There

Print the current filename and line.

Example, where.py

import there
import there as here

print(here)
print('and')
print(there)

Then python where.py will print:

where.py:4
and
where.py:6

replace print function

There provide a replacement for the print function, that prepend the filename and line.

Example, where.py

from there import print

print('hi')
print('there')

Then python where.py will print:

where.py:3 hi
where.py:4 there

that's it

That's it (for now), non more, no less. I have plan – the usually never get realised – to also have a there.indent that return the indentation of the current line.

Gotchas

Returns the line where the __str__, or __repr__ of there is computed. Usually by print. So it might be wrong. If you want to be sure (like when using log) wrap it in str()

Runs only on CPython likely. But anyway don't run it in production.
