# NumPy: Count number of occurrences of each value in a given array of non-negative integers

## NumPy Statistics: Exercise-13 with Solution

Write a Python program to count number of occurrences of each value in a given array of non-negative integers.

Note: bincount() function count number of occurrences of each value in an array of non-negative integers in the range of the array between the minimum and maximum values including the values that did not occur.

Sample Solution:-

Python Code:

``````import numpy as np
array1 = [0, 1, 6, 1, 4, 1, 2, 2, 7]
print("Original array:")
print(array1)
print("Number of occurrences of each value in array: ")
print(np.bincount(array1))
```
```

Sample Output:

```Original array:
[0, 1, 6, 1, 4, 1, 2, 2, 7]
Number of occurrences of each value in array:
[1 3 2 0 1 0 1 1]
```

Chain Operators

You can chain comparison operators in Python as following: n = 10 result = 1 < n < 20

```distance = 200
checker = 100 < distance < 350

print(checker)
```

Output:

`True`
