how to write a C-style for loop?

[John Salerno]

I assume this is the way for loops are written in C, but if it helps to 
be specific, I'm referring to C# for loops. The Python for loop seems to 
be the same (or similar) to C#'s foreach loop:

foreach int i in X

But how would you write a C# for loop in Python? Do you rework a while 
loop, or use the range() function?

Here's an example:

for (int i = 0; i < 50; i += 5)

How would that go in Python, in the simplest and most efficient way?

Thanks.
