Read the article again. He says Python is unityped. The word "type" in mathematics and computer science has a meaning which is not the same as your usage of the word. Well-typed programs should not go wrong. Python programs can crash at runtime due to simple type errors (expected integer but got a string). A crash is a crash, from a theoretical point of view it matters not that the error is prettier than a segmentation fault. Python is not strongly typed, it just has good error messages.
