Python - print() - debugging -show file and line number

Question

When using print() in python, is it possible to print where it was called? So the output will look like var_dump in php with xdebug. Eg. I have script D:\Something\script.py, and at line 50, there is a print("sometest"), so the output will look like this:

D:\Somethinq\script.py:50 sometest

Or is there any module that could achieve this? In large projects, it's really hard to manage where these prints came from.

So, using answers provided in filename and line number of python script , this function can be called instead of print(), and prints line number before every output:

from inspect import currentframe

def debug_print(arg):
    frameinfo = currentframe()
    print(frameinfo.f_back.f_lineno,":",arg)
