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的行的二项式系数。
语法: binomial_coefficients_list(n)
参数 :
n –它表示一个整数。
返回:返回一个二项式系数的列表,作为帕斯卡三角形的行数。
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]
