Answer / Durga Rani
In Perl, a my variable is a lexical (or local) variable with a scope limited to the current block. It is created when first used within that block and destroyed when the block ends. On the other hand, a local variable has a broader scope: it is visible in the entire enclosing subroutine. The main difference between my and local variables is their lifetime and visibility: my variables are created and destroyed based on blocks, while local variables exist for the duration of the subroutine.
