This line is called a shebang and it tells the kernel which interpreter to use on the script.
For example, if a script is named with the path path/to/script, and it starts with the line #!/bin/sh, then the program loader is instructed to run the program /bin/sh, passing path/to/script as the first argument.
In your instance, the kernel will use whatever /usr/bin/python points to (I think it is by default python3.6).

/usr/bin/pythonshould be Python 2.7. This is per PEP 394, which says the commandpythonshould be Python 2.
