Example 1: count values in array python

a = numpy.array([0, 3, 0, 1, 0, 1, 2, 1, 0, 0, 0, 0, 1, 3, 4])
unique, counts = numpy.unique(a, return_counts=True)
dict(zip(unique, counts))

# {0: 7, 1: 4, 2: 1, 3: 2, 4: 1}

a = arr.array(‘d’, [1.1, 2.1, 3.1])
len(a) # Output: 3

Example 4: find array length in python

a=arr.array('d', [1.1 , 2.1 ,3.1] )
len(a)
