Adding Macros to Python

Question

I would like to invoke the following code in-situ wherever I refer to MY_MACRO in my code below.

# MY_MACRO
frameinfo = getframeinf         


        

Answer 1

How about a function you can call? This function accesses the caller's frame, and rather than using locals(), uses frame.f_locals to get the caller's namespace.

def my_function():
    frame = currentframe().f_back
    msg = 'We are on file {0.f_code.co_filename} and line {0.f_lineno}'.format(frame)
    current_state = frame.f_locals
    print current_state['some_variable']

Then just call it:

def some_function:
    my_function()

def some_other_function:
    some_function()
    my_function()

class some_class:
  def some_method:
     my_function()
