<bot>: Here is a Python code to binomial coefficients

import math

def binom(n, k):
  """
  Returns the binomial coefficient (n choose k).
  """
  if (k > n):
    return 0
  if (k == 0):
    return 1
  if (k == 1):
    return n
  return binom(n - 1, k - 1) + binom(n - 1, k)

# Enter the values
n = 5
k = 3

# Calling the function
print((binom(n, k)))

#Example Output
# 10
