x = -10 if x < 0: print("The negative number", x,"is not valid here.") else: if x > 0: print(x,"is a positive number") else: print(x,"is 0")

Understand the Problem

The question is presenting a piece of code that checks if a number is positive, negative or zero and prints corresponding messages. The code is using conditional statements to perform these checks.

More Information

The program checks if the value of 'x' is negative, positive, or zero. In this case, 'x' is -10, a negative number. The code then prints a message stating that the negative number is not valid.

Tips

A common mistake is using incorrect syntax or indentation that prevents the code from running correctly in Python.
