How to execute python module?

Question

I want to execute following Python module named JD.py using results.py file and lines.txt. these files are given below:

JD.py

def line_info():
 import fileinput
 import os
 n_1 = []
 for line in fileinput.input(os.path.join(os.path.dirname(__file__),'lines.txt')):
  s_n=0
  n_n=0
  C_1 = list(map(float,line.split( ))) # OR C_1 = [float(x) for x in line.strip().split()]
  X=[]
  Y=[]
  Z=[]
  n_1=[]
  X.append(C_1[0])
  Y.append(C_1[1])
  Z.append(C_1[2])
  s_n += 1
  n_n+=1
  n_1.append([s_n, n_n,C_1[0], C_1[1], C_1[2]])
  return n_1    

results.py

import JD as n_1 
N= n_1.line_info()
print(N)  

**

> lines.txt

**

0.2356 0.7568 0.4389    
0.6356 0.8568 0.5389   
0.9356 0.7568 0.6689   
0.0356 0.8568 0.6389   
0.8356 0.2568 0.7389   
0.8756 0.5568 0.8389  

but it gives first line of the .txt file only. how can I get the remaining lines of the .txt file as results.
