Reshape data frame in wide format into a long format There is no shortcut to knowledge; and there are no worthwhile data without preprocessing. In the first three sections of this chapter, we discuss situations that necessitate data preprocessing and how to handle them. In the final sectio.....
We then use the Python “dot” notation to call the method. Inside of the call toreshape(), we need to provide a tuple of values that specify the shape of the new array. Keep in mind that thereshape()method doesn’t operate directly on the original NumPy array. It produces anewarray...
