## Print factorial of a number in Python

Letâ€™s see** python program to print factorial of a number**.

- Firstly, the number whose
**factorial**is to be found is stored in**Num**. - Declare and initialize the factorial variable to 1.
- We will use an
**if-else**statement to check whether the number is**negative**,**zero**, or**positive**. - The
**for loop**and**range()**function is used if the number is positive to calculate the factorial of a number. - At last,
**print**is used to get the factorial of a number.

**Example:**

```
Num = 5
Factorial = 1
if Num < 0:
print("Factorial does not exist for negative numbers")
elif Num == 0:
print("The factorial of 0 is 1")
else:
for i in range(1, Num + 1):
Factorial = Factorial * i
print("The factorial of",Num,"is",Factorial)
```

We can see that the factorial of a number is **120 **in the output. You can refer to the below screenshot for the output.

The above code, we can use to **print factorial of a number in Python**.

## Python program to print factorial of a number using function

Now, we will see **python program to print factorial of a number using function**.

- In this example, we have defined the function as
**factorial(num)**. - To find the
**factorial**we have used a single line**if-else**statement and also we have assigned the**number as 6**for whose factorial is to be found. - At last,
**print**is used to get the factorial of a number.

**Example:**

```
def factorial(num):
return 1 if (num==1 or num==0) else num * factorial(num-1);
number = 6
print("The factorial of",number,"is",factorial(number))
```

We can see that the factorial of a number is **720 **in the output. You can refer to the below screenshot for the output.

This is how to **print factorial of a number using function in Python**.

## Python program to print factorial of a number using for loop

Here, we will see **python program to print factorial of a number using for loop**

- Firstly, we will take the
**input**from the user whose factorial is to be found. - Declare and initialize the Fact variable to 1.
- The
**for loop**and**range()**function is used to calculate the factorial of a number. - At last,
**print**is used to get the factorial of a number.

**Example:**

```
num = int(input("Enter a number:"))
Fact = 1
for i in range(1, num + 1):
Fact = Fact * i
print("The Factorial of",num,"is",Fact)
```

We can see that the factorial of a number is** 24 **in the output. You can refer to the below screenshot for the output.

The above code, we can use to **print factorial of a number using for loop in Python**.

## Python program to find factorial of a number using recursion

Now, we will see **python program to find factorial of a number using recursion**.

- Here, we will use recursion to find the factorial of a number.
- In this example, we have defined the function as
**recursion_factorial(n)** - We will store the value in
**number**. We will use an**if-else**statement to check whether the number is**negative**,**zero**, or**positive**. - The
**number**is passed to the**recursion_factorial()**function to compute the factorial of the number.

**Example:**

```
def recursion_factorial(n):
if n == 1:
return n
else:
return n*recursion_factorial(n-1)
number = 8
if number < 0:
print("Factorial does not exist for negative numbers")
elif number == 0:
print("The factorial of 0 is 1")
else:
print("The factorial of", number, "is", recursion_factorial(number))
```

We can see that the factorial of a number is** 40320 **in the output. You can refer to the below screenshot for the output.

The above code is to **find factorial of a number using recursion in Python**.

## Python program to print factorial of a number by getting input from a user

Let see **python program to print factorial of a number by getting input from a user**

- Firstly, we will take the
**input**from the user whose factorial is to be found. - Declare and initialize the
**fact**variable to**1**. - We will use an
**if-else**statement to check whether the number is**negative**,**zero**, or**positive**. - The
**for loop**and**range()**function is used if the number is positive to calculate the factorial of a number. - At last,
**print**is used to get the factorial of a number.

**Example:**

```
num = int(input("Enter a number:"))
fact = 1
if num < 0:
print("Factorial does not exist for negative numbers")
elif num == 0:
print("The factorial of 0 is 1")
else:
for i in range(1,num+1):
fact = fact * i
print("The Factorial of",num,"is",fact)

**if-else**statement to check whether the number is**negative**,**zero**, or**positive**. - A
**while loop**is used to multiply the number to find the factorial in a continuing process. - The process continues until the value of the number is greater than zero.
- At last,
**print**is used to get the factorial of a number.

**Example:**

```
num=int(input("Enter a number to find factorial: "))
fact=1;
if num<0:
print("Factorial does not defined for negative integer");
