In the above post, I have presented some important programming takeaways to know and keep in mind while performing Machine Learning practices to make your implementation faster and effective. Following which we are going to see more of these hacks. Let us begin.

11. Manipulating Wide & Long DataFrames:

The most effective method for converting wide to long data and long to wide data is pandas.melt() and pandas.pivot_table() function respectively. You will not need anything else to manipulate long and wide data into one another other than these functions.
