With the help of sympy.sieve.totientrange() method, we can generate all totient 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.totientrange(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.totientrange() method totient_gen = sieve.totientrange( 1 , 10 ) totient_list = list (totient_gen) print ( "Totient numbers for the range of numbers [1, 10) : {}" . format (totient_list)) |
Output:
Totient numbers for the range of numbers [1, 10) : [1, 1, 2, 2, 4, 2, 6, 4, 6]
Example #2:
# import sympy from sympy import sieve # Use sieve.totientrange() method totient_gen = sieve.totientrange( 8 , 20 ) totient_list = list (totient_gen) print ( "Totient numbers for the range of numbers [8, 20) : {}" . format (totient_list)) |
Output:
Totient numbers for the range of numbers [8, 20) : [4, 6, 4, 10, 4, 12, 6, 8, 8, 16, 6, 18]
