Why I can call 'print' from 'eval'

Question

For code:

#!/usr/bin/python

src = \"\"\"
print \'!!!\'
import os
\"\"\"

obj = compile(src, \'\', \'exec\')
eval(obj, {\'__builtins__\': False})

Answer 1

The __import__ method is invoked by the import keyword: python.org

If you want to be able to import a module you need to leave the __import__ method in the builtins:

src = """
print '!!!'
import os
"""

obj = compile(src, '', 'exec')
eval(obj, {'__builtins__': {'__import__':__builtins__.__import__}})
