In this program, You will learn how to find factorial of a number using function in Python.

```
3! = 1 * 2 * 3 => 6
4! = 1 * 2 * 3 * 4 => 24
```

## Example: How to find factorial of a number using function in Python.

```
def find_factorial(n):
f = 1
for i in range(1, n + 1):
f = f * i
return f
x = int(input("Enter a number:"))
result = find_factorial(x)
print("Factorial is:", result)
```

#### Output:

```
Enter a number:4
Factorial is: 24
```
