Python
Method 1
num = int(input("Enter a number: "))
if num ==0:
print('Neither positve nor negative')
elif num>0:
print('Positive number')
else:
print('Negative number')
Method 2
num=int(input("Enter a number:"))
print("Positive" if num>0 else ("Negative" if num<0 else "Neither positive nor negative"))
