sort_values(): Use sort_values() when you want to reorder rows based on column values; use sort_index() when you want to reorder rows based on the row labels (the DataFrame’s index). We have many other useful pandas tutorials so you can keep learning, including The ultimate Guide to...
sort_values() You can use the pandas dataframe sort_values() function to sort a dataframe. sort_values(by, axis=0, ascending=True,na_position='first', kind='quicksort') The sort_values() method, a cornerstone of DataFrame sorting, imparts remarkable flexibility, permitting users to custom...
Moreover, once your data are in the DataFrame structure and the data are “clean,” you’ll still need to use some “data manipulation” techniques to analyze your data. Here, I’m talking about things like subsetting, grouping, and aggregating. Pandas has tools for performing all of these...
