With the help of sympy.catalan() method, we can find the Catalan number in SymPy. It is denoted as –
Syntax: catalan(n)
Parameter:
n – It denotes the nth Catalan number.Returns: Returns the nth Catalan number.
Example #1:
# import sympy from sympy import * n = 4print("Value of n = {}".format(n)) # Use sympy.catalan() method nth_catalan = catalan(n) print("Value of nth catalan number : {}".format(nth_catalan)) |
Output:
Value of n = 4 Value of nth catalan number : 14
Example #2:
# import sympy from sympy import * n = 15print("Value of n = {}".format(n)) # Use sympy.catalan() method nth_catalan = catalan(n) print("Value of nth catalan number : {}".format(nth_catalan)) |
Output:
Value of n = 15 Value of nth catalan number : 9694845
