How could I mess up here?

Question

Python

I just don't see where I could have gone wrong...
print(z:=int(input("How much does a watermelon weigh?"))));
If ((z//2)==0 and z!=2):
print('Yes')
else:
print("No")

Answer 1

1. if with a small one.
2. not ":=" but "="

z = int(input("Сколько весит арбуз?"))

if ((z//2)==0 and z!=2):
    print('Yes')
else:
    print("No")
