title: Python read txt file and create array list
body: <p>I have a txt file that I read line by line with my python code:</p>
  
  <pre><code>a = open("data.txt","r")
  inputF = a.readlines()
  for line in inputF:
     print(line)
  </code></pre>
  
  <p>my txt file is this:</p>
  
  <pre><code>Data: 7_8_2014

  </code></pre>
  
  <p>i would like to read this file txt and create a list array as this:</p>
  
  <pre><code>coordsList = [[Road, 488597.653655, 4134910.76248], 
            [Road, 488813.848952, 4134609.01192],
            [Road, 488904.303214, 4134480.54842],
            [Road, 488938.462756, 4134422.3471],
            [Street, 496198.193041, 4134565.19994],
            [Street, 496312.413827, 4134568.14182],
            [Street, 496433.652036, 4134568.08923],
            [Street, 496559.933558, 4134547.91561],
            [Street, 496782.196397, 4134527.70636],
            [Street, 496923.636101, 4134512.56252]]
  </code></pre>
  
  <p>for each tag "Name" into txt file.</p>
  
  <p>With your (Anton vBR) help i have update my code in this way:</p>
  
  <pre><code>import arcpy
  import os, sys
  import io
  
  with open('C:/Users/fdivito/Desktop/FinalProjectData/7_8_2014.txt', 'r') as content_file:
  content = content_file.read()
  i=0
  output = []
  
  
  for row in io.StringIO(content).readlines()[1:]: # skips first row
  if row.startswith("Name"):
      #i = row.split(":")[1].strip()
      i+=1
  else:
      output.append([i]+[float(item.strip()) for item in row.split(",")])
  
  print(output)
  </code></pre>
  
  <p>but i have this error:
  for row in io.StringIO(content).readlines()[1:]: # skips first row
  TypeError: initial_value must be unicode or None, not str</p>
