Speed up for loop

[icbruzzler]

Hello,
is there an alternative method to get the following code snippet faster?

var_refp.size contains 60001 elements, ground freq can change and is something between 200 and 400
That code is in an iteration loop and is executed about 10-50 times

 for k in range(0, var_refp.size, 1):
            if math.fmod(k, ground_frequenz) == 0:
                var_cur_ref = var_refp[k]
            var_refp[k] = var_cur_ref

Tank you

k is a value from range(), and is thus an int.  If ground_frequenz is also an int (as suggested by your post), then you could use the modulus operator instead of math.fmod, which could be faster.  ie:

for k in range(var_refp):
    if k % ground_frequenz == 0:
        # etc

But you should probably just profile it, to see if this is actually the slow part of what you're doing.

As it appears from the @nilamo's post there is no need to set start=0 and step=1 for the range() function. These are the default values.
