Red underlined wavy lines and red exclamation marks appear in Eclipse

I have been using eclipse to write Python, but I always see red wavy lines in some strings,

It feels uncomfortable to look at. After working on it for a long time, I finally eliminated it. It turned out to be spell check

Windows->Preferences->General->Editors->Text Editors->Spelling Just cancel Enable spell checking.

There is also a prompt that a yellow exclamation mark appears

Window>>Preferences>>General>>Editors>>Text Editors>>Annotations
Select Warnings on the right and remove all the ticks next to it..
