I'm very new to python script and I am attempting to understand a part of a program developed at my work place because the have the most computer knowledge here, though still very little and the person who developed the program is no longer accesible. Here's the problem i'm attempting to solve:
I have a .txt file that I believe is converted to an array by a comma delinated string. there is then a tab delinated string of the first four terms as floats. the program is supposed to compare the values in the array to desired values given by the program and find a value closest to the desired value given in the array based on a user inputed allowed percentage deviation. The program is working properly, however, rather than pulling the closest value to the given desired value from the array it is pulling something else that I am assuming is one of three things.
a. it's pulling the first value that it finds in the interval
b. it's pulling all the values in the interval and then averaging the value
c. it's pulling the first in the interval, the last, and finding the midpoint
what i would like it to do is either find the the exact integer in the deviation that is closest to the given, or pull the highest value in the range, either would work, it's just whichever is easiest.
so here's what the code looks like: (I think this is where the program is sorting this list)
i could not find the value for "ideal" anywhere in the program, and perhaps that is the very problem.
ref is the matrix of ideal values chosen by the user
dev=the allowed deviation percentage entered in float form by user.
def sort(ideal,D,dev): if D > D: if D > D: if D < ideal*dev: return 2 else: return -1 else: if D < ideal*dev: return 1 else: return -1 else: if D < D: if D < ideal*dev: return 0 else: return -1 else: if D < ideal*dev: return 2 else: return -1
I greatly appreciate any help that could be provided!
