To find the factorial of a number in Python, you can use a for loop to iterate over a range of numbers and compute the factorial of the given number. Here’s an example:

```				```
# define a function to compute the factorial of a number
def factorial(n):
# initialize the factorial to 1
fact = 1

# iterate over a range of numbers from 1 to the given number
for i in range(1, n+1):
# multiply the factorial by the current number
fact = fact * i

# return the factorial
return fact

# get the number from the user
num = int(input("Enter a number: "))

# compute and print the factorial of the given number
print(f"The factorial of {num} is {factorial(num)}")

```
```

This code defines a function called `factorial()` that takes a single argument `n`, which is the number for which we want to compute the factorial. Inside the function, we initialize a variable called `fact` to 1, which will hold the result of the factorial. Then, we use a for loop to iterate over the range of numbers from 1 to the given number `n`, and multiply the factorial by each number in the range. Finally, we return the factorial.

To use the `factorial()` function, we get the number from the user using the `input()` function, and then pass it to the `factorial()` function as an argument. The `factorial()` function returns the factorial of the given number, which we then print using the `print()` function.

Here’s an example of how this code would work:

```				```
Enter a number: 5
The factorial of 5 is 120

```
```

In this example, the user entered the number 5, so the `factorial()` function computed the factorial of 5, which is 120.
