How to get unique values from Numpy array

import numpy as np
a = np.array([1,1,2,1,2])
uniq = np.unique(a)

import numpy as np - load lib:Numpy module for Python
np.array - declare Numpy array
[1,1,2,1,2] - sample array
.unique( - returns unique values only from specified array
uniq - will contain array with unique values only

group: uniq

Example:

import numpy as np
a = np.array([1,1,2,1,2])
uniq = np.unique(a)
print(uniq)
print(type(uniq))
