Make a new variable, np_weight_lb, containing the entire second column of np_baseball.

To create a new variable called np_weight_lb that contains the entire second column of an existing variable np_baseball, follow these steps:

1. Break Down the Problem

We need to:

1. Access the second column of the np_baseball array.
2. Store that column in a new variable named np_weight_lb.

2. Relevant Concepts

• NumPy indexing: In Python's NumPy library, you can access elements of an array using indices.
• The second column can be accessed using the index [ :, 1 ], since indexing in Python starts at 0.

3. Analysis and Detail

1. If np_baseball is a NumPy array, the second column can be accessed through slicing.
2. We will create the new variable and assign the sliced array to it.

4. Verify and Summarize

After executing the command, np_weight_lb should now contain all the weights from the second column of the np_baseball variable.

Final Answer

np_weight_lb = np_baseball[:, 1]

This code will successfully create the variable np_weight_lb, which now holds all the values from the second column of the np_baseball array.
