python - Close a figure - PyCharm

Question

I have spent over an hour searching, just to figure this simple thing. So, before considering this a duplicate question, please compare my question to any question out there.

This is my code:

import pandas
import matplotlib.pyplot as plt

dataset = pandas.read_csv('international-airline-passengers.csv', usecols=[1], engine='python', skipfooter=1)
print dataset, type(dataset)
plt.plot(dataset)
plt.show()
plt.close()

Firstly, plt.show() to my understanding is a blocking function. So what is the way to close the figure. There is no point in writing plt.close() after it. So where is the right way to put it.

Secondly, how can I make sure all the windows are closed when I execute a new process of the same python code. For example in MATLAB, one could easily say close all in the beginning of their file and it closes all the opened plots which were the result of previous MATLAB code execution. plt.close('all') is not working either.

I am using PyCharm. The results I found for the first situation, might work on IDLE but not in the PyCharm. How can I do it PyCharm.

Answer 1

plt.show(block=False) will do the trick- This is the way you can make this function non-blocking (both in run & debug mode). The main dis-advantage is that if the code ends, the figure is automatically closes...
