Technical differences in doing nothing vs. pass ""

I have learned that to do nothing in python, one may use the pass keyword:

if True:
    pass

However, when I do this:

if True:
    ""

I seemingly get the exact same result. Nothing happens.

What exactly happens when I call pass vs. when I call ""? Is one minusculely faster or more efficient?

Usually we use the `Ellipsis` object rather than an (interned) empty string, but the net effect is the same. – Mad Physicist May 08 '20 at 05:43
