the script run by default in python3, either invoke it as python3 script.py or set the shebang line.

# You can use #!/usr/bin/env python3 for portability across different systems in case they have the language interpreter installed in different locations.
