Return all values from range() function and add them into an array


I’m trying to make a program which extracts specific PDF pages from a PDF file. To do this, I have an array where I put all page numbers I want to extract. However, to spare myself some time, I want to be able to add all pages between two page numbers (between 1 and 8 for instance).

Currently I have the following code:

def r(n1, n2):
    return range(n1, n2)

if __name__ == '__main__':
    pages_to_keep = [1, 2, 10, r(12,14)]
    print pages_to_keep

The output is:

[1, 2, 10, [12, 13]]

but what I want is:

[1, 2, 10, 12, 13, 14]

The thought here is that the r function can be called in the array to easily add multiple pages, but I want to get rid of the brackets which gets returned from the function. Is there a way to do this?


There are two methods of doing so:

  1. pages_to_keep = [1, 2, 10]+list(r(12,14))
pages_to_keep = [1, 2, 10]
