plt.show()

                                    from matplotlib import pyplot as plt

import matplotlib.pyplot as plt1

True

                                    import matplotlib.pyplot as plt # Import the matplotlib module
from matplotlib import style # Optionally you dont need to use style
style.use('ggplot') # Just for style

x = [10, 20, 30, 40, 50] # Get points to plot on graph

plt.plot(x) # We want to plot x on our graph
plt.show()

                                    # importing matplotlib module  
from matplotlib import pyplot as plt 
  
# x-axis values 
x = [5, 2, 9, 4, 7] 
  
# Y-axis values 
y = [10, 5, 8, 4, 2] 
  
# Function to plot scatter 
plt.scatter(x, y) 
  
# function to show the plot 
plt.show()
