Python| sympy.smoothness() 方法

借助sympy.smoothness()方法，我们可以找到给定数字的平滑度和幂平滑度。一个数的平滑度是它最大的素因数，幂平滑度是它的最大除数提升到它的多重性。

Syntax:
smoothness(n)

Parameter:
n – It denotes the number for which the smoothness and power-smoothness is calculated.

Returns:
Returns a tuple of smoothness and power-smoothness of the given number.

示例 #1：

# import smoothness() method from sympy
from sympy.ntheory.factor_ import smoothness
   
n = 64
   
# Use smoothness() method 
smoothness_n, power_smoothness_n = smoothness(n) 
       
print("The smoothness and power-smoothness of {} is {} and {} respectively".
      format(n, smoothness_n, power_smoothness_n))

输出：

The smoothness and power-smoothness of 64 is 2 and 64 respectively

示例 #2：

from sympy.ntheory.factor_ import smoothness
   
n = 2**4 * 13
   
# Use smoothness() method 
smoothness_n, power_smoothness_n = smoothness(n) 
       
print("The smoothness and power-smoothness of {} is {} and {} respectively".
      format(n, smoothness_n, power_smoothness_n))

输出：

The smoothness and power-smoothness of 208 is 13 and 16 respectively
