The binomial coefficient is the number of ways to choose `k` items from `n` items without repetition and without order. In Python, you can calculate the binomial coefficient using the `math.comb()` function.s
```py
from math import comb
def binomial_coefficient(n, k):
return comb(n, k)
binomial_coefficient(8, 2) # 28
```
