How do I stop execution inside exec command in Python 3?

Question

I have a following code:

code = """
print("foo")

if True: 
    return

print("bar")
"""

exec(code)
print('This should still be executed')

If I run it I get:

Traceback (most recent call last):
  File "untitled.py", line 10, in <module>
    exec(code)
  File "<string>", line 5
SyntaxError: 'return' outside function

How to force exec stop without errors? Probably I should replace return with something? Also I want the interpreter work after exec call.

Here, just do something like this:

class ExecInterrupt(Exception):
    pass

def Exec(source, globals=None, locals=None):
    try:
        exec(source, globals, locals)
    except ExecInterrupt:
        pass

Exec("""
print("foo")

if True: 
    raise ExecInterrupt

print("bar")
""")
print('This should still be executed')

If your worry is readability, functions are your first line of defense.
