Underneath that, write the corrected sentence without the comma splice.

This is correct:

thank you I also need to put a sentence without the comma splice

Is this correct?
We swam for two days and we were tired.

No. This is a compound sentence with two independent clauses. A comma is needed after "days."

The corrected sentence without the comma splice would be: "We swam for two days, and we were tired."

To solve the comma splice in this sentence, you can use a coordinating conjunction (such as "and") to properly join the two independent clauses. So, by adding a comma before the coordinating conjunction, the sentence becomes grammatically correct without a comma splice.
