Importance

Redundant imports can cause a performance degrade and make code harder to understand when reading through it. Also it causes unneeded dependencies within your modules. In most programming languages, unused imports may have side effects and that may be a common false positive. However those should be avoided.

How to fix this

Usually, unused imports can simply be removed.
