List of far points of two list

[antoniomancera]

I'm trying to create a program that for two list xs and ys, return a list zs with only the element of ys that their distance of any element of xs be at least d.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

def distance(a,b):     y=sqrt((a.real-b.real)**2+(a.imag-b.imag)**2)     return y             def dist(xs,ys,d):     zs=[]     for i in range(0,len(xs)-1):         for k in range(0,len(ys)-1):             if distancia(xs[i],ys[k])<=d:                 zs=zs                 break             else:                 zs=zs+[ys[i]]     return zs

But it's wrong, and I don't know how to fixed it. Could you help me please?.

Thank you.

But it's wrong,

Is not helpful, if you are getting an error, post the error code in it's entirety. What output are you getting versus what you expect.  Include a small sample of 'xs', 'ys' and 'd'.

Python strongly encourages the use of descriptive variables, so stop using meaningless single and short variable names.

I'm sorry, I wanted to say that the output aren't that I expected. Because for example if I input xs=[1,2], ys=[3,4,5], and d=0.5. The output it's

1 2	dist([1,2],[3,4,5],1) Out[7]: [3, 3]

. However, if the program was well wrote should output [4,5].
I have created this new program

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

def distance(a,b):     y=sqrt((a.real-b.real)**2+(a.imag-b.imag)**2)     return y   def distancelist(list1,a):     y=[]     for i in range(0,len(list1)):         y=y+[distance(list1[i],a)]     return y                       def countthefarpoint(list1,a,dis):     y=distancelist(list1,a)     cont=0     for i in range(0,len(y)-1):         if y[i]>dist:             cont=cont+1         else:             cont=cont     return cont

The program distance(a,b) output the distance between a and b. The program distancelist output a list with the distnace between a and each element of list1, for example for a=2 lis1=[2,3,4,7,-1j] the ouput it's

1 2	distancelist([2,3,4,7,-1j],2) Out[10]: [0.0, 1.0, 2.0, 5.0, 2.2360679774997898]

. And the program countthefarpoint take a list "list" a number "a" and a distance "dist", and output how many times the distance between "a" and each element of "list1" it's bigger than "dist". For a=2 list1=[2,3,4,7,-1j], and dist=2, should output 3, but the output it's

1 2	countthefarpoint([2,3,4,7,-1j],2,1) Out[12]: 0

. I have created the program countthefarpoint, beacause I want to create a program which for two list, lis1 and list2,and a distance dist. Output list1, and the elements of list2 which their distance of each element of list1 be at least dist.
