How Well Do You Know Python?

1. Which is a python package used for 2D graphics?

Matplotlib.pyplot

Matplotlib.pip

Matplotlib.numpy

Matplotlib.plt

matplotlib.pyplot is a python package used for 2D graphics. It is a sub-package of the matplotlib library and provides a convenient interface for creating various types of plots and visualizations. It is commonly used for creating line plots, scatter plots, bar plots, histograms, and many other types of plots. The pyplot module provides functions that allow users to easily create and customize plots, add labels and titles, adjust axes, and apply various formatting options to enhance the visual appearance of the plots.

2. Identify the package manager for Python packages, or modules.

Matplotlib

PIP

Plt.show()

Python package

PIP is the package manager for Python packages or modules. It is a command-line tool that allows users to easily install, upgrade, and manage Python libraries and dependencies. PIP simplifies the process of installing external packages and ensures that the required dependencies are also installed. It is widely used in the Python community and is the recommended package manager for Python.

3. Observe the output figure. Identify the coding for obtaining this output.

Import matplotlib.pyplot as pltplt.plot([1,2,3],[4,5,1])plt.show()

Import matplotlib.pyplot as pltplt.plot([1,2],[4,5])plt.show()

Import matplotlib.pyplot as pltplt.plot([2,3],[5,1])plt.show()

Import matplotlib.pyplot as pltplt.plot([1,3],[4,1])plt.show()

The correct answer is the first option, "import matplotlib.pyplot as plt\n\nplt.plot([1,2,3],[4,5,1])\nplt.show()". This is because this code imports the necessary library, creates a plot with the given x and y values, and displays the plot using the "show()" function. The resulting plot matches the output figure shown.

4. Identify the right type of chart using the following hints. Hint 1: This chart is often used to visualize a trend in data over intervals of time. Hint 2: The line in this type of chart is often drawn chronologically.

Line Chart

Bar Chart

Pie Chart

Scatter Plot

A line chart is the right type of chart based on the given hints. It is commonly used to visualize trends in data over time intervals and the line in this chart is typically drawn chronologically. This type of chart is effective in showing how data points change over time and is often used in analyzing and presenting time series data.

5. To install matplotlib, the following function will be typed in your command prompt. What does "-U"represents? Python –m pip install –U pip

Downloading pip to the latest version

Upgrading pip to the latest version

Removing pip

Upgrading matplotlib to the latest version

The "-U" in the given command represents upgrading pip to the latest version.

Explanation

The "-U" in the given command represents upgrading pip to the latest version.

6. Which key is used to run the module?

F6

F4

F3

F5

F5 is the correct answer because it is the key used to run the module. Pressing F5 will execute the code in the module and display the output or perform the desired action. The other options, F6, F4, and F3, are not typically used for running modules in most programming environments.

7. The plot method on Series and DataFrame is just a simple wrapper around ____________

Gplt.plot()

Plt.plot()

Plt.plotgraph()

None of these

The correct answer is plt.plot(). The plot method on Series and DataFrame is a simple wrapper around the plt.plot() function. This function is part of the matplotlib library, which is a widely used plotting library in Python. By using plt.plot(), we can easily create various types of plots such as line plots, scatter plots, and bar plots. Therefore, plt.plot() is the correct choice for the plot method on Series and DataFrame.

8. Read the statements given below. Identify the right option from the following for pie chart. Statement A: To make a pie chart with Matplotlib, we can use the plt.pie() function. Statement B: The autopct parameter allows us to display the percentage value using the Python string formatting.

Statement A is correct

Statement B is correct

Both the statements are correct

Both the statements are wrong

Both statements A and B are correct. Statement A states that to make a pie chart with Matplotlib, we can use the plt.pie() function, which is true. Matplotlib is a popular data visualization library in Python, and plt.pie() is one of its functions specifically designed for creating pie charts. Statement B mentions the autopct parameter, which is used to display the percentage value in the pie chart using Python string formatting. This is also true as autopct allows us to customize the format of the percentage value displayed in the chart.

9. Read the code: a. import matplotlib.pyplot as plt b. plt.plot(3,2) c. plt.show()

Identify the output for the above coding.

Option 1

Option 2

Option 3

Option 4

The code is using the matplotlib library to plot a point at coordinates (3,2) on a graph. The plt.show() function is then used to display the graph. Therefore, the output of the code would be a graph with a single point at the coordinates (3,2).
