Print out numbers of increasing distance from center value in Python
$begingroup$
I am trying to print out numbers by increasing positive and negative values around a center number, and I don't think I've found the best way. For example, say I want to find what number in a list my center value is closest to. I do that by adding one, see if it matches, then subtracting one from the original number and see if that matches, then add two from the original number and so on. I know there are other ways of finding the closest match but I'm not looking for that - I'm looking for the best way to print out numbers steadily getting farther from a center value. Here's my code:
def inc_val(center, i, neg_toggle):
mult = 1
if neg_toggle:
neg_toggle = False
mult = -1
else:
neg_toggle = True
mult = 1
i += 1
val = center + (i * mult)
return val, i, neg_toggle
i = 0
center = 24
val = center
neg_toggle = False
my_set = {30, 50, 90}
while val not in my_set:
print(val)
val, i, neg_toggle = inc_val(center, i, neg_toggle)
This prints out the following list, as desired:
24
25
23
26
22
27
21
28
20
29
19
To be clear, I'm interested in the incrementing numbers. The while not in my_set part is just to illustrate. I am not intentionally trying to re-invent anything, so if there's a built-in or simpler way to do this, please let me know.
