How to make the plot not disappear?

Question

Suppose you need to store the figure and subplot in variables (to later modify attributes). How can you make the whole figure to stay and not quickly disappear after some millisecs?

import matplotlib.pyplot as plt

fig = plt.figure() 

ax = fig.add_subplot(2,2,1)
ax.plot(1)

fig.show()

Answer 1

Change fig to plt:

plt.show()
