It is assumed that each column contains a physical quantity. If the columns are separated by whitespace.
When a mixture of number strings and character strings
for line in open('test.tab', 'r'):

>>> import numpy as np
>>> data=np.loadtxt('input.txt').T
When a mixture of number strings and character strings
f=open('output.txt','w')
f.write(moji+'\n')
f.close()
>>> np.savetxt('output.txt',data.T)
