To enable a specific and accurate analysis, always show your code (properly formatted, of course)! Even better, make a snapshot of your workspace and post the link to it here.

Formatting instructions can be found in the Markdown Cheatsheet pop-up below "Add an Answer" :arrow_heading_down:

try: count - int(input("Give me a number: ")) except ValueError: print("That's not a number!") else: print("Hi " * count)

As I said in your other question, I suspect you meant to assign the variable count (with "='), not subtract from it (with "-").

Hi there! I took the liberty of forking your workspace and taking a look When I do this command python Exceptions.py I get an error saying that count is not defined. . And the reason it's saying that is because you have a typo.

You have typed:

count - int(input("Give me a number: "))

But you meant to type:

count = int(input("Give me a number: "))

Note the equals instead of the minus sign. The minus sign indicates that you are trying to deduct the number input by the user from the current value stored in count. But as this is the first appearance of the count variable, it is currently undefined and has no value. The equals sign, on the other hand, will take the input from the user and try to turn it into an integer. If it succeeds, it will assign the value to count, at which point the count variable will be defined.

Make this tiny change, and your program should run! :sparkles:

Perhaps you're giving the wrong command to start it.

I used:
