# Python | sympy.compositepi() method

• Last Updated : 27 Aug, 2019

With the help of sympy.compositepi() method, we can find the number of composite numbers less than or equal to a given number.

Syntax: compositepi(n)

Parameter:
n – It denotes the number up to which the count of composite number is calculated.

Returns: Returns the number of composite numbers less than or equal to n.

Example #1:

 `# import compositepi() method from sympy``from` `sympy ``import` `compositepi`` ` `n ``=` `10`` ` `# Use compositepi() method ``count_composites ``=` `compositepi(n) ``     ` `print``(``"The number of composites numbers less than or equal to {} is {}"``.``format``(n, count_composites))`

Output:

```The number of composites numbers less than or equal to 10 is 5
```

Example #2:

 `# import compositepi() method from sympy``from` `sympy ``import` `compositepi`` ` `n ``=` `100`` ` `# Use compositepi() method ``count_composites ``=` `compositepi(n) ``     ` `print``(``"The number of composites numbers less than or equal to {} is {}"``.``format``(n, count_composites))          `

Output:

```The number of composites numbers less than or equal to 100 is 74
```
