Python sympy.binomial_coefficients_list()用法及代碼示例

借助sympy.binomial_coefficients_list()方法，我們可以找到二項式係數作為Pascal三角形的行。

用法： binomial_coefficients_list(n)

參數：
n – 它表示一個整數。

返回值：返回二項式係數列表，作為Pascal三角形的行。

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))

輸出：

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))

輸出：

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