Encode python string directly into bytearray?

In Python, you can do:

b = bytearray(100)
b[0:3] = 'one'.encode()
b[17:20] = 'two'.encode()

This, however, creates an intermediate bytes() object, which is leading to suboptimal performance.

Is there anything like encode_into() that will encode a string directly into a bytearray?

I assume you're working in python3.x, otherwise b[0:3] = 'one' works just fine.

For python3.x, you can use the b string prefix:

b[0:3] = b'one'  # parser creates a bytes object, not a string.
