Using the sympy.combinatorics.Partition().rank method, we can get the rank of the array of subarrays, which is passed as parameters to sympy.combinatorics.Partition () .rank .

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

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

# import sympy and Partition

from sympy.combinatorics.partitions import Partition

from sympy import * x, y = symbols ( `xy` )

 
# Using sympy.combinatorics.partitions.Partition (). Rank method

gfg = Partition ([ 1 , 2 ], [ 4 , 5 , 6 ], [ - 12 , - 11 ])

 

print (gfg.rank)

Output:

119

Example # 2:

# impo rt sympy and Relational

from sympy.combinatorics.partitions import Partition

from sympy import * x, y = symbols ( ` xy` )

 
# Using sympy.combinatorics.partitions.Partition (). Rank method

gfg = Partition ([ 3 ], [ 1 , 91 ], [ 2 ], [ 6 ])

 

print (gfg.rank)

Output:

47
