# Python | sympy.primorial() method

• Last Updated : 27 Aug, 2019

With the help of sympy.primorial() method, we can find the product of the first n primes (default) or the primes less than or equal to n (when nth=False), where n and nth are parameters to the method.

Syntax: primorial(n, nth)

Parameter:
n – It denotes the number for which the product of first n primes or prime less than or equal to n is calculated.
nth – It denotes a boolean value. When True, it returns the product of first n primes whereas when False returns the product of primes less than or equal to n.

Returns: Returns the product of the first n primes or the primes less than or equal to n .

Example #1:

 `# import primorial() method from sympy``from` `sympy ``import` `primorial`` ` `n ``=` `3`` ` `# Use primorial() method ``primorial_n ``=` `primorial(n) ``# 2 * 3 * 5``     ` `print``(``"The product of first {} primes is {}"``.``format``(n, primorial_n))`

Output:

```The product of first 3 primes is 30
```

Example #2:

 `# import primorial() method from sympy``from` `sympy ``import` `primorial`` ` `n ``=` `10`` ` `# Use primorial() method ``primorial_n ``=` `primorial(n, nth ``=` `False``) ``# 2 * 3 * 5 * 7``     ` `print``(``"The product of primes less than or equal to {} is {}"``.``format``(n, primorial_n))          `

Output:

```The product of primes less than or equal to 10 is 210
```
