Write a program that repeatedly prompts a user for integer numbers until the user enters 'done'. Once 'done' is entered, print out the largest and smallest of the numbers. If the user enters anything other than a valid number catch it with a try/except and put out an appropriate message and ignore the number.

Hi man, try this code

You can try this:

num_set = []

def check_num():
    while True:
        try:
            num = input("Enter a number or type 'done': ")
            lower_num = num.lower()
            if lower_num == "done":
                return
            isinstance(num, int)
            num = int(num)
            num_set.append(num)
        except:
            print("Invalid input")
       
def check_size():
    if not num_set:
        return  
    else:
        print("Maximum is", max(num_set))
        print("Minimum is", min(num_set))
                               
check_num()
check_size()

added an if statement to check if the list is empty.

if bool(num_list):
# If the list is not empty, it will print the max and min numbers.
print(f"Maximum is {max(num_list)}")
print(f"Minimum is {min(num_list)}")

If the list is empty, it will print the below statement.

#My solution: Indentation is important and remembering when inputting the numbers don't space by accident.
No need to add space after is in the print Function because the input function would add the space before.

What is the role of 'continue' statement in the 'except:' part of the code after the print statement?
