numpy.random.permutation() in Python

  • Last Updated : 15 Jul, 2020

With the help of numpy.random.permutation() method, we can get the random samples of sequence of permutation and return sequence by using this method.

Syntax : numpy.random.permutation(x)

Return : Return the random sequence of permuted values.

Example #1 :

In this example we can see that by using numpy.random.permutation() method, we are able to get the sequence of permutation and it will return the sequence by using this method.



Python3




# import numpy
import numpy as np
import matplotlib.pyplot as plt
  
# Using permutation() method
gfg = np.random.permutation(200)
  
count, bins, ignored = plt.hist(gfg, 14, density = True)
plt.show()

Output :

Example #2 :

Python3




# import numpy
import numpy as np
import matplotlib.pyplot as plt
  
arr = np.arange(12).reshape((4, 3))
# Using permutation() method
gfg = np.random.permutation(arr)
  
count, bins, ignored = plt.hist(gfg, 14, density = True)
plt.show()

Output :
