Why does this code gets no output?

Question

def f(H):
X=[2,3,5,7,11,13,17,19,23,29]
Y=float(H)
Z=float(X[0])
K=[]
while Z!=500:
if Y/Z !=1:
if Y%Z==0:
K.append(Z)
Y=Y/Z
else:
Z+=1
else:
K.append(1)
M=len(K)-1
N=K[0:M]
return (1)
else:
return ("number not valid")

f(input("n"))

Answer 1

Because there's no print statement anywhere.

Answer 2

You can also print the return value (if there is one) directly:

print(f(input("n")))

Answer 3

Then should I asign a variable with f(input("n")) and then print it
