Suppose you have the following modules: -foo.py:: +:file:`foo.py`:: from bar import bar_var foo_var = 1 -bar.py:: +:file:`bar.py`:: from foo import foo_var bar_var = 2 The problem is that the interpreter will perform the following steps: -* main imports foo -* Empty globals for foo are created -* foo is compiled and starts executing -* foo imports bar -* Empty globals for bar are created -* bar is compiled and starts executing -* bar imports foo (which is a no-op since there already is a module named foo) -* bar.foo_var = foo.foo_var +* main imports ``foo`` +* Empty globals for ``foo`` are created +* ``foo`` is compiled and starts executing +* ``foo`` imports ``bar`` +* Empty globals for ``bar`` are created +* ``bar`` is compiled and starts executing +* ``bar`` imports ``foo`` (which is a no-op since there already is a module named ``foo``) +* The import mechanism tries to read ``foo_var`` from ``foo`` globals, to set ``bar.foo_var = foo.foo_var`` The last step fails, because Python isn't done with interpreting ``foo`` yet and the global symbol dictionary for ``foo`` is still empty. |
