A data analyst is working in a Jupyter notebook and needs to use the `numpy` library. They have already installed it, but when they run `import numpy`, they get a `ModuleNotFoundError`. Which of the following is the most likely cause?

The package was installed in a different Python environment than the one running the notebook.

The package name is misspelled; it should be `numPy`.

The package is not compatible with the operating system.

The package needs to be imported with `from numpy import *` instead.

Which strategy helps make a script robust against unexpected user input?

Use global variables to store all input values

Use the `pass` statement in every except block

Ignore any exceptions that occur

Wrap input parsing in a try-except block to catch ValueError

What is the purpose of a try-except block in Python?

To import modules conditionally

To catch and handle exceptions that occur in the try block

To declare variables that can be used globally

To speed up the execution of code
