Consider this program def foo(a,b): return min(zip(a,b)[2]) print foo(range(5), (0,9,-9)) With the default options, 2to3 rewrites this as def foo(a,b): return min(zip(a,b)[2]) print(foo(list(range(5)), (0,9,-9))) For some reason, 2to3 fails to wrap the call to zip in a list, even though the 2to3 documentation says that there is a fixer which does this. Obviously, the generated code will not work in Python 3 since you can't subscript an iterator. |

This is a duplicate of issue 20742. |

Already closed, but FWIW, I think this was incorrectly marked as a duplicate. Issue 20742 discusses a different issue related to lib2to3 and zip. Meanwhile, this issue has been raised again in 28837, so I will continue the discussion there. (I have a patch.) |
