When applying an arithmetic operation between a Series and a scalar number, what happens? A) The Series is converted into a scalar. B) The operation is applied to the first entry only. C) The operation results in an error. D) The operation is applied to each entry of the Series.
Understand the Problem
The question is asking about the behavior of applying arithmetic operations between a Series (likely from a programming library such as Pandas) and a scalar number, and it presents multiple choice options regarding the outcome.
Answer
The operation is applied to each entry of the Series.
The operation is applied to each entry of the Series.
Answer for screen readers
The operation is applied to each entry of the Series.
More Information
When performing arithmetic operations in libraries like Pandas, applying a scalar to a Series results in the operation being applied element-wise. This means that the operation is conducted on each element within the Series individually, and the result is a new Series containing the results of these operations.
Tips
A common mistake might be thinking that the operation only affects the first element or leads to an error. However, in vectorized operations, the whole Series is involved.
