• Last Updated : 28 Aug, 2019

With the help of sympy.udivisor_count() method, we can count the number of unitary divisors of the given integer.

Syntax: udivisor_count(n, modulus=1)

Parameter:
n – It denotes an integer.

Returns: Returns the count of unitary divisors of the given integer.

Example #1:

 `# import divisor_count() method from sympy``from` `sympy.ntheory.factor_ ``import` `udivisor_count`` ` `n ``=` `84`` ` `# Use udivisor_count() method ``udivisor_count_n ``=` `udivisor_count(n) ``     ` `print``(``"The unitary number of divisors of {} : {}"``.``format``(n, udivisor_count_n))`

Output:

```The unitary number of divisors of 84 : 8
```

Example #2:

 `# import divisor_count() method from sympy``from` `sympy.ntheory.factor_ ``import` `udivisor_count`` ` `n ``=` `210`` ` `# Use udivisor_count() method ``udivisor_count_n ``=` `udivisor_count(n) ``     ` `print``(``"The unitary number of divisors of {} : {}"``.``format``(n, udivisor_count_n))`

Output:

```The unitary number of divisors of 210 : 16
```
