From the documentation:
range([start], stop[, step])
The start defaults to 0, the step can be whatever you want, except 0 and stop is your upper bound, it is not the number of iterations. So declare n to be whatever your upper bound is correctly and you will not have to add 1 to it.
e.g.
>>> for i in range(1, 7, 1): print(i)
...

>>> for i in range(1, 7, 2): print(i)

A nice feature, is that it works in reverse as well.

r/learnpython on Reddit: How do you start a for loop at 1 instead of 0?
November 13, 2015 -
I am pulling data from a dictionary and appending it to a list, but it appears that dictionary keys start at 1, not 0.
We have been taught to use for loops for this kind of task, but they initialize at 0. Can I start at 1? If not, what is an alternative? Thanks!
for i in range(len(dict)):

Hi! I'm working on a bot to reply with suggestions for common python problems. This might not be very helpful to fix your underlying issue, but here's what I noticed about your submission: You are looping over an object using something like for x in range(len(items)): foo(item[x]) This is simpler and less error prone written as for item in items: foo(item) If you DO need the indexes of the items, use the enumerate function like for idx, item in enumerate(items): foo(idx, item)

You could also do this, I think: for i in range(1, 10): print i But the bot has the better options. You could also iterate the keys: for key in dict.keys():

range(1, n+1) is not considered duplication, but I can see that this might become a hassle if you were going to change 1 to another number.
This removes the duplication using a generator:
for _ in (number+1 for number in range(5)):

That is, 0 through 99. However, in this special case, you add the loop variable i to the sum, so you could start at 1. But don’t!. Sometime later you’ll modify or copy the code where do want to loop 100 times.

The for index in range(len(list)) loop executes the loop body with index first set to 0, then 1, then 2, etc. up to len(list) - 1. The previous value of index is ignored and overwritten. If you want index to start at iteration + 1, use the 2-argument form of range:
for index in range(iteration + 1, len(list)):

You really should be using enumerate for stuff like this, as you can loop through the index and the value at the same time (which will save you the hassle of using two for-loops).
for i, j in enumerate(list):
print i, j
Your inner loop is overriding the variable index that you defined in the first loop.
