The sample recursive Python Function is given below. See the definition of a Recursive Python Function.

What is a Recursive Python Function?

A recursive function is one that defines itself in terms of itself using self-referential phrases.

This signifies that the function will keep calling itself and repeating its action until some condition is fulfilled and a result is returned.

Sample Recursive Python Function is:

def remove_all0(x,s):

   while s!=[]:

       if x == s[0]:

           ss = [s[1]] + remove_all0(x,s[2:])

           return ss

       else:

           s1 = [s[0]] + remove_all0(x, s[1:])

           return s1

   if s==[]:

       return s

print(remove_all0(3,[4,3,5,6,3,2,1]))
