Parse errors on exec() calls

[MikeTheWatchGuy]

I'm getting this error when I attempt to run pasteurize on my code:

c:\Python\PycharmProjects\GooeyGUI\Pasture>pasteurize -w PySimpleGUI.py
RefactoringTool: Can't parse PySimpleGUI.py: ParseError: bad input: type=1, value='exec', context=(' ', (10134, 33))
RefactoringTool: No files need to be modified.
RefactoringTool: There was 1 error:
RefactoringTool: Can't parse PySimpleGUI.py: ParseError: bad input: type=1, value='exec', context=(' ', (10134, 33))

I've been able to get around most incompatible problems by adding this if statement:

if sys.version_info[0] >= 3:
   # do version 3 stuff here
else:
   # do version 2 stuff here

It's been working GREAT so far and it's allowed me to ship both Python 2.7 and Python 3 versions of PySimpleGUI.

My if statement trick doesn't work on this exec call.

Here is the code that is failing:

            try:
                result = eval('{}'.format(cmd), myglobals, mylocals)
            except Exception as e:
                if sys.version_info[0] < 3:
                    result = 'Not available in Python 2'
                else:
                    try:
                        result = exec('{}'.format(cmd), myglobals, mylocals)
                    except Exception as e:
                        result = 'Exception {}\n'.format(e)

I've also tried defining my own exec function if it's version 2, but it still fails with this error.

Is there a way to make exec calls in Python 2 or a way to have the parser ignore this statement?
