Python| sympy.udivisors() 方法

借助sympy.udivisors()方法，我们可以默认按排序顺序找到给定数字的所有酉除数。

Syntax: udivisors(n, generator=False)

Parameter:
n – It denotes an integer.
generator – If generator is True an unordered generator object is returned, otherwise it returns a sorted list of unitary divisors. It is False by default.

Returns: Returns a list of all the unitary divisors of the given integer.

示例 #1：

# import udivisors() method from sympy
from sympy.ntheory.factor_ import udivisors
  
n = 84
  
# Use udivisors() method 
udivisors_n = udivisors(n) 
      
print("The unitary divisors of {} : {}".format(n, udivisors_n))

输出：

The unitary divisors of 84 : [1, 3, 4, 7, 12, 21, 28, 84]

示例 #2：

# import udivisors() method from sympy
from sympy.ntheory.factor_ import udivisors
  
n = -210
  
# Use udivisors() method 
udivisors_n = list(udivisors(n, generator = True)) 
      
print("The unitary divisors of {} : {}".format(n, udivisors_n))

输出：

The unitary divisors of -210 : [1, 2, 3, 6, 5, 10, 15, 30, 7, 14, 21, 42, 35, 70, 105, 210]
