Python | sympy from_rgs() method Last Updated : 13 Aug, 2019 Improve Improve Like Article Like Save Share Report With the help of sympy.combinatorics.Partition.from_rgs() method, we can get the array of subarrays by passing array of indexes and list of members by using sympy.combinatorics.Partition.from_rgs() method. Syntax : sympy.combinatorics.Partition.from_rgs() Return : Return the array of subarrays. Example #1 : In this example we can see that by using sympy.combinatorics.Partition.from_rgs() method, we are able to get the array of subarray by passing array of indexes and list of members as passed by parameters. # import sympy and Relational from sympy.combinatorics.partitions import Partition from sympy import * x, y = symbols('x y') # Using from sympy.combinatorics.Partition.from_rgs() method gfg = Partition.from_rgs([0, 1, 2, 0, 1, 2], list('abcdef')) print(gfg) Output : {{a, d}, {b, e}, {c, f}} Example #2 : # import sympy and Relational from sympy.combinatorics.partitions import Partition from sympy import * x, y = symbols('x y') # Using from sympy.combinatorics.Partition.from_rgs() method gfg = Partition.from_rgs([0, 1, 2, 0, 1, 2, 3, 4, 3, 4, 0, 1, 5], list('abcdefghijklm')) print(gfg) Output : {{m}, {c, f}, {g, i}, {h, j}, {a, d, k}, {b, e, l}} Like Article Suggest improvement Previous sympy.frac() method in Python Next Python | sympy Relational() method Share your thoughts in the comments Add Your Comment Please Login to comment...
