Question

Is there some function which will tell me how many bytes does a string occupy in memory?

I need to set a size of a socket buffer in order to transfer the whole string at once.

Answer 1

import sys
sys.getsizeof(s)

# getsizeof(object, default) -> int
# Return the size of object in bytes.

But actually you need to know its represented length, so something like len(s) should be enough.
