Where do "none"s come from ?

Question

def max(x, y):
if x >=y:
### return x
print (x)
else:
### return y
print (y)

print(max(4, 7))
z = max(8, 5)
print(z)

Answer 1

look in above code u will get output as
7
None
8
None
because the function max() is not getting any value in return.. i know it's printing the right answer.. but the second and fourth line of the Output says that... it doesn't get any value from the function {when it reaches outside the function i.e. at line "print (max(4,7))"} 👈this line waits for a value but it gets nothing back from the function..

and the print statement just prints the values.. it doesn't transfers values.. return does that..

now if u just change the code.. as this https://code.sololearn.com/c1QC59f0LlmV/?ref=app
then u will find that the if the condition of "if statement" is true then it will "return x" to the function.. and if the condition is false it will "return y"

Answer 2
