debugging – filename and line number of Python script

debugging – filename and line number of Python script

Thanks to mcandre, the answer is:

#python3
from inspect import currentframe, getframeinfo

frameinfo = getframeinfo(currentframe())

print(frameinfo.filename, frameinfo.lineno)

Whether you use currentframe().f_back depends on whether you are using a
function or not.

Calling inspect directly:

from inspect import currentframe, getframeinfo

cf = currentframe()
filename = getframeinfo(cf).filename

print This is line 5, python says line , cf.f_lineno 
print The filename is , filename

Calling a function that does it for you:

from inspect import currentframe

def get_linenumber():
    cf = currentframe()
    return cf.f_back.f_lineno

print This is line 7, python says line , get_linenumber()

debugging – filename and line number of Python script

Handy if used in a common file – prints file name, line number and function of the caller:

import inspect
def getLineInfo():
    print(inspect.stack()[1][1],:,inspect.stack()[1][2],:,
          inspect.stack()[1][3])
