Converting C style for loop to python

Question

How do you convert a c-style for loop into python?

for (int i = m; i >= lowest; i--)

The best that I came up with was:

i = mid
for i in range(i, low,-1):

Answer 1

for i in range(m, low - 1, -1):

Keep in mind range is exclusive of the stop parameter.

range(...)
    range(stop) -> list of integers
    range(start, stop[, step]) -> list of integers

The difference between this code and the C code is that in Python 2, a list is being constructed in memory by range so for very huge ranges this could be a problem. Replacing range with xrange would not build a list in memory and make the code practically the same. In Python 3 this issue no longer exists.
