Python | sympy rank() method

With the help of sympy.combinatorics.Partition().rank method, we can get the rank of an array of subarrays that is passed as parameters in sympy.combinatorics.Partition().rank method.

Syntax : sympy.combinatorics.Partition().rank
Return : Return the rank of subarrays.

Example #1 :
In this example we can see that by using sympy.combinatorics.Partition().rank method, we are able to get the rank of array of subarrays.

# import sympy and Partition
from sympy.combinatorics.partitions import Partition
from sympy import * x, y = symbols('x y')

# Using sympy.combinatorics.partitions.Partition().rank method
gfg = Partition([1, 2], [4, 5, 6], [-12, -11])

print(gfg.rank)

Output :

119

Example #2 :

# import sympy and Relational
from sympy.combinatorics.partitions import Partition
from sympy import * x, y = symbols('x y')

# Using sympy.combinatorics.partitions.Partition().rank method
gfg = Partition([3], [1, 91], [2], [6])

print(gfg.rank)

Output :

47
