Python sympy | sieve.search () method

Using the sympy.sieve.search () method, we can find the indices i, j of prime numbers that limit the given number. If the given number is prime, then i == j .

Syntax: sieve.search (n)
Parameter:
n - It denotes the number whose bounding prime indices is found.

Returns: Returns a tuple containing the bounding prime indices of n.

Example # 1:

# import sympy

from sympy import sieve

  
# Use the sieve.search () method

i, j = sieve.search ( 23

  

print ( " The bounding prime indices of the number 23: {}, {} " . format (i, j)) 

Exit :

 The bounding prime indices of the number 23: 9, 9 

Example # 2:

# import sympy

from sympy import sieve

 
# Use the sieve.search () method

i, j = sieve.search ( 25

 

print ( "The bounding prime indices of the number 23: {}, {}" . format (i, j)) 

Exit :

 The bounding prime indices of the number 23: 9, 10
