💡 Hint

Common Mistakes

Importing 'plot' instead of 'FuncAnimation'.

Trying to import 'show' which is not for animation.

The FuncAnimation function from matplotlib.animation is used to create dynamic plots that update over time.

Complete the code to create a figure and axis for plotting.

Matplotlib

fig, ax = plt.[1]()

💡 Hint

Common Mistakes

Using 'plot' which only creates a plot, not figure and axes.

Using 'figure' which creates only the figure, not axes.

The subplots() function creates a figure and axes objects, which are needed for plotting and animation.

Fix the error in the update function to correctly update the line data.

Matplotlib

def update(frame):
    y = [i**2 for i in range(frame)]
    line.set_data(range(frame), [1])
    return line,

💡 Hint

Common Mistakes

Passing 'x' instead of 'y' to set_data.

Passing 'frame' which is just an integer, not data.

Passing 'line' which is the plot object, not data.

The set_data method needs both x and y data. Here, x is range(frame) and y is the list y calculated in the function.

Fill both blanks to create the animation object with the correct figure and update function.

Matplotlib

ani = FuncAnimation([1], [2], frames=10, interval=200)

💡 Hint

Common Mistakes

Using axis instead of figure as first argument.

Passing the line object instead of the update function.

The FuncAnimation needs the figure object and the update function to animate the plot.

hard

Fill all three blanks to set the x and y limits and start the animation.

Matplotlib

ax.set_xlim(0, [1])
ax.set_ylim(0, [2])
plt.[3]()

💡 Hint

Common Mistakes

Setting limits too small or too large causing plot to look empty.

Forgetting to call plt.show() to display the plot.

Set the x-axis limit to 10, y-axis limit to 100, and call plt.show() to display the animation.
