long list of numbers

I want to write a long list of numbers in python, but I don't want to enter the numbers one by one because that's boring. So, how can I do that? For the ones who are familiar with MATLAB, I want to write something witch looks 1:100, but I don't know how to write it in python! By the way, I can append numbers for a one-element-list in a loop but I am looking for something mostly like a built in operator.

Do you want something like the builtin range function?

>>> range(1,10)
[1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> range(1,10,2)
[1, 3, 5, 7, 9]

in python 3.x, range doesn't return a list anymore, it returns a range object. Range objects behave like lists in a lot of ways, but they aren't actually lists. If you really need a list on python 3.x, you can use list(range(...))

Numpy has a similar function arange which will work with floats as well:

>>> np.arange(1,2,.1)
array([ 1. ,  1.1,  1.2,  1.3,  1.4,  1.5,  1.6,  1.7,  1.8,  1.9])
