How to search range with intervals in Python

I've been given a project and although I've managed to get it to work, part of it looks very messy and I can't think of what I'm sure is a simple fix to it. My knowledge of programming is minimal so most Google searches for it have confused me and I don't really know how to define what I want. Anyone here is the code:

(if x in range(25,76) or x in range(125,176) or x in range(225,276) or
    x in range(325,376) or x in range(425,476) or x in range(525,576) or
    x in range(625,676) or x in range(725,776)):

I think you can see what I'm trying to do but I've had to list it as separate ranges each time, help will be much appreciated!

One option for shortening a lot of ors is to use any, something like:

if any(x in range(start, end) for start, end in [(25, 76), (125, 176), ...]):

or just use arithmetic, if the values will always be integers:

if any(start <= x < end ...):

Alternatively, as you seem to have a regular pattern of ranges (i.e. between 25 and 76 in every hundred), you could use modulo (%) to strip away the hundreds:

if x % 100 in range(25, 76):

and add in x < 776 if that's a fixed upper limit
