Question
Q.18 Which of the following is correct Features of DataFrame?1. Potentially columns are of different types2. Can Perform Arithmetic operations on rows and columns3. Labelled axes (rows and columns)4. All of the above
Solution
The correct answer is 4. All of the above.
Here's why:
-
Potentially columns are of different types: This is true. In a DataFrame, each column can have its own data type, which is very useful when dealing with real-world data.
-
Can Perform Arithmetic operations on rows and columns: This is also true. Pandas provides a wide range of mathematical functions that can be applied on rows and columns.
-
Labelled axes (rows and columns): This is one of the key features of DataFrame. Each row and column can have a label, which makes data manipulation easier.
So, all of the statements are features of a DataFrame.
