How do I close all the open pyplot windows (Matplotlib)?

plt.figure().close(): Close a figure window.

close() by itself closes the current figure

close(h), where h is a Figure instance, closes that figure

close(num) closes the figure with number=num

close(name), where name is a string, closes the figure with that label

close('all') closes all the figure windows

Example

from matplotlib import pyplot as plt fig = plt.figure() ax = fig.add_subplot() plt.show() plt.close()

Output

Now, swap the statements "plt.show()" and "plt.close()" in the code. You wouldn't get to see any plot as the output because the plot would already have been closed.
