Python sympy | sieve.primerange() method

With the help of sympy.sieve.primerange() method, we can generate all prime numbers for a given range [a, b). It returns a type generator object which can be converted to a list for further operations.

Syntax: sieve.primerange(a, b)
Parameters:
a – It denotes the start of the range. It is inclusive.
b – It denotes the end of the range. It is not inclusive.
Returns: The method returns a type generator object.

Example #1:

# import sympy
from sympy import sieve

# Use sieve.primerange() method
prime_gen = sieve.primerange(1, 10)
prime_list = list(prime_gen)

print("Prime numbers for the range of numbers [1, 10) : {}".format(prime_list))

Output:

Prime numbers for the range of numbers [1, 10) : [2, 3, 5, 7]

Example #2:

# import sympy
from sympy import sieve

# Use sieve.primerange() method
prime_gen = sieve.primerange(8, 50)
prime_list = list(prime_gen)

print("Prime numbers for the range of numbers [8, 50) : {}".format(prime_list))

Output:

Prime numbers for the range of numbers [8, 50) : [11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47]
