getting source line number

[snippsat]

Yes can use inspect for this.
Can make a function,then insert that function call will print line number.

import inspect

def line_numb():
   '''Returns the current line number in our program'''
   return inspect.currentframe().f_back.f_lineno

# print a message with source line number
n = 2 ; print('variable {} is at line {}'.format(n, line_numb()))
print('now printing at line {}'.format(line_numb()))

Output:
variable 2 is at line 8
now printing at line 9
