Python| sympy.trailing() 方法

在sympy.trailing()方法的帮助下，我们可以计算给定数字的二进制表示中尾随零位的数量，即确定除以该数字的 2 的最大幂。

Syntax:
trailing(n)

Parameter:
n – It denotes the number for which the largest power of 2 that divides that number is determined.

Returns:
Returns the largest power of 2 that divides the given number.

示例 #1：

# import trailing() method from sympy
from sympy.ntheory.factor_ import trailing
   
n = 64
   
# Use trailing() method 
trailing_n = trailing(n) 
       
print("The largest power of 2 that divides {} is 2^{}.".
      format(n, trailing_n))

输出：

The largest power of 2 that divides 64 is 2^6.

示例 #2：

# import trailing() method from sympy
from sympy.ntheory.factor_ import trailing
  
n = 130
  
# Use trailing() method 
trailing_n = trailing(n) 
      
print("The largest power of 2 that divides {} is 2^{}.".
      format(n, trailing_n))

输出：

The largest power of 2 that divides 130 is 2^1.
