Python zip/list comprehension explanation

#Python
numbers = [4,5,6,7]
powers = [0,1,2,3]
results = [a**b for a,b in zip(numbers,powers)]

#C
int[] numbers = {4,5,6,7};
int[] powers = {0,1,2,3};
int[] results = new int[numbers.Length];

for (int i = 0; i < numbers.Length; i ++) {
    results[i] = (int)System.Math.Pow(numbers[i], powers[i]);
}

#results = 1, 5, 36, 343
