title: Plotting an array in Python
body: <p>I'm trying to plot a generated array in Python. The array is generated from maze.txt as you can see below. The result is an array composed of only 0's and 1's where each 0 and 1 represents one grid square on the map. The 0's are boundaries, this can be black or any color for that matter, and the 1's are the path that has been navigated. </p>
  
  <p>Searching around I thought that matplotlib could accomplish what I'm trying to do but I'm not quite sure how to implement it. I'm very inexperienced with Python. Thank you for any suggestions/help.</p>
  
  <pre><code>file = open("maze.txt", 'r')
  arr = []
  for line in file.readlines():
      #print();
      arr1 = []
      for c in line:
          if(c.isspace() and (c!="\n")):
              arr1.append(1)
              #print("1",end="")
          elif(c!="\n"):
              arr1.append(0)
              #print("0",end="")
  
      arr.append(arr1)
  #print()
  #print(arr)
  for row in arr:
      print(row)
