Python | sympy.genocchi() method

The genocchi() function in SymPy is used to compute the Genocchi numbers. Genocchi numbers are a sequence of integers that arise in the area of number theory.

The Genocchi number of the nth order is given by:

G(n)=(2−2n)B(n)

Where B(n) is the nth Bernoulli number.

Here's how you can use the genocchi() function in SymPy:

from sympy import genocchi

# Compute the first few Genocchi numbers
for n in range(10):
    print(f"G({n}) = {genocchi(n)}")

Please note that Genocchi numbers are often defined only for positive even integers, and the Genocchi function may return 0 for odd integers (except for 1).
