The ____ attribute in a Matplotlib Axes object represents the y-axis.
- get_yaxis
- set_y
- set_y_axis
- y_axis
In Matplotlib, the get_yaxis attribute represents the y-axis of an Axes object. This attribute allows you to access and modify properties of the y-axis, such as tick locations and labels.
The ____ decorator is used to convert a function into a static method.
- @classmethod
- @classmethod
- @staticmethod
- @staticmethod()
In Python, the @staticmethod decorator is used to define a static method within a class. Static methods are methods that belong to a class rather than an instance and can be called on the class itself. They don't have access to the instance's state.
The ____ function in Pandas is used to load a dataset from a CSV file into a DataFrame.
- import_data
- load_csv
- read_csv
- read_data
In Pandas, the read_csv function is used to read data from a CSV file and create a DataFrame, which is a fundamental operation for data manipulation and analysis in Python.
In Seaborn, the ____ function is used to plot univariate or bivariate distributions of observations.
- distplot
- plot_distribution
- scatterplot
- univariate
In Seaborn, you use the distplot function to plot univariate distributions of observations. It's a versatile function that can display histograms, kernel density estimates, and more.
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 the context of data visualization, ____ is a Python library that is based on Matplotlib and provides a high-level interface for drawing attractive and informative statistical graphics.
- NumPy
- Scikit-learn
- Seaborn
- TensorFlow
In the context of data visualization in Python, Seaborn is a library based on Matplotlib that simplifies the creation of statistical graphics, making them more attractive and informative.
In the pytest framework, how do you mark a test function so that it is not executed by the test runner?
- @pytest.disable()
- @pytest.exclude()
- @pytest.ignore()
- @pytest.skip("Test not ready yet")
In pytest, you can use the @pytest.skip("Reason") decorator to mark a test function so that it is not executed. You can provide a reason for skipping for documentation purposes.
In the unittest framework, what is the significance of the setUpClass method in a test case class?
- It is called after all test methods in the test case class have run.
- It is called after the tearDown method in the test case class.
- It is called before any test methods in the test case class are run.
- It is called before each test method in the test case class.
In the unittest framework, the setUpClass method is called once before any test methods in the test case class are run. It's typically used to set up resources or configurations that are shared by all test methods in the class.
In web development, ____ is a technique used to update a web page without reloading it, which can be implemented using JavaScript and integrated with Python back-end.
- AJAX
- CSS
- HTML5
- JSON
In web development, AJAX (Asynchronous JavaScript and XML) is a technique used to update web content without the need to reload the entire page. It enables seamless interaction between the client and server, often implemented using JavaScript and integrated with Python back-end using APIs.
