No, Gabriel is correct. range(n) creates a list of integers starting at 0 and going to n-1 (inclusive), not n. In [1]: range(9) Out[1]: [0, 1, 2, 3, 4, 5, 6, 7, 8] In [2]: len(range(9)) Out[2]: 9 In [3]: len(range(1, 9)) Out[3]: 8 In [4]: range(10) Out[4]: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] In [5]: len(range(10)) Out[5]: 10 > On Feb 3, 2008 4:38 AM, Gabriel Genellina <[EMAIL PROTECTED] > <mailto:[EMAIL PROTECTED]>> wrote: > > En Sun, 03 Feb 2008 01:03:43 -0200, James Matthews > <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]>> > escribió: > > Sorry to be nitpicking, but people coming from other languages may get > confused by the wrong examples: > > > What i do is a simple range call. for i in range(number of times > i want > > to repeat something) > > I guess it comes from my C days for(i=0;i<100;i++) { or in python > for i > > in range(99): > > Should be `for i in range(100)` to match exactly the C loop.
