Write a function named power that accepts two arguments, a and b and calculates a raised to the power b.

power.py

def power(a,b):
  if b == 0:
      return 1
  else:
    return eval(((str(a)+"*")*b)[:-1])

This should work,for JavaScript

function power(a, b){
var result = 1;

if (b > 0)
{
    for (var i = 1; i <= b; ++i)
    {
        result *= a;
    }
}
else if (b < 0)
{
    for (var i = -1; i >= b; --i)
    {
        result /= a;
    }
}

return result;

}

please could you please explain this code in lem man language, trying to digest the logic
