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.

**Code 2: **Comparison of factorial() and gamma()

So, to learn more about functions in python for data science, you can check this and this as well. These blogs will help you in understanding the field of data science better.
