Describe Data Operations in Pandas?

Answer

In Pandas, there are different useful data operations for DataFrame, which are as follows:

• Row and column selection

We can select any row and column of the DataFrame by passing the name of the rows and columns. When you select it from the DataFrame, it becomes one-dimensional and considered as Series.

• Filter Data
   

We can filter the data by providing some of the boolean expressions in DataFrame.

• Null values

A Null value occurs when no data is provided to the items. The various columns may contain no values, which are usually represented as NaN.
