Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. The Axes Class contains most of the figure elements: Axis, Tick, Line2D, Text, Polygon, etc., and sets the coordinate system. And the instances of Axes supports callbacks through a callbacks attribute.

matplotlib.axes.Axes.get_path_effects() Function

The Axes.get_path_effects() function in axes module of matplotlib library is used to get the property of set_path_effects.
Syntax: Axes.get_path_effects(self) Parameters: This method does not accepts any parameter. Returns: This method return the property of set_path_effects.
Below examples illustrate the matplotlib.axes.Axes.get_path_effects() function in matplotlib.axes: Example 1: Python3
# Implementation of matplotlib function
import matplotlib.pyplot as plt
import numpy as np
import matplotlib.patheffects as path_effects
 
    
fig, ax = plt.subplots()
t = ax.text(0.02, 0.5,
            'GeeksForGeeks', 
            fontsize = 40,
            weight = 1000, 
            va ='center')

t.set_path_effects([path_effects.PathPatchEffect(offset =(4, -4), 
                                                 hatch ='xxxx',
                                                 facecolor ='gray'),
                    path_effects.PathPatchEffect(edgecolor ='white',
                                                 linewidth = 1.1,
                                                 facecolor ='black')])
  
print("Value Return by get_path_effects() : \n")
for i in t.get_path_effects():
    print(i)
 
 
fig.suptitle('matplotlib.axes.Axes.get_path_effects() \
function Example\n\n', fontweight ="bold")

plt.show()
Output:
Value Return by get_path_effects() :

Example 2: Python3
# Implementation of matplotlib function
import matplotlib.pyplot as plt
import matplotlib.patheffects as PathEffects
import numpy as np

 
fig, ax1 = plt.subplots()
ax1.imshow([[1, 2], [2, 3]])
txt = ax1.annotate("Fourth",
                   (1., 1.), 
                   (0., 0),
                   arrowprops = dict(arrowstyle ="->",
                                     
                                     connectionstyle ="angle3", lw = 2),
                   size = 20, 
                   ha ="center", 
                   path_effects =[PathEffects.withStroke(linewidth = 3,
                                                         foreground ="w")])

txt.arrow_patch.set_path_effects([
    PathEffects.Stroke(linewidth = 5, foreground ="w"),
    PathEffects.Normal()])
 
ax1.grid(True, linestyle ="-")
 
pe = [PathEffects.withStroke(linewidth = 3,
                             foreground ="w")]

for l in ax1.get_xgridlines() + ax1.get_ygridlines():
    l.set_path_effects(pe)

print("Value Return by get_path_effects() : \n")

for l in ax1.get_xgridlines() + ax1.get_ygridlines():
    for i in l.get_path_effects():
        print(i)
 
fig.suptitle('matplotlib.axes.Axes.get_path_effects()\
function Example\n\n', fontweight ="bold")

plt.show()
Output:
Value Return by get_path_effects() :
