What does the power operator (**) in Python translate into?
网页2022年1月12日 · 1. The ** operator will, internally, use an iterative function (same semantics as built-in pow() (Python docs), which likely means it just calls that function anyway). Therefore, if you know the power and can hardcode it, using 2*2*2 would likely be a little faster than 2**3. This has a little to do with the function, but I believe the main ...
