Would be enough to have the source line text?
<code test1.py>
def extract_caller_info():
import sys, traceback
return traceback.extract_stack(sys._getframe(2), limit=1)
def f1(arg):
if capturecall:
print extract_caller_info()
# do_normal_stuff(arg)
def f2():
a,b,c = 1,0,3
return f1(a and (b or c))
capturecall = True
result = f2()
</code>
output is like this:
[('test1.py', 12, 'f2', 'return f1(a and (b or c))')]
source file name, line number, function name, source line text.

Tell your users that they'll have better results if those two calls are
split on different lines:
def f3():
return (f1(a and b)
or e
or f1(c and d))
Output:
[('test1.py', 18, 'f3', 'return (f1(a and b)')]
[('test1.py', 20, 'f3', 'or f1(c and d))')]
