In Seaborn, which function is used to create a scatter plot with the possibility of several semantic groupings?
- sns.boxplot()
- sns.lineplot()
- sns.pairplot()
- sns.scatterplot()
In Seaborn, the sns.scatterplot() function is used to create scatter plots with the possibility of several semantic groupings. It allows you to color and style the points based on additional variables, making it useful for exploring relationships in complex datasets.

In Python, the ____ statement can be used to assert that a certain expression is true, typically used for debugging purposes.
- assert
- debug
- validate
- verify
The assert statement in Python is used to check whether a given expression is true. If the expression is false, it raises an AssertionError exception, which is helpful for debugging and ensuring that assumptions in your code hold true.
In Python, the ____ statement is used to interrupt loop iteration and jump to the next iteration of the loop.
- break
- continue
- pass
- return
In Python, the 'break' statement is used to interrupt loop iteration and exit the loop prematurely. When 'break' is encountered inside a loop, it jumps to the next statement after the loop.
