According to me understanding, A should be faster as characters would
shortcut this 1-byte string ‘h’ without malloc;
It sounds like you're expecting characters to be stored
"unboxed" like in Java.
That's not the way Python works. Objects are used

Hi,
There are 2 statements:
A: a = ‘h’
B: b = ‘hh’
According to me understanding, A should be faster as characters would shortcut
