I'm trying to store or arrange three sets of two-dimensional data into three 2xN matrices that are stored as NumPy arrays.

```
1. import os # for file handling functions
2. import numpy as np # for array/matrix processing
3. import matplotlib.pyplot as plt # for general plotting
4. from mpl_toolkits.mplot3d import axes3d # for 3d plotting
5.
6. wordList=[]
7. numFiles = 0
8. numDataSets = numVectors = sizeVector = 0
9.
10. print"\n\nBeginning data processing."
11. # traverse filePath folder
12. filePath = "Train"
13. for file in os.listdir(filePath):
14. numDataSets +=1 # one data set per file
15. print "Loading the file: " + file + "."
16. tempFile = open(filePath+"/"+file, 'rU')
17. for line in tempFile:
18. numVectors +=1 # one vector per line
19. for word in line.split():
20. sizeVector +=1 # components in vector
21. wordList.append(word)
22.
23. sizeVector = sizeVector / numVectors
24. numVectors = numVectors / numDataSets
25.
26. # print"\nHere's all the data:\n", wordList, "\n\n"
27. print "numDataSets: ",numDataSets
28. print "numVectors: ",numVectors
29. print "sizeVector: ",sizeVector
30. x = eval(wordList[5])
31.
32. # Structure our arrays to hold our data.
33. # We'll use the three sample class data sets from the text.
34. # sizeVector of rows and numVectors of columns for column vector data.
35. # In other words, each feature vector will be a column vector for set array.
36. w1 = np.zeros((sizeVector, numVectors))
37. w2 = np.zeros((sizeVector, numVectors))
38. w3 = np.zeros((sizeVector, numVectors))
39.
40. # Load matrix array with class w1 numeric values,
41. # replacing elements indexed as in matrices row, col starting from 0.
42. # Pull elements from wordList based on dataSet, sizeVector, and
43. # which vector we're on during the column, row iteration.
44.
45. skip = numVectors*sizeVector
46.
47. dataSet = 0
48. for j in range(sizeVector):
49. for i in range(numVectors):
50. (do something - nothing I've tried is working)
51. print "\nClass w1 is as follows: \n",w1
52.
53. dataSet = 1
54. for j in range(sizeVector):
55. for i in range(numVectors):
56. (do something - nothing I've tried is working)
57. print "\nClass w2 is as follows: \n",w2
58.
59. dataSet = 2
60. for j in range(sizeVector):
61. for i in range(numVectors):
62. (do something - nothing I've tried is working)
63. print "\nClass w3 is as follows: \n",w3
```

I need advice on how to get my dataSet(s) set up in this 2xN format.
