How to find out the line in which the python code was executed?

Question

Python

Hello.

Here is a sample code: in this case, the statement "print('hehe')" is in the 2nd line, how to display what is the second line? In php, for example, there is a "magic constant" __LINE__ for this. For example: In python, it should also be like that, but how?

print('hehe')


echo 'hehe ' . __LINE__; // выведет "hehe 2"

1) You can include the Logging package ( Logging in Python )
2) You can use something like this:

def debug(msg):
     import sys
     frame = sys._getframe(1)

     name = frame.f_code.co_name
     line_number = frame.f_lineno
     filename = frame.f_code.co_filename

     return 'File "%s", line %d, in %s: %s' % (filename, line_number, name, msg)

print(debug('hehe'))

At the output we get:

File "/home/sergey/Рабочий стол/Projects/l.py", line 12, in <module>: hehe
