# Intervals in Python3

Hi! Could someone teach me how to create an interval in Python? I've already searched on the internet but came without a good answer. I get an error whenever I type ---> x=interval ( [2,y-1] ). I need integers to build my very first program. I tried to import interval from interval module but Py doesn't recognize it. Thanks in advance!

Virgil Baclanov Let's say you want to divide the integer 294 by every integer in the interval from 13 up to 54. The results can make a list like this: x = 294 results = [x/y for y in range(13, 55)] Observation: the `%` symbol is for modulus operation, not for division.

Assume you need an interval from 1 to 9. So you do: my_interval = list(range(1, 10)) # the end of the interval is non-inclusive # so if you need an interval from "m" up to "n", you should do range(m, n+1)

You would do something like this: new_list = [] for i in interval: new_list.append(i % 5) print(new_list) -------------- To shorten that you could do: print([i % 5 for i in interval])

You might be looking for range objects: >>> x = range(50, 100) >>> len(x) 50 >>> 83 in x True >>> x[3] 53 >>> x[-1] 99 >>> x[13:24] range(63, 74) >>> for i in range(11): print(i*i, end = ' ') 0 1 4 9 16 25 36 49 64 81 100

Eduardo Petry thanks! But, what do I do when I wanna divide an integer by *each* integers in the interval? example -- I type ---> if dividend%interval==0: ... but Phyton is telling me that it is an unsupported operand type(s) for %: 'int' and 'list'
