Question

What are the two methods used to sort a DataFrame in pandas?

1) sort_index() and sort_values()
2) sort() and sort_values()
3) sort_index() and sort()
4) sort() and sort_index()

Answer 1

The two methods used to sort a DataFrame in pandas are sort_index() and sort_values(), used for sorting by index labels and column values, respectively.

Step-by-step explanation:

The two methods used to sort a DataFrame in pandas are sort_index() and sort_values(). The sort_index() method is used to sort the DataFrame based on the labels along a given axis, which can be the index or column names. In contrast, the sort_values() method is used to sort the DataFrame based on the values in one or more columns.

Both methods provide parameters to specify whether the sorting should be in ascending or descending order, and whether to sort in place or to return a sorted copy of the DataFrame.

The two methods used to sort a DataFrame in pandas are sort_index() and sort_values(). The sort_index() method sorts the DataFrame based on the row index, while the sort_values() method sorts the DataFrame based on the values in one or more columns.
