Assertion (A). To use the Pandas library in a Python program, one must import it.
Reasoning (R). The only alias name that can be used with the Pandas library is pd.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.
- A is true but R is false.
- A is false but R is true.
Answer
A is true but R is false.
Explanation
In order to work with Pandas in Python, we need to import the Pandas library into our Python environment using the statement import pandas as pd. While pd is a common alias used with the Pandas library, it's not the only alias that can be used. We can import Pandas using other alias names as well.
