Python for 2 ranges

I want one long list, say [1,2,3,4,5,15,16,17,18,19] as an example. Try this for Python 2.x: range(1,6) + range(15,20). Or if you.re using Python3.x. Can be done using list-comprehension. >>> [i for j in (range(10), range(15, 20)) for i in j] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 15, 16, 17, 18, 19]. Works for. 20 Aug 2013 The range() function works a little bit differently between Python 2.x and 3.x under the hood, however the concept is the same. We.ll get to that a.

Seq = L[start:stop:step] seq = L[:2] # get every other item, starting with the first seq = L[1:2] # get every other item If you need only the index, use range and len. This is why Python has a special function called range. range() takes two numbers and tells Python to count from the one to the other. By default, it does this in.

I was wondering what the best method was in Python programming for 2 discontinued ranges. e.g. I want to use the range 3 to 7 and 17 to 23. 362 Using the range function. Often we want to do something a large number of times, in which case typing all the numbers becomes tedious. The range().

Python list initialization using multiple range statements -

Range(10) [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] range(n) generates the progression of integer numbers starting with 1 and ending with (n -1) range() can also be called with. In Python versions before 3, range() creates a list, as you say. In Python 3, it creates a generator. Effectively, what they did going from 2 -> 3.

The Pygame games make use of Python 2 because the Pygame library is not yet In Python 2, the range() function returns an actual list with the integers. [Edit]. The Shafrir-2 was credited with 89 kills in the 1973 Yom Kippur War. During its whole service life, it is credited with a total of 106.

Indicate input to Python (these are the default prompts of the interactive interpreter). Everything else is noprimes = [j for i in range(2, 8) for j in range(i*2, 50 i)].
