Matrices and printing problems

Question

So this code is suppose to display an "*" if the terrain number is less than or equal to the flood level number. If it is larger a " " is replaced in the matrix.

The output I am suppose to get looks like this:

100 104 107 103 109 106 112 115
102 101 105 100 106 110 115 120
103 99 102 96 101 105 110 122
 97 94 98 100 104 100 109 113
 94 93 95 98 100 103 108 110
 97 99 101 101 104 108 110 115
 99 101 104 107 110 110 115 125
Flooding at elevation = 95

   *
 * * *


Flooding at elevation = 100
 *
 *
 * *
 * * * * *
 * * * * *
 * *
 *
Flooding at elevation = 105
 * * *
 * * * *
 * * * * * *
 * * * * * *
 * * * * * *
 * * * * *
 * * *

The spacing might be a little off due to transfer issues with the PDF it is on.

My output looks like this:

  100  104  107  103  109  106  112  115
  102  101  105  100  106  110  115  120
  103   99  102   96  101  105  110  122
   97   94   98  100  104  100  109  113
   94   93   95   98  100  103  108  110
   97   99  101  101  104  108  110  115
   99  101  104  107  110  110  115  125

Flood elevation is:  95

As you can see, I am getting way too many asterisks. I know the problem is in one of the loops but I'm just not sure where. I was thinking in my main function. What the output SHOULD be was very messed up in the transfer from PDF text, as you can see at elevation 100 and 105 it was very messed up. 95 is perfect and servers as the best example.

This is my code, any help would be more than appreciated.

def main():
  # Getting terrain from read terrain and flood elevations from flood levels
  data = readTerrain()
  floodElevation = floodLevels()

  # Printing the matrix of terrain numbers
  printTerrain(data)

  # Making the matrix of "*" and " " ready to print
  floodMatrix = floodMap(data, floodElevation)

  # Move through the list of flood elevations and print each map for that number
  for num in floodElevation:
    print()
    print("Flood elevation is: ", num)
    print()
    printFlood(floodMatrix)

# Def readTerrain
# @return returns the matrix of numbers. A list of lists.
def readTerrain():
  inFile = open("terrain.txt", "r")
  data = inFile.readlines()

  matrix = []
  for line in data:
    matrix.append(line.rstrip().split(" "))

  inFile.close()
  return matrix

# Def printTerrain
# @param matrix - gets the matrix from readTerrain and prints the matrix.
# @return returns the printed matrix
def printTerrain(matrix):
  for i in range(len(matrix)):
    for j in range(len(matrix[0])):
      print("%5s" % matrix[i][j], end="")

    print()

  return matrix

# Def floodMap
# @param matrix, passing the data in to compare the numbers.
# @param h2OElevation, passing in the flood levels to compare to the terrain     levels
# @return map, returns the matrix of "*" and " "
def floodMap(matrix, h2OElevation):
  map = []
  for num in h2OElevation:
    for i in range(len(matrix)):
      row = []
      for j in range(len(matrix)):
        if matrix[i][j] <= num:
          row.append("*")
        else:
          row.append(" ")

      map.append(row)

  return map

# Def floodLevels
# @return floodElevation, returns a list of numbers of the h2OElevations
def floodLevels():
  inFile = open("flood.txt", "r")
  elevation = inFile.readlines()

  floodElevation = []
  for line in elevation:
    floodElevation.append(line.rstrip())

  inFile.close()

  return floodElevation

# Def printFlood
# @param floodMatrix, brings the floodMap of "*" and " " to print the matrix
# @return floodMatrix, returns the printed matrix of flooded areas
def printFlood(floodMatrix):
  for i in range(len(floodMatrix)):
    for j in range(len(floodMatrix[0])):
      print("%5s" % floodMatrix[i][j], end="")

    print()

  return floodMatrix


# Call main
main()
