Did it myself vs. Did it by myself

[jupiter]

Hello teachers,

Please see the following:

Q: Who did this homework?

A1: I did it myself.
A2: I did it by myself.

What is the difference between A1 and A2?

Thanks in advance

Jupiter

Sorry, I had to change my answer. Initially I didn't pay enough attention to your specific example.

Usually both answers would be taken to mean the same thing, which is "I did all of it alone; no one helped me." However, they can have different meanings.

"I did it by myself." should only carry the above meaning.
''I did it myself." can also mean "No one did it for me; I actually did it."

Both of them are probably the same.
