In such a case, it will make no variance, since you are changing all the things using an empty string (Despite the fact that it would be improved to work with s+ from an performance viewpoint).

Regrettably, contrary to in printf, You can not offer the sector with being a run time argument:
This really is quite normal mistake-examining code for a Python script that accepts command-line arguments.
The primary difference lies in just how it get's taken care of. For those who might have a group of (for instance) three Areas immediately subsequent one another s+ can take that group and turns The complete it right into a "", although s would proces each House on its own.
