Question

Is this the correct way to declare and iterate through an array in Python, where each element is multiplied by a constant value?

timeArray = array([0]*1000)

for x in timeArray:
    timeArray[x] = x * deltaTime
    print(timeArray)

Answer 1

timeArray = [i*deltaTime for i in range(1000)]

will construct a list with the contents that you want. Indexing into a list takes O(1) time, the same as for an array. Python lists are very fast, they’re actually implemented as arrays.

Are you sure you want to print the contents of the array/list while it’s being constructed?

(Aside: If you want faster arrays because you’re doing number crunching, then a Numpy array might be a better choice:

timeArray = numpy.arange(1000)
timeArray *= deltaTime
