surrounded by ve surrounded with arasındaki fark nedir?Sadece örnek cümleler vermekten çekinmeyin.

Most of the time, you can use them interchangeably. I personally prefer to use "surrounded by" more often than "surrounded with"

-

"surrounded with" is better for when things are spread over a large area;
"This neighborhood is surrounded with Christmas lights"

If it's aggressive in any way, "surrounded by" is better;
"I'm surrounded by police cars"
"I'm surrounded by bees"

Here's an example of how 'with' and 'by' can change the meaning when there's aggression:
"I'm surrounded by people who want to kidnap me"
They're looking at me and trying to figure out how to grab me.
"I'm surrounded with people who want to kidnap me"
They don't notice me yet, but they're all around me.

When talking about non-aggressive people, there's no difference in meaning:
"I'm surrounded with/by people"
"I'm surrounded with/by good people"
"I'm surrounded with/by bad people"
"I'm surrounded with/by people who want to hug me"
