How to prevent jupyter notebook from plotting figure returned by a function
问题
我有一个简单的函数：
def return_fig():
fig = plt.figure()
plt.plot([1,2,3,4,5],[1,2,3,4,5])
return fig
在Jupyter笔记本中，我定义了这个函数并导入了matplotlib.pyplot：
import matplotlib.pyplot as plt
在一个新的单元格中，我有：
figure = return_fig()
当我执行该单元格时，图形会立即显示。然而，我只想要图形对象存在，并且稍后可以使用 plt.show() 来显示它。这是在常规Python脚本中发生的情况，但不适用于Jupyter笔记本。我漏掉了什么？

I have a simple function:
def return_fig():
fig = plt.figure()
plt.plot([1,2,3,4,5],[1,2,3,4,5])
return fig
In a jupyter notebook, I define this function and
import matplotlib.pyplot as plt
In a new cell, I have
figure = return_fig()
When I execute the cell, the figure gets shown immediately. However, I just want the figure object to exist, and to be able to show it with plt.show() later on. This is what happens within a regular python script, but not within a jupyter notebook. What am I missing?

Maybe plt.close() helps.
def return_fig():
fig = plt.figure()
plt.plot([1,2,3,4,5],[1,2,3,4,5])
plt.close(fig)
return fig
Run:
>>> figure = return_fig()
>>> figure
Output:
