How do I create a new text file after every loop in a while loop? | 39,545,549 | <p>I have a piece of text which I want to write in different text files, so I'm using a while loop to create a new txt file after every loop.

Or best would be not to create multiple files. Just write into one file and create (no_of_copies-1) symlinks with different names. This would be efficient. </p>

Neural net techniques are very susceptible of scale difference between different feature so standardization of data [mean =0 std =1] for all columns is a good practice. </p>
