from module import * risks

Question

Accepted Answer

The real danger of `import *` is namespace pollution. If two modules both export a name like `open` or `filter`, the second import silently overwrites the first - and there is no warning. You end up calling a completely different function than you intended, and the bug is nearly invisible because the name still works. Explicit imports (`from module import specific_name`) make the source of every name unambiguous and prevent this class of error entirely.
