title: Benford's law program
body: <p>I have to write a program that proves Benford's Law for two Data lists. I think I have the code down for the most part but I think there are small errors that I am missing. I am sorry if this is not how the site is supposed to be used but I really need help. Here is my code.</p>
  
  <pre><code>def getData(fileName):
  
      data = []
      f = open(fileName,'r')
      for line in f:
          data.append(line)
      f.close()
  
      return data
  
  def getLeadDigitCounts(data):
  
      counts = [0,0,0,0,0,0,0,0,0]
  
      for i in data:
          pop = i[1]
          digits = pop[0]
          int(digits)
          counts[digits-1] += 1
  
      return counts
  
  def showResults(counts):
  
      percentage = 0
      Sum = 0
      num = 0
      Total = 0
  
      for i in counts:
          Total += i
  
      print"number of data points:",Sum
      print
      print"digit number percentage"
      for i in counts:
          Sum += i
          percentage = counts[i]/float(Sum)
          num = counts[i]
          print"5%d 6%d %f"%(i,num,percentage)
  
  
  def showLeadingDigits(digit,data):
  
      print"Showing data with a leading",digit
      for i in data:
          if digit == i[i][1]:
              print i
  
  def processFile(name):
  
      data = getData(name)
      counts = getLeadDigitCounts(data)
      showResults(counts)
  
      digit = input('Enter leading digit: ')
      showLeadingDigits(digit, data)
  
  def main():
  
      processFile('TexasCountyPop2010.txt')
      processFile('MilesofTexasRoad.txt')
  
  main()

  <p>Again sorry if this is not how I am supposed to use this site. Also, I can only use programming techniques that the professor has showed us so if you could just give me advice to clean up the code as it is I would really appreciate it.</p>
  
  <p>Also, here are a few lines from my data.</p>
  
  <pre><code>Anderson County     58458
  Andrews County  14786
  Angelina County     86771
  Aransas County  23158
  Archer County   9054
  Armstrong County    1901
