I'm having a weird problem with the following piece of code.
from math import sqrt
def Permute(array):
result1 = []
result2 = []
if len(array) <= 1:
return array
for subarray in Permute(array[1:]):
for i in range(len(array)):
temp1 = subarray[:i]+array[0]+subarray[i:]
temp2 = [0]
for num in range(len(array)-1):
temp2[0] += (sqrt(pow((temp1[num+1][1][0]-temp1[num][1][0]),2) + pow((temp1[num+1][1][1]-temp1[num][1][1]),2)))
result1.append(temp1+temp2)
return result1
a = [['A',[50,1]]]
b = [['B',[1,1]]]
c = [['C',[100,1]]]
array = [a,b,c]
result1 = Permute(array)
for i in range(len(result1)):
print (result1[i])
print (len(result1))
What it does is find all the permutations of the points abc and then returns them along with the sum of the distances between each ordered point. It does this; however, it also seems to report a strange additional value, 99. I figure that the 99 is coming from the computation of the distance between point a and c but I don't understand why it is appearing in the final output as it does.
