Factorial algorithm code written by various programmers

# New Programmer (recursion)

Def factorial (x ):

If x = 0:

Return 1

Else:

Return x * factorial (x-1)

Print factorial (6)

I am a beginner in Python. I found this article interesting on the Internet, so I want to rewrite it in my blog.

On the one hand, you can improve your Python level, and you can also learn and share with more Python enthusiasts.
