Python| sympy.binomial_coefficients_list() 方法

在sympy.binomial_coefficients_list()方法的帮助下，我们可以找到作为帕斯卡三角形行的二项式系数。

Syntax: binomial_coefficients_list(n)

Parameter:
n – It denotes an integers.

Returns: Returns a list of binomial coefficients as rows of the Pascal’s Triangle.

示例 #1：

# import binomial_coefficients_list() method from sympy
from sympy.ntheory import binomial_coefficients_list
  
n = 6
  
# Use binomial_coefficients_list() method 
binomial_coefficients_list_n = binomial_coefficients_list(n) 
      
print("{}th row of Pascal's Triangle = {} ".format(n, binomial_coefficients_list_n))

输出：

6th row of Pascal's Triangle = [1, 6, 15, 20, 15, 6, 1] 

示例 #2：

# import binomial_coefficients_list() method from sympy
from sympy.ntheory import binomial_coefficients_list
  
n = 9
  
# Use binomial_coefficients_list() method 
binomial_coefficients_list_n = binomial_coefficients_list(n) 
      
print("{}th row of Pascal's Triangle = {} ".format(n, binomial_coefficients_list_n))

输出：

9th row of Pascal's Triangle = [1, 9, 36, 84, 126, 126, 84, 36, 9, 1]
