Python profiling an inner function

Question

I am trying to profile a part of my program. The pattern is like the following:

def de():
      def abc():
         print("123")
      cProfile.run('abc()')

When I am trying to run this program, I got an error: File "", line 1, in NameError: name 'abc' is not defined

Is there anyway to work around this error?

Answer 1

Everything happening outside of the function, meaning that they are hidden from the global scope.

use runctx(). Please read https://docs.python.org/3/library/profile.html#profile.runctx

import cProfile

def de():
      def abc():
         print("123")
      cProfile.runctx('abc()', None, locals=locals())

de()

output:

"123"
5 function calls in 0.000 seconds

Answer 2

Just for completeness: in your case you could also do

def de():
    def abc():
        print("123")
    cProfile.run(abc.__code__)

de()

(creates the same output as the runctx variant)
