Write a Python program to check if a list’s length is divisible by a given number and then break it into equal-sized sets. Write a Python program to implement a function that partitions a list into chunks of a given size and returns a boolean indicating if the partition was perfect. Wr...
Qualitative (or categorical) palettes are best when you want to distinguish discrete chunks of data that do not have an inherent ordering. When importing seaborn, the default color cycle is changed to a set of six colors that evoke the standard matplotlib color cycle while aiming to be a bit...
