Factorial number in python with algorithm

## Q) : **Implement python script to print factorial of number .**

**Aim:**To print factorial number

**Algorithm:**

step 1; Start

step 2; Declare the variable n and read n value

step 3: Initialise fact = 1 and i = 1

step 4: In while loop perform

fact = fact * i

i = i + 1

step 5: print factorial of n

step 6: end

**Source Code:**

```
n = int(input('enter the number :'))
fact1 = 1
```

` `

`i = 1`

```
while n >= i:
fact2 = fact1 * i
i = i + 1
```

` print(f"factorial number of n is {fact2}")`

` `

Input:

`enter the number: 50`

` `

Outout:

```
enter the number :50
