I tried writing a code for the collatz func .But somehow i failed in it.i am just sharing the code which i tried.can you figure out the mistake
def my_input():
    a=input("enter:")
    collatz(a)
def myprint(y):
    print(y)
    if (y!=1):
        my_input()
def collatz(number):
    if (number%2)==0:
        return myprint(number/2)
    else:
        return myprint(3*number+1)
my_input()
