smallest Cosine distance in Graph

[vino689]

my problem is to list the smallest Cosine distance in Graph
S= [(1,2),(3,4),(-1,1),(6,-7),(0, 6),(-5,-8),(-1,-1),(6,0),(1,-1)] # these are the list of x & y axix
P= (3,-4) # so here i have to find the distance between each tuple in S with P & find the top 5 lowest distance axis

below is the code i have written to find the cosine distance between each Tuple in S & P .


import math
import numpy as np
from sklearn.metrics.pairwise import cosine_similarity

S= [(1,2),(3,4),(-1,1),(6,-7),(0, 6),(-5,-8),(-1,-1),(6,0),(1,-1)]
for i in range (0,len(S)):
#print(S[i])
#print(np.ndim(S[i]))
J=np.reshape(S[i],(1,2))
#print(J)
#print(np.ndim(J))
P=[(3,-4)]
#print(np.ndim(P))
A=cosine_similarity(J,P)
#print(A)
C=1-A # Cosine Distance = 1-cosine similarity
#print©
#print(np.ndim©)
D=np.reshape(C,(1))
#print(np.ndim(D))
print(D)

# if i print D , i am getting the below Cosine distance
[1.4472136]
[1.28]
[1.98994949]
[0.00211989]
[1.8]
[0.63960072]
[0.85857864]
[0.4]
[0.01005051]
now i want to Sort 5 distance in ascending order (Less distance) & to print the respective X & Y axis

Im new here so maybe I don't know but it looks like you are missing your tab spacing. Maybe try posting the code in code tags to preserve tab spacing. Do that first before I try to guess what is part of the for loop and what is after the for loop.

I tried but its not getting indented , FYI.. in the Code all the lines are indented after for loop

you need two dimensions so that you can store data about your data and it will remain correlated even after a sort.

I never learned a way to do S[][].sort with two dimensional arrays so the only way I know with a built in function is sorted()
if it breaks because of the two dimensional array I would just write a sort function from scratch that is orthogonal to my two dimensional array. I hope this helps get you in the right direction. sorry I don't have all the answers. I am a first year student.
