Python language allows various mathematical operations, that has applications in scientific domain and in data science. Python has an in-built function which computes the gamma value numerically of the value of number pass into the function.
Code 1: Demonstration of working of gamma()
Comparing factorial() and gamma():
We can find the value of gamma using factorial (x-1), but we use gamma() because when a similar task is there for both functions, gamma() offers better performance.
