[Numpy-discussion] printing array in tabular form

[Sudheer Joseph]

Thank you Derek,
                   However I get below error. Please tell me if any thing I am missing.

file "read_reg_grd.py", line 22, in <module>
    np.savetxt("file.txt", IL.reshape(-1,5), fmt='%5d', delimiter=',')
AttributeError: 'list' object has no attribute 'reshape'

with best regards,
Sudheer
